Proliferate

Proliferate is an open source background agent platform that lets AI agents and engineers work from the same tools and environments. It creates isolated cloud sandboxes that mirror your production infrastructure, enabling agents to investigate issues, open pull requests, and run automations without manual intervention. Teams across product, design, engineering, and marketing can trigger agents from their existing tools and review results when they're ready.

• Mirrored Cloud Sandboxes: Agents work in 1:1 clones of your infrastructure (API, DB, Redis, Secrets) so results are production-accurate.
• Proactive Triggers: Agents respond automatically to events from Sentry, Linear, GitHub, Slack, and more — no manual kick-off required.
• Verification Steps: Every agent run produces a session report with diffs, audit trails, test results, and screenshots so you can trust what was done.
• End-to-End Workflow Automation: From error detection to committed PR, agents handle the full cycle including writing code, running tests, and checking previews.
• Org-Wide Context: Agents pull context from your codebase, internal docs, tickets, and tools to understand how your team works.
• Harnesses for Non-Engineers: PMs, designers, and marketers can trigger automations and ship changes without writing code or touching git.
• Broad Integration Support: Connects with GitHub, Sentry, Slack, Linear, Jira, Notion, Claude Code, and Cursor out of the box.
• Open Source & Self-Hostable: Fully open source with no limits when self-hosted; deploy on your own infrastructure with no credit card required.
• Credit-Based Usage: Each cloud plan includes monthly credits for agent actions; top up anytime from the dashboard without changing plans.
• Getting Started: Visit the GitHub repo to self-host for free, or join the waitlist for the hosted Starter or Team plans and book a demo to see it in action.
