OpenUser: Self-Hosted User Testing for AI Agents

Developers building AI agents need to test them against real user workflows, but existing solutions like TestSprite aren't self-hostable. OpenUser lets you run automated user persona tests on your codebase locally, simulating real user interactions to catch bugs before production. Target: B2B/SaaS developers using AI agents for feature testing.

AI agent testing is a genuine gap right now — most QA tooling predates agentic workflows and can't simulate the nondeterministic, multi-step behavior these systems produce, so developers are either skipping structured testing or hacking together fragile scripts. TestSprite is the closest named competitor but lacks self-hosted deployment, which matters acutely to teams in regulated industries or those unwilling to pipe production-adjacent data through a third-party SaaS. The $2k–10k/mo band is plausible for a devtools product with a self-hosted tier, though it implies landing mid-market teams willing to pay for support or an enterprise wrapper — pure open-source without a clear commercial layer will stall there. The biggest risk is that AI agent behavior is hard enough to define that "simulating real user interactions" becomes a moving target, leaving the product perpetually one model-version behind and making reliable test assertions nearly impossible to standardize.
