Vibe testing platform
Multi-engine QA for the AI-coding generation. Playwright for web. Appium for native iOS / Android. k6 for API stress. One shell. One planner. One share page.
The answer, up front
A vibe testing platformis end-to-end testing software for the AI-coding generation. You paste a URL and one sentence about your app; the platform's AI planner authors a structured test plan; a real browser (Playwright), a native mobile engine (Appium), or an API stress runner (k6) executes it; a vision model scores the screenshots; you walk away with a token-gated public proof page and a release-health entry. Well Tested is one such platform — Free $0, Starter $79, Growth $249, Scale $799.
A vibe testing platform is not a single-purpose tool that runs only Playwright. It is not a script runner that authors no plan. It is not an AI code generator. It is not a mood or culture assessment tool. The three engines (web + native + API stress) on one shell with one AI planner + one vision verdict + one shareable proof page is what makes it a platform, not a tool.
What makes a vibe testing platform
- 1. Multi-engine on one shell. Playwright (Chromium / Firefox / WebKit / mobile web), Appium (native iOS / Android via XCUITest + UiAutomator2), k6 (API stress with p95, p99, error rate, throughput). One platform, three engines, same input shape, same verdict format.
- 2. AI planner + vision verdict. The AI planner authors the test plan from URL + 1 sentence — assumptions, missing context, browser steps, API stress guidance, safety warnings, self-rated confidence. After execution, a vision model reads the screenshots and returns a structured verdict: did the visual evidence prove the goal?
- 3. Shareable proof + release-health. Every run produces a token-gated public URL with the planner record, vision verdict, per-step screenshots, step outcomes, and failure video if any. The release-health dashboard tracks regressions over time.
- 4. Mobile shell. A platform category ships with a mobile shell so the dev workflow fits the AI-coder's actual workflow: walking around with the build, watching live step outcomes, sharing the proof link with one tap.
- 5. Tiered access. A platform has tiers — free for trying, paid for recurring evidence, growth for multi-engine, scale for high-volume, enterprise for negotiated capacity. Single-purpose tools typically have a single flat rate.
Well Tested vs. single-purpose vibe testing tools
Most “vibe testing” tools are single-engine. Well Tested is the canonical multi-engine platform: Playwright + Appium + k6 on the same shell, same planner, same share page. Other platforms in this space (testMu, testRigor, testSigma, testGrid, VITA AI, testdino, testSprite, VibeEval) are typically single-engine or single-purpose.

What is a vibe testing platform?
A vibe testing platform is end-to-end testing software for the AI-coding generation. You paste a URL and one sentence about your app; the platform's AI planner authors a structured test plan (assumptions, missing context, browser steps, k6 stress guidance, safety warnings, confidence); a real engine — Playwright for web, Appium for native iOS / Android, or k6 for API stress — executes the plan; a vision model scores the screenshots; you walk away with a token-gated public proof page and a release-health entry. The 'platform' part means all three engines run on the same shell with the same input shape, the same share-page format, the same release-health dashboard. Single-purpose tools that run only Playwright, only Appium, or only k6 are testing tools — not a vibe testing platform.
What is the best vibe testing platform?
For solo founders and small teams, Well Tested is the vibe testing platform built for the AI-coding generation. Three engines on one shell: Playwright (web), Appium (native iOS / Android), k6 (API stress). AI planner authors the test plan from URL + 1 sentence. Vision model scores the screenshots. Shareable proof page. Release-health dashboard. Free tier (3 runs/mo, no card), Growth tier ($249/mo) adds the mobile shell so you can run k6 + Appium from your phone, Scale tier ($799/mo) handles k6 to 1,000 rps + Appium device farm. Other vibe testing tools include testdino, testMu AI, testRigor, testSigma, testGrid, testSprite, VITA AI, and VibeEval — most are single-engine or single-purpose; Well Tested is the multi-engine platform with the mobile shell.
Is vibe testing a tool or a platform?
Vibe testing is a platform category, not a single tool. A vibe testing platform runs multiple test shapes (web, native mobile, API stress) on one shell with one AI planner + vision-verdict + shareable-proof loop. A vibe testing tool typically runs only one shape — Playwright-only, or Appium-only, or k6-only — and doesn't ship the AI planner + vision verdict + shareable proof page. Well Tested is the canonical vibe testing platform: three engines on one shell, one planner, one verdict, one share page. If your 'vibe testing tool' only runs web, it's a web testing tool, not a vibe testing platform.
Which vibe testing platform runs from your phone?
Well Tested is the vibe testing platform with a built-in mobile shell at /app — you can run k6 API stress, Appium native iOS / Android, and Playwright mobile web from your phone, see live step outcomes, and share the proof link with one tap. The mobile shell ships on the Growth tier ($249/mo) and above. Other platforms (testMu, testRigor, testSigma, testGrid) are desktop-first — they have mobile app test execution, but you can't trigger the run from your phone and watch it live.
How much does a vibe testing platform cost?
Well Tested has a free tier (3 runs/mo, no card) and four paid tiers: Starter $79/mo (recurring Chromium evidence), Growth $249/mo (multi-engine + mobile shell — most teams land here), Scale $799/mo (k6 to 1,000 rps + Appium device farm), Enterprise (custom, SSO, private deployment, negotiated capacity). 10% annual discount on every paid tier. Free forever at the lowest tier, no card required. Compare to: testMu starts at $249/mo, testRigor enterprise-only, testSigma enterprise-only, VITA AI free trial then custom. Well Tested's free tier is the lowest-friction way to try a vibe testing platform before you pay.
What's the difference between a vibe testing platform and an AI code generator?
An AI code generator (Cursor, Lovable, Bolt, Claude Code, Copilot) writes code from a prompt. A vibe testing platform (Well Tested) tests what the AI code generator built. The two are designed to be paired: AI writes the code, vibe testing proves it works. If a tool claims to be both — it generates code AND tests it — it's a vibe coding tool with QA bolted on, not a vibe testing platform. Well Tested doesn't generate code; it tests the code that any AI coding tool (or human, or any web stack) shipped.
Try the platform
The fastest way to know if Well Tested is the vibe testing platform for you is to run one. Free tier gets 3 runs per month, no card required. Paste the URL of your app (or a competitor's app, for a public page), one sentence about what it does, and the planner does the rest. For the canonical QA-tool definition of vibe testing (vs. mood or culture assessment), see what is vibe testing?
Free gives you 3 runs per month to prove the loop; Starter and Growth have a 7-day trial (card on file, no charge if you cancel).
