Chorus is free. Bring your own Anthropic API key and pay only for what you use — typically $1–5 to build an entire app. Free credits included so you can see the power for yourself.
Create your account with GitHub. You get free credits immediately — enough to build your first project and see what Chorus can do.
When you're ready to keep building, plug in your own API key. Takes 60 seconds. You pay Anthropic directly — no markup from us.
Most apps cost $1–5 total in API usage to build from scratch. Ongoing feedback-driven improvements cost a few cents each.

No add-ons. No upsells. No “contact sales for this feature.”
Most AI app builders charge you a subscription, then use their API key behind the scenes. They buy API access wholesale and sell it to you at a 5–20x markup. You can't see how much the AI actually costs. You just see opaque “credits” disappearing.
Chorus is a platform that facilitates building. We provide the orchestrator, the agent team, the feedback loop, the quality gates, and the deployment pipeline. But the AI itself? That's powered by your Anthropic API key.
You pay Anthropic directly, at their published rates, with zero markup from us. Chorus never touches your token costs. We're the facilitator, not the middleman.
This gives you full transparency. Every API call, every token, every cent shows up in your Anthropic dashboard. When you build an app for $3, you can verify exactly where that $3 went.
It also aligns our incentives. Since we don't profit from your token usage, we're motivated to make the orchestrator efficient — to build your app in fewer messages, not more. Other tools profit when the AI struggles. Every debugging spiral is revenue for them. With Chorus, it's just waste we're incentivized to eliminate.
Chorus is a platform that facilitates building — we provide the orchestrator, the AI team structure, the feedback loop, and the deployment pipeline. The actual AI processing is powered by your own Anthropic API key. You plug it in, we use it to run your AI agents, and you pay Anthropic directly for usage. Chorus never marks up or touches your API costs.
The Chorus platform is free (or $49/mo for Pro features). The AI usage — which you pay directly to Anthropic through your own API key — typically costs $1-5 to build an entire app from scratch. Ongoing improvements from user feedback are even cheaper, usually a few cents per change. You can see every cent in your Anthropic dashboard.
Every new Chorus account gets free credits to explore the platform and build your first project — no API key needed. Once you're ready to keep building, getting an Anthropic key takes about 60 seconds at console.anthropic.com.
Everything except the raw AI processing: the multi-agent orchestrator (Lead, Dev, QA, Design, Analyst), the feedback widget, quality gates (type checking, tests, deploy verification), GitHub/Vercel/Supabase integration, the deployment pipeline, project management, and the continuous improvement loop. Your API key provides the AI brainpower; Chorus provides the system that makes it useful.
Yes. Everything lives in your GitHub account, deploys to your Vercel account, and uses your Supabase database. If you stop using Chorus tomorrow, your apps keep running. Standard Next.js + Supabase — any developer can work with it.
Your apps run on free tiers of Vercel and Supabase, which are generous (Vercel Hobby is free, Supabase free tier includes 2 projects with 500MB each). If your app grows beyond free tier limits, you upgrade with those providers directly.
Lovable charges $25/month for ~150 opaque "credits." Bolt charges $25/month for 10M tokens. Both mark up the underlying AI cost 5-20x and hide it behind proprietary units. With Chorus, the platform is free, and you pay Anthropic directly at their published wholesale rates — no markup, full transparency. A full app that would burn through a month of Lovable credits costs $2-4 in direct API usage on Chorus.
Yes. No contracts, no lock-in. Your apps run on your own Vercel + Supabase infrastructure, so they keep running forever regardless of what you do with Chorus.
