Show HN: It's a Plan – a self-hosted, open-source alternative to Linear

It's a Plan, a self-hosted, open-source project management tool built as an alternative to Linear, Plane, and Jira, integrates AI agents as team members with roles, permissions, and assignee slots. The tool, developed by croffasia, offers a REST API, MCP server, and signed webhooks, and is under active development with breaking changes expected before the first stable release.

Self-hosted, open-source project management and issue tracking, and an alternative to Linear, Plane, and Jira. The difference: AI agents work here like any teammate. Hand them issues, or run the whole thing over the REST API, webhooks, and MCP. If It's a Plan looks useful to you, star the repo ⭐ — it helps other people find it.

Here an agent is a real member of the team. It has a role, permissions, and an assignee slot, and it works the same board your people do. It's a self-hosted, open alternative to Linear, Plane, and Jira. You run it on your own server and database. Own your stack. Your server, your database. No per-seat fees, no lock-in. Agents as teammates. Give an agent a model, a prompt, skills, and tools. Assign it issues like you would a person. One board for both. People and agents share the same board, threads, and cards. Automate anything. Drive it all through the REST API, MCP, and signed webhooks. Heads-up: this is under active development. Expect breaking changes before the first stable release. Tracking - Configure issues per project: custom fields, labels, states, and issue types - Kanban, table, timeline, and calendar views, with configurable display fields and two-level grouping - Save any view as a reusable template - Configurable dashboards for project analytics: throughput, breakdown, pulse - Custom quick actions that run on an issue - Freeform notes boards: sticky notes on a canvas, with colors, checklists, and connections - Share a view or an issue by public link, read-only and without sign-in - Initiatives that group and track work across projects - Auto-archive, a notification inbox, role-based access control, and more AI agents - Agents as project members with their own permissions and assigned issues - Configure each agent's model, system prompt, tools, and reusable skills — built on the Mastra https://github.com/mastra-ai/mastra agent framework - Mention an agent in a comment to trigger a run - Scheduled agent runs - Built-in chat with per-agent conversation history Platform - REST API with an OpenAPI reference and API keys - MCP server, so an external assistant can read and change issues through the same API - Outgoing webhooks: subscribe to events, signed payloads, and retries with a delivery log - Email and password, passkey, and Google sign-in - Notifications by email SMTP or Resend and Telegram, with per-member preferences - Instance administration: storage limits, mail transport, and instance-wide settings Requirements: Docker and a domain behind a TLS-terminating reverse proxy. git clone https://github.com/croffasia/itsaplan.git cd itsaplan cp .env.example .env set API URL, APP URL, and the secrets docker compose up -d --build One command brings up the whole stack: Postgres, MinIO, api, worker, bot, and web. The first account registered becomes the instance admin.
