Prufa alternative: Sybqa vs Prufa
First published · Facts checked · Updated
Short answer
Choose Prufa if you want a no-signup free audit, verified vs advisory grading, paid continuous monitoring, or an MCP tool your coding agent can call. Choose Sybqa if you want a reviewed plan before anything runs, phone and narrow layout checks with axe-core in the same report, and a free monthly run allowance after signup. We have not run Prufa.

Context and limits
Prufa and Sybqa both start from a URL and drive a real browser without asking you to write a test suite. Prufa’s public pages describe an AI agent that navigates and a plain-code harness that grades captured evidence into six A–F sections, with verified machine findings separate from advisory LLM notes. Sybqa generates a plan you review, then reports evidence at desktop, phone and narrow widths. We make Sybqa, so weigh this page accordingly.

At a glance
| Point | Sybqa | Prufa |
|---|---|---|
| Core job | Explores approved journeys for bugs, UI inconsistencies and UX flow issues using manual-testing techniques and real browser checks | AI QA engineer: agent navigates a live app; plain code grades network, console, cookie and status evidence |
| Where you start | A link and an optional goal. You review the plan before anything runs | Paste a public URL (no signup for the free audit) or call prufa_run_audit over MCP / HTTP API |
| What you get back | An evidence report (HTML, JSON and JUnit) with available screenshots and recorded steps; blocked and not-run checks are listed, never counted as passed | Six graded sections (works · fast · found · measured · accessible · compliant); verified vs advisory findings; shareable HTML/JSON report |
| Public pricing | A free plan after signup (10 runs a month, no AI review) and a paid plan with AI credits | Free $0 audits forever. Starter $29/mo (500 runs, 3 sites). Pro $99/mo (5,000 runs, 10 sites, MCP). Team $179/mo (50,000 runs, unlimited sites, 5 seats) |
| How usage is counted | Runs without AI review use no credits; AI review uses the plan’s credits | One LLM call in the agent loop is one run; deterministic replays of confirmed flows meter zero |
| Pipelines | Start a saved plan from GitHub Actions, GitLab CI, Bitbucket Pipelines, CircleCI or any CI with an API token (guide) | Deploy webhook and GitHub Action on paid monitoring; MCP and OpenAPI for agents |
Which one to choose
Choose Sybqa if
- You want to review a generated plan before the browser runs.
- You want desktop, phone and narrow widths plus accessibility rules in one evidence report.
- You want a free monthly run allowance after signup rather than only a one-shot free audit.
Using both is reasonable: Prufa for a fast anonymous pass or agent loop, Sybqa when you want a reviewed release check you can retest after a fix.
What this comparison does not claim
We make Sybqa. We read Prufa’s public home, pricing and MCP pages on the date shown under Sources. We have not run Prufa, so this page makes no claim about which tool finds more bugs or grades more accurately. Prufa’s free audit is described as read-only on public pages and not submitting forms; confirm current behaviour on their site.
Common questions
Does Prufa require an account for the free audit?
Prufa’s home and pricing pages say the free audit needs no signup and no card. Paid Starter, Pro and Team plans start with a 7-day trial that asks for a card up front.
Can a coding agent drive Prufa?
Yes. Prufa documents an MCP server and prufa_run_audit / prufa_get_report tools, plus an HTTP API and OpenAPI contract. Sybqa’s hosted builder-chat MCP is a separate product surface with its own security gate.
