Rosebud AI

Inworld AI

Pricing Model

FreemiumRosebud AI offers a free tier that includes a limited weekly allowance of prompts (reported around 20 prompts per week for continued access to existing projects) for creating and playing games, with no commercial usage rights and no code access. Paid plans sit above the free tier, including a Pro plan (third-party trackers report pricing around $19/month) and a higher "10x Dev" tier, both of which unlock significantly more AI generations, larger and more complex projects, direct access to edit the underlying generated code, and full commercial usage rights, letting creators sell games and assets with 100% of profits retained and no commission taken by Rosebud. Compute-heavy tasks like 3D rendering and complex animations can consume additional "Spark Credits" on top of a subscription for heavier projects. An Enterprise tier exists for organizations needing team management and collaboration features not available on individual plans. Because Rosebud adjusts pricing and credit allowances as its underlying model costs change, the live pricing page under "My Plan" on rosebud.ai is the most reliable source for exact current figures.

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. Unused subscription credits roll over for up to 3 months, and LLM usage through the Realtime Router is billed at provider cost with no markup.

Rosebud AI Pros & Cons

Pros

Genuinely free to start, with no download or installation needed to create or play games
Generates code, art, and sound together in one flow, rather than requiring separate asset-store shopping
Real, editable JavaScript code on paid plans means it's not a fully locked black box
100% of profits retained by creators on commercial plans, with zero commission taken by Rosebud
Backed by a decade-old team with real Y Combinator and VC credibility (Jeff Dean, Adam D'Angelo as early backers)

Cons

Games are published as browser links only; there's no way to export a standalone build for Steam or offline distribution
Free tier's weekly prompt/credit allowance is easy to burn through once you start iterating on a real project
Complex bugs often need manual code intervention since AI debugging isn't always reliable on the first try
No team collaboration features outside the Enterprise tier, making it a solo-creator tool for most users

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
