Replit Agent

What it does

Writes code

YesAgent authors the code and sets up the surrounding infrastructure from a plain-language description.Agent writes code, sets up infrastructure, and tests the result.docs.replit.com/features/agent/overview ↗

Debugs and fixes

YesAgent runs its own tests, reports what it found and fixes the issues itself.Agent reports back with a summary of its tests and automatically fixes any issues that crop updocs.replit.com/features/agent/app-test… ↗

Writes tests

PartlyReplit says Agent tests the app it builds by driving a real browser; it never claims Agent authors test code or a test suite.App Testing lets Agent test the apps it builds using an actual browser. Agent navigates through your application like a real user would, clicking…docs.replit.com/features/agent/app-test… ↗

Reviews code

NoAgent scans your own project for vulnerabilities, and Replit tells you to add code review separately; no diff or pull-request review surface is published.A scan is not a complete security review. Use it alongside code review, tests, dependency review, and checks of the running app.docs.replit.com/features/security/agent… ↗

Whole-codebase work

YesMax Mode is positioned for larger codebases, and Agent's security scan reads the whole codebase; existing GitHub repositories import and continue with Agent.Max Mode uses more capable models for complex tasks, larger codebases, and harder problems.docs.replit.com/features/agent/agent-mo… ↗

Ships it

YesAgent goes past the diff: it takes the app to a running, publicly reachable deployment on Replit's cloud.Yes. Once Agent builds your app, you can publish it directly from Replit with one click, with built-in hosting, monitoring, and support for custom…replit.com/products/agent ↗

Done-for-you service

NoYou run the software; on Enterprise, named Replit people help your teams adopt and scale it rather than building your product.Dedicated Product Advocate and Field Engineer: Named Replit partners who help your teams adopt Replit, scale up, and unblock.docs.replit.com/billing/plans/replit-en… ↗

How much it does unattended

Runs autonomously

YesReplit frames Agent's self-testing loop as the thing that lets it work for long stretches with nobody watching.Extended Autonomy: Enables Agent to work for longer periods without requiring human interventiondocs.replit.com/features/agent/app-test… ↗

Multi-agent

YesEach background task gets its own Agent with the full project context, and tasks run concurrently.Each task also gets its own Agent and inherits your full project context, so you don't repeat yourself. Tasks are independent: you can start the next…docs.replit.com/learn/build-in-parallel ↗

Agent permissions

YesPlan Mode reads the project without touching files, background tasks need an explicit apply, and paid escalations ask first.In Plan Mode, Agent reads your project and provides guidance, but it won't make any changes to your files.docs.replit.com/learn/plan-vs-build-mode ↗

Which models it runs on

Claude

YesAnthropic is one of the three model providers Replit requires to stay enabled for Agent.At least one model from OpenAI, Anthropic, and Google must remain enabled. You can disable other providers.docs.replit.com/features/collaboration/… ↗

GPT

YesOpenAI is one of the three model providers Replit requires to stay enabled for Agent.At least one model from OpenAI, Anthropic, and Google must remain enabled. You can disable other providers.docs.replit.com/features/collaboration/… ↗

Open models

PartlyOpen-source model providers are a real but second-class category for Agent: they exist as a provider policy and are off unless an admin turns them on.Open-source model providers are disabled by default. To make one available, select Enable all or Enable selected, then select Update.docs.replit.com/features/collaboration/… ↗

Model choice

PartlyYou pick the model only in Power or Max Mode on Core and Pro; Free Mode is routed by Replit with no selectable list.Builders on Core and Pro can choose an available model in Power Mode or Max Mode.docs.replit.com/features/agent/model-se… ↗

Where you use it

In your editor

YesAgent runs as a tool inside Replit's own in-browser Project Editor alongside the file editor and preview.Contain exactly one Project Editor tool, such as the file editor, Preview, or Agentdocs.replit.com/features/editor/editor-… ↗

On the command line

NoReplit's terminal surface is the workspace Shell, described as a typical terminal for files, packages and scripts, not an interface to Agent.Shell lets you work on your projects, like a typical terminal, for managing files, installing packages, and running scripts.docs.replit.com/features/workspace-tool… ↗

In your pipeline

NoThe GitHub connector is scoped to repositories, users and organizations; Replit's own connector list gives merge requests and pipelines to GitLab, not to Agent.GitHub: Access repositories, users, and organizationsdocs.replit.com/features/integrations/o… ↗

In a browser

YesAgent is used in the browser on replit.com, with first-party desktop and mobile clients carrying the same experience.The Replit Desktop App is a redesigned, native app for Windows and Mac. It has the same experience you get on the web, so you can create apps, chat…docs.replit.com/features/platforms/desk… ↗

Whose machine it runs on

Self-hosted

NoThe strongest isolation Replit sells is a dedicated Google Cloud project it operates itself on Enterprise; no customer-infrastructure deployment is offered.Dedicated GCP project, single-tenant optionreplit.com/enterprise ↗

Not established: Open source

What it costs to run

How it meters

YesA plan subscription includes a monthly credit allowance, and paid Agent work is metered by effort at each checkpoint rather than per seat or per token.Free Mode supports no-cost everyday Agent work for Core and Pro subscribers within its allowance. Paid modes and confirmed paid work use effort-based…docs.replit.com/billing/ai-billing ↗

Free tier

YesThe Starter plan is free and self-serve with a daily Agent credit allowance; only Enterprise routes through sales.The Starter plan gives you everything you need to start building on Replit. Create apps and publish your first project — all at no cost.docs.replit.com/billing/plans/starter-p… ↗

API access

PartlyThe only documented Replit API is an Enterprise-only beta Admin API for usage, workspaces, members, projects and budgets; none of its scopes invoke Agent.The Admin API gives Enterprise account admins scope-based, programmatic access to account analytics and administration features.docs.replit.com/teams/admin-api ↗

MCP server

YesReplit hosts an MCP server whose tools let an external client create, inspect, update and publish Replit Apps, and Agent also consumes external MCP servers.Replit MCP uses the Model Context Protocol to let you create, find, inspect, update, and publish Replit Apps from AI tools you already use.docs.replit.com/platforms/mcp-server ↗

Bring your own key

NoYour own keys work for the API calls your app makes, but the model behind Agent itself cannot be replaced.The model that powers the Agent experience itself runs on Replit's infrastructure and can't be swapped.docs.replit.com/help/agent-and-ai ↗

Buying it for a team

A company can buy it

YesEnterprise can be bought self-serve from inside the product on any plan, or through sales with invoicing and usage commitments.You can upgrade to Enterprise directly inside Replit. Builders on any plan — Free, Core, or Pro — can move to Enterprise without leaving the product.docs.replit.com/billing/plans/replit-en… ↗

Seat model

PartlySeats are not priced individually but they are capped: Core up to 5 collaborators, Pro up to 15 builders plus 50 viewers, Enterprise unlimited with no per-seat cost.Up to 15 builders: Invite up to 15 builders with pooled credits and budget controls. No per-user fees—everyone works from the same plan.docs.replit.com/billing/plans/replit-pro ↗

Pooled budget

YesTeam members draw on one pooled credit balance from the admin's account, with usage tracked per Workspace; Enterprise adds per-user overrides.Collaborative Workspaces: Create collaborative Workspaces with pooled credits from the admin's account; organize apps and track usage per Workspace.docs.replit.com/billing/plans/replit-pro ↗

Admin controls

PartlyEnterprise account admins decide which model providers and models Agent may use, per account and per Workspace, and routing cannot override the policy.Enterprise model controls let account admins manage which Agent models builders can select. Set a policy for the account, then set different model…docs.replit.com/features/collaboration/… ↗

Audit log

PartlyAudit logging, including Agent activity events and SIEM streaming, exists only on Enterprise and only admins can read it.Audit logs are available exclusively for Enterprise customers. Account admins can enable them in Settings.docs.replit.com/teams/identity-and-acce… ↗

Single sign-on

PartlySAML SSO is Enterprise-only and self-serve to configure; Replit's Enterprise page also claims OIDC, which the docs do not cover.Only organizations with an Enterprise plan are able to use SAML SSO. You can purchase the Enterprise plan directly from the pricing page or contact…docs.replit.com/teams/identity-and-acce… ↗

What happens to your code

Opt out of training

PartlyThe no-training commitment sits in the Commercial Agreement, which governs Pro and Enterprise; Free and Core fall under the Terms of Service and Privacy Policy, which publish no opt-out.Replit will not use Customer Content to develop or improve Replit's products or services, train machine learning models, or create derivative works,…replit.com/commercial-agreement ↗

Data residency

PartlyHosting is primarily United States Google Cloud with an opt-in India region; choosing a workspace region is a Pro capability, and Free and Core are assigned one automatically.Only Pro customers can select a specific Workspace region.docs.replit.com/features/collaboration/… ↗

Getting out

PartlyCode leaves easily - projects are Git-backed and download as a zip (docs.replit.com/help/projects-and-files) - but purchased credit packs expire six months after purchase and the unused balance does not survive.Expiration: Credit packs expire six months after the purchase datedocs.replit.com/billing/managing-spend ↗

Certifications
