What it is
Replit started as an online coding environment and is now mostly an AI app builder. You describe what you want and Replit Agent plans the work, writes the code, sets up a database and publishes the app, all inside Replit's cloud. You can also open the code and edit it yourself.
The free Starter plan gives daily Agent credits, the lighter Lite build mode and one published app that goes offline after 30 days. Core is $20 a month ($18 billed yearly) with $20 of monthly credit and up to 5 collaborators; Pro is $100 a month ($90 yearly) with $100 of credit, up to 15 builders, 10 parallel agents and credits that roll over for two months. Free Mode lets Core and Pro users keep building within an allowance that refreshes every five hours; Power and Max modes draw on credits.
Our review
Replit's advantage is that the build and the running service live in the same account. The Agent writes the app, and Replit supplies the Postgres database, file storage, secrets, hosting and custom domains, with database rollback of up to 28 days on Pro. Bolt and v0 produce code faster for a prototype; Replit is stronger once real users depend on the result.
The billing has two layers, and the second is the one to watch. Agent work in Power or Max mode, hosting, outbound data and databases all draw from one monthly credit balance, $20 on Core and $100 on Pro, then move to pay-as-you-go. Free Mode helps: Core and Pro get an allowance that refreshes every five hours and uses Replit's own model routing. Routines, its scheduled agent jobs, cannot run in Free Mode and need a per-run budget.
Hosting got noticeably cheaper on 1 August 2026. Autoscale compute fell from $3.20 to $0.60 per million compute units, requests from $1.20 to $0.40 per million, outbound data from $0.10 to $0.05 per GiB, and database storage from $1.50 to $0.35 per GiB a month. A small internal tool now costs little more than the $1 monthly base fee.
Security is better documented than the vibe-coding label suggests. Replit holds SOC 2 Type II, is working towards ISO 27001, gives every customer an isolated Google Cloud project and scans apps with Semgrep and an LLM before publishing. Its terms still reserve the right to access private apps for troubleshooting and improving the service, and SSO, SCIM and single-tenant options sit on Enterprise only, which matters more to an IT team than any Agent feature.
Where it earns its place

Ship a working app with logins and a database to ten pilot customers
Build on Core at $20 a month in Free Mode, switching to Power Mode for harder fixes. Hosting a low-traffic Autoscale app costs about the $1 base fee plus small usage from the included credit.

Connect the data source, let the Agent build the dashboard and publish it privately. IT will want Enterprise for SSO and SCIM before it touches company data.

Pro at $100 a month shares credits across 15 builders and runs up to 10 Agent tasks in parallel, each reviewed before it merges; unused credit rolls over for two months.
Before you commit
- Setup
- Sign up in the browser and describe the app; a first working version usually comes from one prompt, with Plan Mode on Core and above for scoping first.
- Integrations
- Built-in Postgres, app storage, secrets and auth; MCP servers for external tools; Replit AI Integrations for model access without your own API keys.
- Data and privacy
- SOC 2 Type II and GDPR, ISO 27001 in progress; each customer gets an isolated Google Cloud project; SSO, SCIM, audit logs and single-tenant options are Enterprise only.
- Cost at scale
- Autoscale hosting is $0.60 per million compute units and $0.40 per million requests, and database compute is $0.16 an hour, all deducted from plan credits first.
- Limits
- Starter is limited to Lite build and one app for 30 days; Free Mode refreshes every five hours; Routines need Power or Max credits.
