Pricing
FreemiumRegression 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.
CustomKeywords Studios operates exclusively on custom enterprise contracts — there are no public self-serve pricing tiers or monthly subscription plans.
Pricing is project-based and depends on the scope of services required: QA testing engagements, localization projects (per word/language), game development co-production agreements, audio production, art services, or player support contracts are all scoped and quoted individually.
Studios and publishers engage via Keywords' global sales team. Given Keywords' scale (70+ studios, 13,000+ staff), it typically serves mid-size to AAA publishers — though smaller studios may engage for specific targeted services like QA or localization.

End-to-end game services with AI-powered QA, localization, development, and player support for game studios worldwide
Regression Games Pros & Cons
Pros
- Genuinely differentiated focus on AI agents and bots purpose-built for the Unity ecosystem
- Lightning-fast integration model requiring only a few lines of code to plug into existing game logic
- Smart replay and deep state capture go well beyond simple macro-based test recording
- No-code functional testing builder lowers the barrier for teams without dedicated QA engineers
- Backed by respected VCs (NEA, a16z), signaling credibility and staying power in the AI gaming space
- Free tier lets teams evaluate the platform with zero upfront cost before committing
Cons
- Purpose-built for Unity, so studios using Unreal Engine, Godot, or custom engines can't use the core SDK
- AI Agent Marketplace for community-shared bots is a newer addition, so the shared bot library is still growing
- Best suited to teams with dedicated QA or gameplay engineering needs; very small solo projects may find it more infrastructure than necessary
- Deeper automated testing setups (chaos testing, bot sequences, CI/CD pipelines) require some engineering investment to configure well
- Public pricing details beyond the free tier are less transparent, often requiring a demo conversation for paid plan specifics
