TL;DR
Replit is built around its own Agent: you describe the app, the Agent builds it in Replit's workspace, and you publish it from there. If your own agent writes the code in your repository, floo is the alternative: a push to GitHub deploys the app with sign-in, data, schedules, previews, and agent keys from one config file.
- Who writes the code: on Replit, Replit Agent, including when you drive it through Replit's MCP server. On floo, whichever agent you already use.
- How it ships: Replit publishes a snapshot of the workspace. floo deploys every push to GitHub, and can deploy each pull request to its own preview URL.
- Agent access: Replit offers project-wide bearer tokens. floo gives each agent its own key, scoped to declared routes, with its identity passed to the app.
- Where Replit leads: no local setup at all, a browser workspace, checkpoints you can roll back to in one click, and publishing on every plan.

Who is each one for?
Replit's homepage pitches turning ideas into apps with no coding needed. Its Agent is the builder, and the workspace, database, auth, storage, and publishing all sit around it. If you are starting from a prompt and want everything in one browser tab, that is a good fit.
floo assumes the builder is already chosen. You work with Claude Code, Codex, Cursor, or another agent on your own machine, in a git repository. floo's job starts when the app needs to leave localhost: a URL, sign-in, data, schedules, and a way for agents to keep operating it. See where to host an app built with Claude Code.
How do they compare?
| Replit | floo | |
|---|---|---|
| Who writes the code | Replit Agent in the Replit workspace; SSH lets a local editor connect on paid plans | Your agent, in your repository |
| How it deploys | Publish a snapshot from the workspace | Each push to GitHub deploys to dev; a GitHub release deploys to prod |
| Kinds of workload | Autoscale, Static, Reserved VM, and Scheduled deployments | Web services, workers, and cron jobs in one app |
| Database | Managed Postgres with separate development and production databases | Managed Postgres with separate dev and prod databases, and a database branch per preview |
| Files | App Storage, private buckets on Google Cloud Storage | S3-compatible storage declared in config |
| Private access | Access controls (workspace-only, invite-only, or password), listed for Pro and Enterprise in Replit's deployment docs; visitors sign in through Replit | access_mode = "accounts"; invited people sign in with a floo account, including Google |
| Agent credential for the app | Project-wide external access token, one environment, expiring | Key per named consumer, scoped to declared routes, rate-limited, with request history |
| Previews | Development URLs, live while you work in the app | Pull request previews with their own URL and managed resources, off until you turn them on |
| Control surface | Workspace, plus an MCP server that drives Replit Agent | CLI with JSON output, and an HTTP API with an OpenAPI spec |
Can I bring code my own agent wrote?
Yes, but it moves into Replit. The GitHub import supports public and private repositories, and Replit honors AGENTS.md and CLAUDE.md files in the repository. Connecting a repository puts a development copy into a Replit sandbox, and you can push changes back to GitHub. Secret and environment variable values are not imported, and the docs we read do not describe deploying on a push to GitHub. Publishing saves a snapshot of the Replit App to the cloud.
On floo, the repository stays the source of truth. Your agent edits floo.app.toml and code, pushes, and floo deploys. floo deploys status --json tells it what happened, and floo logs query --json shows why something failed. See agent setup.
Does Replit's MCP server change that?
Replit's MCP server lets Claude, ChatGPT, Slack, or any MCP client create, update, and publish Replit Apps. Its update tool starts a Replit Agent run on the existing app. So your agent is directing Replit's agent, not shipping its own commits. That is useful if you like Replit Agent's output, and a second agent in the loop if you do not.
How does an agent get access to a private app?
Replit has a real answer here: external access tokens. They are bearer tokens you mint for one project, bound to either development or production, each with an expiry, meant for API traffic from CI, webhooks, bots, and scripts. Replit's docs note that anyone who has a token can reach the project, and the app does not learn which caller it is.
On floo, you declare the routes that accept machine access, then give each agent its own key:
floo apps consumers create report-agent
floo apps keys create report-agent --consumer report-agent --scope reports.access --rate-limit-rpm 60
The key works only on routes with that scope. floo strips it before the request reaches your code and passes the consumer's identity in headers, and every request is listed by key ID. The people's sign-in is separate: invited users never share a key with the agent. See how to give your agent its own API key.
Where is Replit stronger?
- No setup. A browser workspace and an Agent that builds from a prompt, with nothing to install.
- Checkpoints. Each checkpoint is a full snapshot of the app, and rolling back is one click. By default a rollback leaves the database alone.
- Production data guardrail. Replit Agent cannot touch the production database, and schema changes carry over when you publish.
- Publishing on every plan. Replit says any plan can publish an app.
Which should you choose?
Choose Replit when you want its Agent to build the app and you are content for the code and deploys to live in Replit. Choose floo when your own agent writes the software and you want it to stay a normal repository: each push deploys to dev, a GitHub release ships to prod, each pull request can get a production-shaped preview, invited people sign in, and every agent that operates the app has its own key.

Frequently asked questions
Can I host an app built with Claude Code on Replit?
You can import its GitHub repository into Replit, then publish from the Replit workspace. Replit's docs describe publishing from inside Replit; they do not describe deploying on a push to GitHub. Secret and environment variable values are not imported.
Does Replit's MCP server let my agent deploy its own code?
Replit's MCP server creates, updates, and publishes Replit Apps from Claude, ChatGPT, and other MCP clients. Updates start a Replit Agent run, so Replit's agent writes the change. floo deploys the commits your own agent pushes.
Can an agent call a private Replit app?
Yes, with an external access token: a bearer token for one project, bound to one environment, with an expiry. Replit's docs say anyone holding it can reach the project, and the app is not told who the caller is. On floo, each agent gets its own route-scoped key, and the app receives the consumer's identity.
When should I stay on Replit?
When you want Replit's Agent to build the app in the browser, without a local setup, and you are happy to keep the code and deploys in Replit.
