The Unified Developer Platform

• Code: A Git host with mirrored repositories for fast, local-feeling operations. Replaces GitHub, GitLab, Bitbucket.

• Issues: Instantaneous, offline-first planning and issue tracking that syncs automatically. Replaces Linear, Jira, Asana.

• Docs: Documentation versioned alongside code, accessible with a keystroke. Replaces Notion, Confluence, Google Docs.

• Chat: Context-aware team chat channels and threads attached to specific work items. Replaces Slack, Discord, Google Chat.

• CI: Continuous integration with warm runners and shared caches for instant pipelines. Replaces GitHub Actions, CircleCI, Jenkins.

• Packages: A content-addressed, globally cached registry for all shipped artifacts with signed provenance. Replaces npm, Docker, PyPI.

• AI Agents: First-class AI primitives that can read and write across all platform surfaces with full context and an audit trail.

Plain offers seven integrated surfaces—Code, Issues, Docs, Chat, CI, Packages, and AI Agents—all powered by a single source of truth. This eliminates the need to assemble and manage disparate tools, reducing context switching and improving developer efficiency. The platform prioritizes speed with <50ms local-first sync, reliability with a 99.9% uptime SLA, an AI-first approach, and a keyboard-native interface.

Pricing is per-user with tiered options including Free, Hobby, and Pro, offering increasing limits on repositories, documents, CI minutes, and agent tokens, along with varying levels of support and features like SSO and audit logs.
