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.
FreemiumInworld AI uses a credit-based subscription model with a free On-Demand tier for evaluation and prototyping, including up to 70 minutes of TTS or 400 minutes of STT at no cost, with 100 custom voices and full Realtime API access under a commercial license.
Paid plans start with Creator at $25/month (up to 33% off base rates), Builder at $100/month (up to 40% off, workspace sharing), Developer at $300/month (up to 47% off, priority email support), and Growth at $1,500/month (up to 53% off, 30,000 custom voices, HIPAA and BAA add-ons). Realtime TTS-2 pricing ranges from $25 per million characters on-demand down to $12.50 on the Growth plan, with Realtime TTS-2 Flash starting at $15 and falling to $7.
Enterprise pricing is fully custom, with Realtime TTS-2 rates as low as $5 per million characters, price-match guarantees, SLAs, EU and India data residency, and a dedicated account manager.

Summary
AI agent platform for building Unity bots for QA testing, NPCs, and multiplayer
Realtime TTS, STT, and LLM routing infrastructure for consumer-scale voice AI
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
Inworld AI Pros & Cons
Pros
- Realtime TTS consistently ranks #1 on the Artificial Analysis Speech Arena in blind user tests
- Significantly cheaper than comparable providers like ElevenLabs and Deepgram at scale
- Single API and WebSocket connection covers STT, LLM routing, and TTS together
- Provider-agnostic LLM routing avoids vendor lock-in and lets teams swap models anytime
- Enterprise-grade compliance built in, including SOC 2 Type II, HIPAA, and GDPR
Cons
- Full pricing benefits require higher-tier paid plans, which may be costly for very small projects
- Advanced compliance features like HIPAA, BAA, and zero data retention are gated behind add-ons or Enterprise
- Professional voice cloning is only available from the Developer plan and above
- Some capabilities like WebRTC and SIP transport are still in early access rather than general availability
