assrt.net vs assrt.ai: which one did you mean?

Two sites share the assrt name and have nothing to do with each other. One is a subtitle download community that has been around for years. The other is a developer testing tool. Search engines blur them together because of the shared letters, so here is the fast answer, then the part that matters if you actually wanted the testing tool.

Telling the two apart

The simplest way to know which one you landed on: look at what the site is for. They do not overlap in any way.

If subtitles are what you need, stop here and head to assrt.net. The rest of this page is for the people who meant the testing tool.

If you meant the testing tool: what assrt.ai does

assrt.ai exists because writing end-to-end tests is tedious and maintaining them when the UI changes is worse. Most teams either skip testing or sink hours into brittle selectors. Assrt crawls your app, discovers scenarios, and generates real Playwright tests you keep in your own repo. The tests are standard files, not a proprietary format, so there is nothing to be locked into.

The part you can verify: a plan is just #Case blocks

You do not record clicks into an opaque recorder. You write a plan in plain English, where each test is a #Case: block. Every block runs as an independent scenario inside one shared browser session, and an LLM agent (Claude Haiku by default) interprets the steps, drives the page with Playwright, and reports a result. Each run also writes a real .webm recording to disk, so you can watch exactly what the browser did.

Run that with npx @m13v/assrt run --url http://localhost:3000 --plan "..." and each #Case comes back pass or fail with a recording attached. The source for all of this is public at github.com/assrt-ai/assrt-mcp, so the behavior described here is checkable, not a marketing claim.

Why developers pick it over the alternatives

The closed tools in this space charge real money and hand you a format you cannot leave. QA Wolf runs around $7.5K a month and is closed-source. Momentic uses proprietary YAML and is Chrome-only. assrt.ai outputs the same standard Playwright code in any of the three browser engines, runs in your own CI, and costs nothing. When you want to walk away, you keep the tests, because they were always just files in your repo.
