For vibe coders & AI builders

AI can build it.
Only humans
can break it.

You shipped something with AI. Now find out if real humans can actually use it — before your users tell you with silence.

Built for vibe coders · Real testers. Real signal. · Not your friends. Not Reddit. · Structured feedback every time

Posting online is too noisy.
Asking friends doesn't work.

Social media

You post. You get 48 hours of traffic, a few "nice!" comments, then silence. No one tells you why they left.

Friends & colleagues

They're too polite. "Looks great!" doesn't tell you why users drop off on step 2 or can't find the sign-up button.

User research firms

Weeks of scheduling, thousands of dollars, and a PDF you'll read once. You just need a real person to click around.

Submit. Go live. Get signal.

From submission to your first review in under 24 hours.

01
Submit your build

Drop your URL and write a mission brief — what you want testers to actually do. 11 automated safety checks run instantly. A human admin approves within 24 hours.

02
Go live on the Pulse

Your project appears on the global Pulse — a live globe of active builds. Your position on the Ladder is determined by the pack you chose. Launch Pack sits at the top, Signal in the middle, Starter at the base. Higher position means more testers see you first.

03
Testers run your mission

Each tester actually uses your product — minimum 60 seconds — then fills in a structured form. Friction points, magic moments, star rating, and a summary. No fluff. No "looks nice!"

04
Read your reviews. Ship faster.

Reviews appear in your dashboard. Friction points show you where users struggled. Magic moments show you what to double down on. Tier 3 also gets an AI analysis pass across all your feedback.

Real testers who can do the actual thing

Jellar testers are builders themselves — they use the same tools you do. If your app requires a login, they have an account. If it uses OAuth, they can connect it.

GitHub OAuth

Testers can log in with GitHub. Common for dev tools, dashboards, and API products.

Google OAuth

Google sign-in works. Testers can connect Google accounts where required.

Twitter / X OAuth

Social login with X. Testers can authorise apps that require a connected X account.

Email sign-up

Testers use test credentials — not their real email — when your app requires a new account sign-up.

Free plan features

Testers can explore and test free tiers of your product. Paid-only features should be noted in your mission brief.

Web apps only

Jellar currently tests web-based projects only. iOS and Android native app testing is on the roadmap.

One rule testers always follow: they never enter real financial information or sensitive personal data into test projects. Design your mission brief with this in mind.

Structured. Specific. Actionable.

Every review follows the same format — so you're comparing apples to apples across testers. No blank-page reviews. No one-word answers.

Friction points tell you where users got stuck. Magic moments tell you what's working. The one-change field forces testers to prioritise — which means you know what to fix first.

Mission completed ✓
★★★★☆
Friction point

"Sign-up button wasn't visible on mobile — had to scroll way down. Nearly gave up."

Magic moment

"The onboarding checklist was genuinely satisfying. Kept me going."

If I could change one thing

Mission completed ✓
★★★☆☆
Friction point

"Couldn't figure out how to export. No obvious button and the help link 404'd."

Built specifically for how vibe coders work.

You build fast with AI. You need feedback just as fast — from real humans who actually try to use it.

Real accounts only

GitHub OAuth only. No anonymous feedback. Every review is traceable to a real person — which means accountability and signal you can trust.

60-second minimum dwell

Testers must spend at least 60 seconds with your build before they can submit. No skimming. No guessing. Actual usage.

Structured every time

Friction points, magic moments, expectation vs reality, one-change field. Same format every review. Comparable, consistent signal.

Safety checked

11 automated checks plus human admin review protect testers. Means the community trusts the platform — which means more testers for you.

Built for fast iteration

Listings expire by pack (14–30 days) so the platform stays fresh. Buy a new pack when you ship a new version and get a fresh round of reviews.

AI analysis on Signal + Launch

Get an AI-assisted summary across all your feedback sessions — patterns, contradictions, priority fixes. Human testing plus AI synthesis, included in Signal and Launch packs.
