If leaving means exporting a flat file, you never owned the suite. Self-hosted Tesbo is the whole product on your box: Context Engine, review queue, nested suites, runs, reporting. Same code as cloud.
Generic AI test cases fail quietly. They look right, they read fluently, they reference a flow that almost matches yours. Indexed context is how you get "almost" out of the test suite.
With the Tesbo Playwright Reporter, a Playwright run creates a Run in Tesbo and stores each result against it. Manual results and automated results land in the same history. The intelligence layer sits on top of both.
Open source with self-host isn't a licence tier for us. It's the answer to "where does my test data live." On your infra, if you want it. Apache 2.0, readable code, your database.
A confidently written test case can still describe a feature that doesn't exist. That's what generic AI produces from a blank prompt. The fix isn't a smarter model. It's a model that read your product first.
Execution and record-keeping are different jobs. Playwright is good at the first. A test manager should be good at the second without pretending to do the first.
The vector index is the part people forget. It's where the AI's understanding of your product lives. Self-host means that index sits next to your Postgres, not inside someone else's SaaS.
Tesbo's Context Engine reads before it writes: requirements, documentation, defect history, existing suite. Then it drafts with citations. Then a person signs. Remove any one step and you're back to generic AI.
One run record for manual and automated. If the automated half is only in a CI artifact that expires in 30 days, your release evidence has a half-life.
"Your context never leaves your infrastructure" is a deployment fact, not a slogan. git clone, docker compose up -d, Postgres and the vector index come up on your box. Nothing phones home.
Prompting harder doesn't add knowledge. A better prompt gets a more confident guess about a product the model has never seen. Indexing the requirements, docs, defects and suite first is what adds knowledge.
Tesbo doesn't run your Playwright tests. Your runner, your CI, your framework stay yours. The Tesbo Playwright Reporter sends the result back so the run shows up in the same history as the manual pass.
Requirements, defect history, the way your senior tester writes a step. That's not data. That's the context your whole suite was built from. Self-hosted Tesbo keeps it on infrastructure you run.
A generic model asked for login tests gives you login tests. Not your login. Not the SSO fallback your team added in March, not the lockout rule from the defect last quarter. It never read any of that.
Your automation results live in CI logs. Your test cases live in a test manager. Nobody can answer "what did we actually verify for this release" without opening both and doing the join by hand.
AI drafts. QA keeps the judgment. Every week that line gets tested by a new "autonomous QA" launch, and every week the teams that kept the review step are the ones not debugging phantom test cases.
Moving off a spreadsheet doesn't need a migration project. Tesbo imports CSV and XLSX and keeps nested suites intact. Import the file. Review the structure. Run.
Replace the question. Not "will AI replace QA" but "what does QA get to stop doing." Writing the fifth variation of a login test by hand is a good place to start.
