## Full text

Your clients probably don't care which feedback tool you use, as long as they can click something and leave a comment. That's the real question behind the Superflow vs Pastel debate. Your team cares a lot, though, especially once a project grows past a handful of pages or starts involving compliance-heavy clients. Both tools are built around that client-facing simplicity, but they handle everything behind it very differently.

**TLDR:**

- Pastel works for freelancers running simple feedback cycles, but has no AI, no PM sync, and no compliance docs
- Superflow's AI agents run QA checks automatically on every site change, covering accessibility, broken links, and spell check
- Pastel's PM integration exports comments as a static snapshot; Superflow syncs two-way with Asana, ClickUp, Jira, and more
- Pastel covers websites, images, and PDFs only; Superflow adds video and Lottie file review with the same approval flow
- Superflow holds SOC 2 Type II and HIPAA with BAA; Pastel has no equivalent compliance documentation available

## What Is Pastel?

Pastel is a link-based website feedback tool built around one idea: zero friction. You paste a URL, Pastel wraps it in a proxy canvas, and anyone with the link can click directly on the page to leave a comment. No install, no browser extension, no account required on the reviewer's end. It is [reviewed positively on Capterra](https://www.capterra.com/p/176456/Pastel/) for its ease of setup, and for a freelancer or small agency running straightforward review cycles, that reputation is earned.

### Features

- **Link-based review:** Share a URL and anyone can click to leave a comment. No account, no install, no browser extension required on the reviewer's end.
- **Multi-format support:** Covers websites, images, and PDFs. Every comment auto-captures a screenshot with browser and screen size metadata for easier bug reproduction.
- **Finish Review gate:** A built-in approval gate is available on every plan, including the free tier, giving clients a clear way to signal sign-off.
- **Responsiveness testing:** View and comment on sites at different viewport sizes to catch layout issues across screen sizes.
- **Tags and feedback deadlines:** Organize comments with labels and set due dates to keep review cycles on schedule.

### Limitations

- **No AI or automated checks:** Every issue found is one a person noticed and typed out. Nothing gets caught unless a human sees it first.
- **No per-client memory:** Every review starts from scratch. Pastel has no way to store brand guides, checklists, or past decisions, so recurring clients get no benefit from prior rounds.
- **One-way PM export only:** Comments can be pushed to PM tools, but there is no live two-way sync. Once comments leave Pastel they are static.
- **No video or motion asset support:** Pastel covers websites, images, and PDFs. There is no support for video, Lottie files, or other motion assets.
- **No compliance certifications:** No SOC 2, HIPAA with BAA, or audit trail appear in Pastel's public documentation, which rules it out for compliance-bound clients.

### Bottom Line

Pastel delivers exactly what it promises for freelancers and small agencies running simple feedback cycles on websites, images, or PDFs. The ceiling shows up fast once projects grow, clients multiply, or motion assets enter the mix. No AI, no per-client memory, no live PM sync, and no compliance documentation mean the tool fits a narrow slice of the agency market well and falls short outside it.

## What Is Superflow?

Superflow is an AI-powered QA and review tool built for web and marketing agencies. AI agents run your [QA checklist automatically](https://usesuperflow.ai/use-case/uat-qa-testing) on every site change, post findings as pinned comments, and hand off to a structured approval flow that ends with client sign-off. Clients approve from a shared link with no login required. The agency gets a full audit trail, two-way PM sync, and per-client Memory that gets sharper with every project.

### Features

- **AI QA agents:** Built-in agents cover accessibility, broken links, spell check, and OG image validation on every site change. You can build custom agents from any checklist or uploaded brand guide with no engineer required.
- **Per-client Memory:** Upload brand guides and checklists once per client. Memory learns from every review round, so agents get more accurate over time and rules never bleed between accounts.
- **Multi-asset workspace:** The same pinned-comment and approval flow covers websites, images, PDFs, video, and Lottie files. No separate tools for different asset types.
- **Two-way PM sync:** Connects to Asana, Monday.com, ClickUp, Trello, and Jira with live two-way sync. Comments create tasks, sign-offs close them, and status stays accurate in both places.
- **Compliance and audit trail:** SOC 2 Type II, HIPAA with BAA, SAML/SSO, SCIM, and data residency options. Every comment, AI finding, and approval is logged in a full audit trail for clients whose procurement teams ask for that paperwork.

### Limitations

- **AI credits are consumption-based:** Each agent review costs credits, so high-volume agencies should budget credit usage alongside seat costs.
- **Snippet install required for websites:** Reviewing a live site requires adding a snippet or using a one-click CMS install. It is a quick step, but it is a step. Pure proxy review with no install is not an option.
- **PM integrations start at Scale:** ClickUp, Asana, Monday.com, and webhooks are available from the Scale plan up, so teams on Growth will not get two-way task sync.

### Bottom Line

Superflow is built for agencies that run recurring QA cycles, deliver motion assets alongside web builds, or work with clients in regulated industries where compliance documentation is part of closing a contract. If your workflow has outgrown a shared Google Doc and a handful of emailed screenshots, this is where the upgrade pays off.

## Comparing Superflow and Pastel

We compared both of these tools on seven key criteria for teams or agencies looking at a feedback tool.

### Who Checks the Site

In Pastel, the answer is always a human. Every issue found is one a person noticed, clicked on, and typed out. Nothing gets checked unless someone sees it first. That works on a five-page site with a forgiving deadline. It breaks down fast on a 40-page build under pressure. Across [website annotation tools for teams](https://usesuperflow.ai/blog/website-annotation-tools-comparison), manual-only review is the most common point of failure.

In Superflow, AI agents do the first pass on every site change without waiting for anyone to open the page. Built-in agents cover accessibility, broken links, spell check, and OG image validation. Each one posts findings as pinned comments directly on the affected element, so your team sees exactly where the problem lives.

You can build custom agents from any checklist or uploaded brand guide. For [marketing agencies](https://usesuperflow.ai/user-persona/marketing-agencies) checking button copy consistency or verifying a client's color rules, those checks run on every deploy without anyone on your team running them manually.

Human review still happens. The agents run the first pass; your team reviews findings and decides what ships to the client. The difference is that your team starts from a completed checklist, not a blank page.

### How the Client Says Yes

Both tools let clients approve without creating an account. Pastel puts a "Finish Review" gate on every plan, including the free tier. The client follows a shared link, clicks through the page, and hits that gate to signal sign-off. It is a clean, low-friction moment that works well for straightforward projects.

Superflow's approval flow is built around the same shared-link idea, but the structure around it is different. Comments are pinned directly to the page, feedback is organized by status, and the client sees a clear view of what still needs attention before signing off. Once they approve, that status is visible to the whole team immediately, with no one chasing a confirmation email.

For a single project with one round of feedback, the difference is minor. Where it shows up is in recurring work: Superflow's status tracking means your team always knows where approval stands across every active project, which is one of the sharper points of contrast in any [Superflow vs Pastel](https://usesuperflow.ai/comparisons/superflow-vs-pastel) comparison.

### Where You Review

Pastel wraps a pasted URL in a proxy canvas. That approach covers websites, images, and PDFs, and for agencies whose deliverables stay in that range, it holds up fine. Most [website feedback tools for agencies](https://www.designrush.com/agency/web-development-companies/trends/website-feedback-tools) share the same ceiling. There is no video support, no motion asset review, and no way to leave feedback on a Lottie file. If a client asks for notes on an explainer video or a branded animation, you are back to emailing timestamps.

Superflow installs as a snippet on your live site, with one-click setup for Webflow, WordPress, Framer, and Shopify. Beyond websites, the same workspace handles images, PDFs, video, and Lottie files, keeping the same pinned comments, same status tracking, and same approval flow across every asset type. Tools compared as [Markup.io alternatives for agencies](https://usesuperflow.ai/alternative/markup-alternative) often run into the motion-asset gap too, so the distinction is worth checking before you commit.

If your agency works strictly in the website and PDF lane, the difference is minor. If motion assets ship alongside web builds regularly, having one tool cover all of them matters.

### What Stays Private

Pastel does not have a private comment mode. Any comment left on a review is visible to everyone with the shared link, including the client. That works fine when your internal notes and client-facing feedback are the same thing, but that is rarely true. If a designer flags a concern about a client's copy choice, or the team needs to talk through a scope issue before a client sees it, there is no way to keep that conversation internal without switching tools.

Superflow separates internal and client-facing views by design. Private comments mode keeps team notes visible only to the internal team, while guest mode controls exactly what the client sees. The two views do not bleed into each other. Your team can flag something, discuss it, resolve it, and the client never sees the thread. That separation matters most on projects where the team needs room to think before the client gets involved, which is most projects.

### What Gets Captured

Every comment in Pastel auto-captures a screenshot along with browser and screen size metadata. That gives reviewers useful context for reproducing a bug, but it stops there. There is no audit trail, and no compliance certifications appear in Pastel's public documentation.

Superflow logs every comment, AI finding, and approval in a full audit trail. On the compliance side, Superflow holds SOC 2 Type II, HIPAA with BAA, SAML/SSO, SCIM provisioning, and data residency options. Enterprise accounts get a 99.999% uptime SLA. That documentation matters when a procurement or legal team asks for a SOC 2 report or a signed BAA before a contract moves forward, a situation covered in the [Pastel vs Ruttl](https://usesuperflow.ai/comparisons/pastel-vs-ruttl) comparison for compliance-driven clients. Pastel cannot produce that paperwork. Superflow can, and [Superflow vs Usersnap for agencies](https://usesuperflow.ai/blog/superflow-vs-usersnap-for-agencies) shows how that gap plays out across similar tools.

### What It Remembers

Pastel has no per-client memory. Every review cycle starts from scratch. There is no place to store a client's brand guide, standing checklist, or feedback from the last three projects. If a client has a rule about button copy, someone on your team has to remember it and check it manually every time.

Superflow's Memory changes that equation. You upload a brand guide and checklist once per client, and Memory builds on every review round after that, learning the client's rules, preferences, and past decisions. That knowledge feeds directly into the AI agents, so checks become more client-specific over time. Memory is scoped per account, so rules from one client never bleed into another's review. By the tenth project, agents already know what took the first project three rounds to establish.

### How It Fits Your Stack

Pastel exports comments to PM tools as a one-way push. Once those comments leave Pastel, they are static. There is no live sync, no API, and no webhooks. If a task gets updated or closed in Asana, Pastel does not know about it. For a small project with one feedback round, that is manageable. Across multiple active clients it creates reconciliation work that adds up fast.

Superflow connects two-way to Asana, Monday.com, ClickUp, Trello, and Jira. Comments create tasks; sign-offs close them; status stays accurate in both places without anyone manually updating either side. Slack, email, and WhatsApp notifications keep the right people informed at each step, and a REST API with webhooks covers any custom workflow your team has built around its existing tools.

## Side-by-Side Comparison

| Criteria | Superflow | Pastel |
| --- | --- | --- |
| Who checks the site | AI agents run accessibility, broken links, spell check, and OG image checks automatically on every site change; your team reviews findings, not a blank page | A human reviewer spots issues manually and types each one out; nothing is checked unless someone notices it |
| How the client says yes | Client clicks a shared link, no login or account required; structured status tracking shows exactly where approval stands | "Finish Review" gate on all plans including the free tier; clients need to follow a shared Pastel link |
| Where you review | Live site via a snippet install (one-click for Webflow, WordPress, Framer, Shopify); also supports images, PDFs, video, and Lottie files in the same workspace | Proxy canvas wrapping a pasted URL; covers websites, images, and PDFs only, with no video or motion asset support |
| What stays private | Private comments mode keeps internal team notes separate from the client-facing view; guest mode controls exactly what clients see | No private comment mode; all comments are visible to anyone with the review link |
| What gets captured | Every comment, AI finding, and approval is logged in a full audit trail; SOC 2 Type II, HIPAA with BAA, and data residency options for compliance-bound clients | Each comment auto-captures a screenshot with browser and screen size metadata; no audit trail, no compliance certifications in public documentation |
| What it remembers | Memory stores brand guides, checklists, and past decisions per client; agents get smarter on every project and rules never bleed between accounts | No memory or per-client context; every new review starts from scratch with no knowledge of prior feedback or brand rules |
| How it fits your stack | Two-way sync with Asana, Monday.com, ClickUp, Trello, and Jira; Slack, email, and WhatsApp notifications; REST API and webhooks for custom workflows | One-way comment export to PM tools; no live sync, no API, no webhooks, so once comments leave Pastel they are static |

## Why Superflow Is the Better Choice

Pastel earns its reputation. For freelancers and small teams running simple feedback on websites or images, the zero-install approach and built-in approval gate get the job done without asking anyone to learn a new tool.

Run through all seven criteria in the comparison table, though, and the gaps compound. Who checks the site: a person, manually, every time. How the client says yes: a shared link with no structured status tracking. Where you review: websites, images, and PDFs only. What stays private: nothing, since all comments are visible to anyone with the link. What gets captured: a screenshot and some metadata, with no audit trail and no compliance certifications. What it remembers: nothing; every review starts from scratch. How it fits your stack: a one-way comment export that goes static the moment it leaves Pastel.

None of those are features waiting to ship. No AI checks, no private comments, no per-client memory, no audit trail, no SOC 2 or HIPAA documentation, and no live PM sync sit outside what Pastel is built to do. For a single freelancer running a homepage refresh, that range is fine. For an agency managing recurring QA cycles across multiple clients, shipping video or Lottie files, or working with buyers who route vendor approvals through legal or procurement, those gaps become blockers fast.

Superflow covers all seven criteria: AI agents run the first QA pass automatically, private comments keep internal notes separate from client view, memory stores brand rules per client, every comment and approval lands in a full audit trail backed by SOC 2 Type II and HIPAA with BAA, and two-way PM sync keeps task status accurate without manual reconciliation. Looking at [Pastel alternatives for agencies](https://usesuperflow.ai/alternative/pastel-alternative) is worth the time before those gaps become the reason a project stalls.

## Final Thoughts on Superflow vs Pastel

Pastel is a solid tool for what it does. The limits only show up when your workflow outgrows it. If your agency is running QA across multiple clients, delivering video, or working with compliance-conscious buyers, Superflow is worth a closer look.

## FAQ

### Should my agency use Superflow or Pastel if we're running QA across multiple active client projects?

If your team is managing recurring QA cycles across several clients, Superflow is the better fit. AI agents run checks automatically on every site change, and two-way sync with tools like Asana, ClickUp, and Jira keeps task status accurate without manual reconciliation. Pastel's one-way comment export works for a single project but creates real overhead at scale.

### What is the core difference between how Superflow and Pastel handle QA reviews?

Pastel captures feedback that a human notices and types out. Superflow runs AI agents on every site change that check for accessibility issues, broken links, spelling errors, and OG image problems before anyone on your team opens the page. Your team reviews findings instead of conducting the search themselves, which changes how long QA actually takes.

### Who is Pastel best suited for, and where does Superflow become the right choice?

Pastel is a good fit for freelancers and small agencies running straightforward feedback cycles on websites, images, or PDFs where setup speed matters more than workflow depth. Superflow is built for agencies that ship motion assets like video or Lottie files alongside web builds, serve clients with compliance requirements, or need PM integrations that stay live in both directions.

### Can Superflow meet enterprise compliance requirements that Pastel cannot?

Yes. Superflow holds SOC 2 Type II, HIPAA with BAA, SAML/SSO, SCIM, and data residency options. Pastel has none of these certifications in its public documentation, which makes it unsuitable for compliance-bound clients where procurement or legal will ask for that paperwork.

### How long does it take to get Superflow's AI agents running on a client site?

Setup takes four steps and requires no engineer. You add a snippet to your site (or use the one-click install for Webflow, WordPress, Framer, or Shopify), paste in your QA checklist or upload a brand guide, and the agents start running checks and posting findings automatically. Most teams are live within a single work session.
