Floot
Also known as: floot.com, Floot Infinity, Floot MCP server
Floot is an app builder that customers drive from their own AI assistant, Claude, ChatGPT, Codex or Cursor, through a remote MCP server, and some older accounts still chat with Floot's own agent in the editor. It builds React and TypeScript apps with serverless endpoints, managed Postgres, sign in, payments, email and scheduled jobs, hosts them on a floot.app address or a custom domain, and runs tests and publish checks. Plans run from a free tier to Power at $100 a month.
Floot is an app builder from Floot, Inc. of San Francisco, a Y Combinator company whose careers page describes a seed round and tens of thousands of builders. It now centers on a remote MCP server, so a customer builds by asking its own assistant, whether Claude, ChatGPT and Codex, Cursor or any MCP client, while the project, code, database and hosting live in Floot. The project view has no prompt box, and some older accounts still chat with Floot's own agent in the editor.
Through the server, the assistant creates projects, reads, writes and patches files, adds packages, provisions databases and other resources, runs SQL, typechecks, runs Jasmine tests in a simulated browser, reads logs, screenshots and navigates the live preview in the user's open Floot tab, and publishes.
The apps it builds have a React and TypeScript frontend, serverless TypeScript endpoints, managed Postgres, sign in with Google or Microsoft, file storage, email, push, realtime updates, background tasks, timers and recurring jobs, with Stripe, Shippo, Gmail, Calendar and Drive built in and any HTTPS API callable with keys the AI never sees. Web apps can also ship as iOS and Android builds to TestFlight and Google Play. Each assistant connection holds full access, edit without publishing, read only or a single project, nothing publishes without an error check, and checkpoints restore earlier code.
Free costs nothing and gives 100 building actions a day, 3,000 credits at signup and $3 of hosting credit. Pro is $25 a month with 1,000 actions a day, 5,000 AI credits and $10 of hosting, and Power is $100 a month with 5,000 actions a day, 15,000 credits, $25 of hosting and five times as many agents in parallel, with two months free on yearly billing. Apps run on AWS with the backend, Neon database and files in the US East region and no region choice, secrets are encrypted with AWS KMS, accounts sign in by emailed code or Google, GitHub or Microsoft with optional two factor codes, and projects have owners and collaborators but no single sign on.
It fits founders and small teams who already work in Claude or ChatGPT and want a hosted full stack app with payments, email and jobs without managing infrastructure. It fits less well for teams that need a Git workflow, since Floot does not sync with a repository and code leaves as a zip on paid plans, for buyers who need hosting outside the United States, or for companies that require single sign on, finer roles or a named security attestation.

Integrations
Remote MCP server used from Claude, ChatGPT and Codex, Cursor and any MCP client. Built apps use Stripe, Shippo, email send and receive, Google and Microsoft sign in, and users' Gmail, Calendar, Drive, Outlook and OneDrive without keys, call any HTTPS API with keys entered outside the chat, take inbound webhooks, and connect to other Floot apps. The directory also lists PayPal, Square, Shopify, Twilio, WhatsApp, Zapier, Make, Slack, Google Sheets, Notion and S3.
In practice
A founder asks Claude to build a booking app on Floot. The assistant creates the project, writes the pages and endpoints, provisions the database, adds Stripe checkout, writes tests and runs them, then publishes after Floot's error check passes.
A small team gives a second assistant a read only Floot connection to review an app's code and logs, while one developer keeps full access to change and publish it.
An agency builds a member portal that emails a digest every morning on a recurring job, pulls events from each member's Google Calendar, and ships the same app to TestFlight for an iPhone version.

| Integrations & Tool Calling | Full |
|---|---|
|
Built apps take payments through Stripe with checkout, subscriptions, coupons and refunds, ship through Shippo, send and receive email, sign users in with Google or Microsoft, and reach each user's own Gmail, Calendar, Drive, Outlook and OneDrive, with no keys to manage for those services. Any HTTPS API can be called, with keys entered through a one time link on Floot's site so the AI only ever sees the variable name, and published apps accept inbound webhooks. One Floot app can call another's exported functions once the user connects them, and a fixed outbound IP serves APIs that allowlist callers.

| Workflow Orchestration | Full |
|
The building assistant works through Floot's tools step by step, slow calls return a job ID it can poll or cancel, up to 50 calls run at once per account, and Power sells five times as many agents working in parallel. Apps built on Floot run background tasks on every plan, where one task can start many more, plus timers from one minute to seven days ahead and recurring schedules on paid plans, each capped at 15 minutes a run with no automatic retry. Floot's own editor agent works in Plan, Build and Discuss modes with parallel file operations and queued messages. Sourcefloot.com/docs/integrations/jobsread 2026-11-08 |
|
| Knowledge Grounding & RAG | Partial |
|
A new chat rereads the project through file reading and code search tools, Floot's own guides reach the assistant through a tool call, and the assistant can read other projects on the same account, so project context is gathered on each run. Each project carries a system prompt of up to 16,000 characters sent with every change, a design prompt, and notes and plans kept as files in a Docs tab. Apps that need search over their own content can use embeddings for semantic search. Sourcefloot.com/docs/getting-started/editor-and-previewread 2026-11-08 |

| Human Oversight & Guardrails | Full |
|
Each assistant connection carries a permission level, full access, edit without publishing, read only, or a single project, and no tool can spend the customer's money. Nothing publishes automatically and every publish runs an error check first, checkpoints restore or revert code with agent created ones filterable, single files roll back through version history, and databases on paid plans restore to any point in the last seven days with an undo. Preview links last seven days, private publishing serves beta testers, and per tool approval prompts come from the assistant's own client.

|
| Security, Identity & Governance | Partial |
|
Accounts sign in by emailed code, Google, GitHub or Microsoft, with optional authenticator codes and ten recovery codes, and projects have two roles, owner and collaborator, with no view only level, while each assistant connection gets its own permission scope. Data is encrypted in transit and at rest, stored secrets are also encrypted with AWS KMS and never reach the AI, app passwords use bcrypt, and published apps get security headers, a rate limiting firewall and pinned safe versions of vulnerable npm packages. There is no single sign on or SCIM, and Floot names no SOC 2, ISO 27001 or HIPAA attestation. Sourcefloot.com/docs/platform/security-and-dataread 2026-11-08 |
|
| Observability & Auditability | Partial |
|
The assistant reads logs through a tool: preview backend requests from the last hour, browser console and network activity, published backend logs for 90 days, push records and job state, and the project view itself has no log screen. Plan and usage tabs track building actions, AI credits and hosting, each project shows credits used, email has delivery logs and a sending health view, and schedules show a cost estimate. When an account reaches a limit, the message names which assistant and project used the actions. Sourcefloot.com/docs/faqs/troubleshooting-and-support-flowread 2026-11-08 |
|
| Memory & State Persistence | Partial |
|
The MCP server keeps no state between calls and issues no session IDs, and the conversation is not stored on the project, so continuity comes from the files, the project's system prompt and an activity record Floot keeps for the life of the project, while annotations last about a day. For apps people build, Floot's in app AI gives agents and chatbots conversation history and memory stored in the app's own database, with no stated lifetime or purge path. Sourcefloot.com/docs/platform/security-and-dataread 2026-11-08 |
|
| Deployment & Data Residency | Not documented |
|
Apps run on AWS, with the backend on Lambda behind CloudFront and the backend, the Neon Postgres database and files in the US East region, and customers cannot pick another region or a private deployment. Custom domains come on paid plans and wildcard domains on Power. Paid plans can download the code as a zip and run it on a Node server, but every Floot package import breaks the build until it is replaced, so the download is a way off the platform, and mobile builds go out through TestFlight and Google Play.

|
| Prebuilt Agents / Templates / Packs | Partial |
|
Floot has no template library. Public projects can be duplicated as starting points when both owners are on paid plans, and a community showcase lists apps such as Union Worker OS and FileFoxPro. Ready made parts come as built in services for payments, shipping, email, sign in and calendar and drive access, plus an Examples feature that stages app states for review and native plugins such as RevenueCat for purchases inside mobile apps.

| Triggers & Channel Coverage | Partial |
|
Building starts when a person asks their own assistant in Claude, ChatGPT, Codex, Cursor or another MCP client, or types an idea on the dashboard, which opens a connected assistant with the prompt filled in, and other products can embed Floot for their own users through dynamic client registration. No webhook, schedule or API hands work to the builder on its own. The apps it builds do run on cron schedules, timers, inbound webhooks, received email and realtime events, for as long as the owner's plan pays.

|
| Model Flexibility & Routing | Partial |
|
Building runs on whatever model the customer's own assistant uses, and Floot recommends Claude Fable or at least Opus, or ChatGPT Astra or at least Sol. Floot's own editor agent draws on Anthropic, OpenAI, Google, Fireworks, Baseten, Cerebras and fal, with Floot choosing among them. In the apps people build, code picks a text model per call, GLM 5 by default or GPT 6 Luna and Sol, picks among image models, and can bring its own OpenAI or Anthropic key.

| APIs / SDKs / MCP Extensibility | Full |
|
The MCP server is the product's interface: streamable HTTP with JSON answers, OAuth 2.1 with PKCE and dynamic client registration, a discovery manifest, and one tool set for every client. Its tools create and list projects, read, write, patch, rename and delete files, add packages and provision databases and storage, run SQL, typecheck and tests, call app functions, capture and drive the preview, generate images, publish and unpublish apps, and create checkpoints. Each call counts as a building action, six tools are free, and there is no REST API or SDK. Sourcefloot.com/docs/integrations/what-your-ai-can-doread 2026-11-08 |

| Testing, Debugging & Optimization | Full |
|
A run_tests tool executes Jasmine specs with React Testing Library in a Node VM with a simulated browser, with Floot services stubbed by spies and limits of two seconds a test, 15 seconds a file and 20 files a call, and the assistant writes the specs and fixes what fails. A typecheck tool checks the code before it ships, every publish passes an error check before going live, and the Examples feature stages app states so people can review each one.

| Browser / Computer-use | Full |
|
The assistant drives the live preview in the user's own open Floot tab, taking screenshots, navigating pages and running code in the browser to click through what it built, and that tab has to be in front because Floot runs no hosted test browser. Floot Infinity, a Chrome extension for Floot's editor agent, opens other websites, inspects their designs and sets up integrations by working in the browser on the builder's behalf.

Pricing
Free plan with 100 building actions a day, or Pro at $25 a month with 1,000 actions a day, 5,000 AI credits and $10 of hosting.
A monthly or yearly plan that sets a daily allowance of building actions, a monthly pool of AI credits and a monthly hosting credit, with usage add ons for email, fixed IPs and payments.
Included quota
Pro includes 1,000 building actions a day, 5,000 AI credits a month and $10 of hosting a month. Power includes 5,000 actions a day, 15,000 AI credits and $25 of hosting.
What is public
Free, Pro and Power prices with yearly rates, the actions, credits and hosting each includes, top up and boost prices, and the fees for payments, email and fixed IPs.
Billing mechanics
A plan billed monthly or yearly, a daily building action allowance used by each assistant tool call, a monthly AI credit pool for in app AI and images, and a monthly hosting credit with a daily cap the owner sets.
Cost watchouts
Code download, scheduled jobs and collaborators need a paid plan. Pro takes 1% of live payments, email bills per thousand messages, a fixed outbound IP costs $10 a month per project, and top up credits expire after 60 days.
Variable cost rationale
The plan price is flat, and building actions reset daily, so heavy building days hit a ceiling before they hit a bill. Costs that move with use are AI credits for in app AI and images, hosting above the plan's credit up to a daily limit the owner sets, email volume, fixed IPs and the 1% payments fee on Pro.
Additional watchouts
Pricing FAQ text predates the move to building actions, and enterprise terms are not published.
Overage / add-ons
Credit top ups start at $20 for 20,000 credits and expire after 60 days, an Action Boost adds 5,000 building actions for $5, and hosting above the plan's credit stops at a daily limit set from $5 up to $10 on Pro or $25 on Power.
Sales call required
No, self serve available
Free / trial
The free plan has no end date and gives 100 building actions a day, 3,000 credits at signup, $3 of hosting credit for a year and five projects.
Lowest paid plan
Pro at $25 a month
Commercial notes
Floot, Inc. is a San Francisco company backed by Y Combinator. Building runs through the customer's own assistant over MCP, so model costs for building sit with that assistant's subscription.
Key ambiguities
The pricing FAQ still describes credits spent on AI changes and a 25,000 credit plan, while the docs bill building through daily building actions, and the FAQ's cancellation grace period conflicts with the docs.
Cancellation / refund
Monthly or yearly plans with two months free on yearly. Older credit plans close once a customer leaves them, and published apps stay up while hosting credit lasts after cancellation.
Support SLA / resale
Pro and Power add priority support. Power adds wildcard domains and unlimited mobile app builds.
