Beneath the surface
A chat window forgets your files and stops when you close the tab. This keeps your files, runs on a schedule you choose, and can be reached from the internet. Direct it with the agent, or open the terminal yourself.

Direct it with AI. Open it yourself.

A few things to know
A ready-to-use home for your project: AI that can work on its code, a private Linux workspace, editable files, a browser terminal, persistent data and hosting for one live website or app. You can change how it works as well as how it looks. Choose your AI and open the same project from your phone or computer.
Launch is $29/month; Grow is $59; Scale is $99. Each is a complete workspace package with AI usage and hosting. Monthly AI usage is limited; further AI requests pause when the allowance is used. There is no automatic overage or refill. Domain registration, outside services and any checkout taxes are separate. Choose your plan and AI before signing in. Manage changes and cancellation in your account.
Your conversation gets a place to act. In a paid workspace, Build can inspect and change project files and run commands. You can open those same files and use the terminal yourself. Discuss helps you think without changing anything. Your work stays on the server between visits, and the published version stays live while you prepare the next code change.
Yes: an AI coding workflow with a managed Linux workspace, reached through your browser. OSP handles provisioning so you can get to the project. The terminal runs individual commands with a 30-second foreground limit; it is not a full interactive SSH session or a dedicated VPS. Python and Node apps can keep running after publication. See runtime details ↗︎
Choose Claude, OpenAI or DeepSeek in your paid workspace. Discuss uses a lower-cost model; Build uses a capable coding model. Changing AI keeps your project. Gemini is wired into the free experience but still needs provider activation; it is not advertised as ready in the paid workspace. These are metered APIs, not a resale of anyone’s ChatGPT or Claude subscription.
Yes. Publish first, verify a domain you control, point the hostname to your workspace and connect HTTPS from your account. Add your own service API credentials as private app variables. Your app can then use the payment, email or other APIs you choose. Stripe and Resend can also power quote payments and reviewed customer emails directly in OSP after you enable them in Business setup. Retell API access can be verified; voice-agent enrollment and mailbox hosting are not included.
Every plan includes a monthly AI allowance for building and improving your business. Grow includes three times Launch’s allowance; Scale includes six times. Models and tasks use different amounts, so this is not unlimited usage or a fixed number of finished projects. Your account shows the remaining allowance and the maximum spend before each request. No automatic overage or surprise refills. See usage terms ↗︎
Cancel renewal in your account. Access continues through the paid period, then the live project goes offline and paid work stops. Pausing the workspace does not cancel the plan. Ask account help to coordinate migration or deletion; saved files are not silently erased. Review the plan details before buying.
No. The current iPhone app, browser tools and managed website service remain separate. Starting this workspace does not change an existing subscription.
