Replit Agent 3
Replit
Autonomous coding agent that builds, tests, and fixes apps automatically with long runtimes and workspace integrations.
Key features
- Autonomous App Construction: Builds full applications from project context and instructions, orchestrating multiple development steps (scaffolding, dependency installation, and initial code generation) without continuous human input.
- Automated Testing and Fixing: Runs test suites, detects failing tests or runtime errors, and iteratively applies fixes to source code until tests pass or a defined stopping condition is met.
- Extended Runtime Sessions: Supports long-lived agent runs (advertised up to 200 minutes) to handle multi-step workflows, long-running builds, or extensive debugging sessions that shorter agents cannot complete.
- Tool and Workspace Integrations: Connects with external collaboration tools such as Slack and Notion to post results, receive triggers, and integrate agent activity into team workflows and documentation.
- Sandboxed Code Execution: Leverages Replit's code-exec/eval infrastructure to execute generated Python (and other) code in ephemeral, unprivileged containers for numerical reasoning, testing, and validation.
- Multi-step Orchestration and State Handling: Manages sequential tasks, preserves context across steps, and can coordinate edits, tests, and deployments across a project repository.
- Notification and Reporting: Produces actionable reports and sends notifications to integrated tools or channels about build status, test results, and applied fixes.
