Regression Games

Regression Games is an AI agent platform purpose-built for Unity, letting game developers build and deploy bots for QA testing, NPCs, multiplayer scenarios, and game balancing without the heavy engineering lift traditional test automation usually requires. Founded in 2022 by Aaron Vontell and backed by NEA and a16z, the Philadelphia-based company set out to make AI-driven gameplay and automated testing accessible to teams of any size, from solo indie developers to full QA departments.

The platform's Unity SDK integrates into a project's existing game logic with just a few lines of code, giving bots the ability to interpret game state and take real actions: clicking through menus, controlling spawned characters, play testing alongside human players, and validating specific behaviors. Its smart replay and playback system goes beyond simple macro recording, capturing screenshots, logs, and performance data to give teams deeper insight into what actually happened during a test run. A no-code functional testing builder opens automated testing up to teams without dedicated engineering resources, while exploratory bots like the Monkey Bot uncover edge-case bugs that scripted tests would miss entirely.

Regression Games is best suited for Unity studios that want to replace time-consuming manual QA with automated, CI/CD-integrated bot testing, as well as teams exploring AI-driven NPCs and multiplayer bot behavior. Ready-to-go bot templates for genres like match-3 puzzles, MOBA/RPG ability validation, and FPS/multiplayer NPCs help teams get started quickly, and a free tier makes it easy to try the platform before committing to a paid plan.

Regression Games offers a free tier that provides access to the Unity SDK, core bot-building tools, and ready-to-go templates at no cost, making it straightforward for individual developers and small studios to get started. Beyond the free tier, pricing for advanced features and larger studio deployments is not fully published; prospective customers can book a demo directly through the Regression Games website to discuss plan options suited to their team size and testing needs.
