testRigor alternative: agents that use your app

testRigor has a free plan, but its sign-up page says every test and result on that plan is public. Private work needs the Private plan, which shows a two-week trial and no price, or Enterprise at custom pricing. People look elsewhere when they want to try agents on a link without choosing a plan first, when they want public prices, or when the question is how a newcomer experiences the app rather than whether written steps still pass.

• testRigor: tests written in plain English and kept as a suite, for web, native and hybrid mobile, desktop and API.
• Mimiq: no suite to keep. Agents try a task as different users, about 5 to 15 minutes for 5 agents.
• testRigor: a free plan with public tests and results, a two-week private trial, and custom enterprise pricing.
• Mimiq: first test free, then a $9 Starter (120 credits that never expire) or monthly plans from $19.
• Both: tests start from plain words, and both list an MCP server for coding agents.

testRigor calls itself an AI-based test automation tool for end-to-end UI testing. You write steps in free-flowing plain English from the end user's point of view, such as "purchase a Kindle", and it translates them into specific actions. Tests can be written in the tool, generated through an AI coding tool over MCP, or built by importing manual test cases from a test management tool such as TestRail, and you review and refine the generated steps. Its features page lists web (desktop and mobile browsers, with more than 3,000 browser, device and operating system combinations), native and hybrid iOS and Android apps, native desktop apps (paid versions only), API, email, SMS and phone call checks, and two-factor logins.

It lists CI integrations with GitLab, GitHub Actions, Jenkins, Azure DevOps and CircleCI, and results can go to Jira, TestRail, Slack, Microsoft Teams and email. Its docs index includes an MCP server page and a guide to writing, running and maintaining its tests with Claude Code. Its homepage says tests will not fail unless functionality changes and that it groups related failures so they can be fixed together; those are the vendor's claims.

Pricing is partly public. Its sign-up page shows three plans: Free, free forever, on which all tests and results are public and can be shared by link; Private, which shows a two-week trial and no price; and Enterprise at custom pricing.

Mimiq sends AI agents to use your web app. You paste a link and give a task in plain words, such as "Sign up and start using it". Each agent opens the app in its own real browser, plays a person with a reason to be there, and works toward the task for up to 40 steps. The report shows what broke (errors on screen, buttons that do nothing, forms that reject good input, dead ends), what the browser caught on the site (JavaScript errors, requests that failed or answered 4xx or 5xx, and requests slower than 3 seconds, ranked by how many agents hit each), and where each agent got stuck or gave up and why, in its own words, with the step and a screenshot. The problems are ranked, with suggested fixes.

You can run it by pasting a link in the app, from a coding agent through the MCP server at mcp.mimiqai.com (Claude Code, Cursor, Codex, VS Code and Windsurf), or on every preview deploy with the GitHub Action github.com/victorgulchenko/mimiq-preview-check, which works with Vercel, Netlify and Cloudflare Pages previews, leaves one pull request comment and can fail the check. Agents get a working inbox for verification codes. With paid credits they can also sign in with a test account and open protected previews, using a Vercel bypass secret or basic auth.

Mimiq does not write or export test scripts, does not test native mobile apps, and does not predict how many real people will finish. Every agent is simulated, agents choose their own paths so two runs can differ, and a run is not exhaustive. Agents cannot pay with real cards, and a CAPTCHA can stop them.

Both start from plain words. The difference is what the words become. In testRigor your sentences become test steps that are saved and rerun, so you learn whether the paths you chose still work on the browsers, devices and operating systems you run them on.

In Mimiq a sentence such as "Sign up and start using it" is a goal handed to agents, not a list of steps. Mimiq keeps no suite. Each run is a fresh set of agents, each playing a person with a reason to be there, and the report is about their experience: the errors and slow requests the browser caught, where one gave up and why in its own words, and wording that sent a newcomer the wrong way. A saved test checks the outcome it names; it does not tell you that a newcomer would not understand a step.

Neither is exhaustive. testRigor's coverage is the tests someone has written or imported. Mimiq runs vary, because agents choose their own paths, and Mimiq does not export a script you could rerun.

Choose testRigor when you need native iOS or Android, desktop or API tests, which Mimiq does not do, when you want a maintained suite that runs from CI, or when manual QA staff will own the tests: its homepage is built around putting manual QA and QA engineers on one platform. Its free public plan also works if your tests can be public.

Choose Mimiq when you have a link or a preview and no suite yet, when you want a first read in minutes without a call, when you want public prices, or when you want agents built from your own customers on a staging build.

Mimiq pricing is public: the first test is free with a free account (Google sign-in, no card), and the account includes 50 credits. An agent uses 5 credits, so 5 agents use 25. After that it is a $9 Starter (120 credits that never expire) or monthly plans from $19. Mimiq is not a regression suite. If the same checks must run the same way on every release, testRigor or a scripted suite is the right tool.
