The whole project, in one pane of glass
Every session, decision, and human-in-the-loop request — coordinated live. This is the real dashboard, not a mockup.
Persistent memory, task coordination, and a human-in-the-loop queue for every Claude / Cursor / Windsurf session. Open source. Local-first. MCP-native.
Free tier: 1 project · 30 days · no credit card required · self-host for free, forever
Every session, decision, and human-in-the-loop request — coordinated live. This is the real dashboard, not a mockup.
Your AI tools don't talk to each other. Meridian is the layer that fixes it.
Every Claude tab boots blind. Run two in parallel and they duplicate work, contradict each other, and step on the same files.
Hit the token limit mid-task and the whole working state evaporates. Re-explaining what you've already shipped is a tax on every session.
Starting a fresh session means digging through git history, scrolling chat logs, and praying you remembered the latest decisions.
All seven features ship today. Open source, MSL-1.0.
North star, version goal, session focus — every tab reads the same. One save, everyone aligns.
claim_task locks work atomically. No two sessions pick up the same task twice.
When your AI gets stuck, it pauses and asks you — not us.
Sessions surface coordination questions to a single dashboard panel. Autonomous until it needs you — then back to work.
Editable constitution alongside the append-only log. The "current truth" cold sessions need before doing anything.
L0/L1/L2 compression. generate_handoff writes a file a fresh session can paste and resume in seconds.
Claude Code, Codex CLI, Claude Desktop, Cursor, Windsurf, LangGraph webhook — any MCP client, any OS.
Connect your repo once in Settings. Planning sessions get read_file, search_code, git_log and more — no Copilot, no extra connector, no local install.
Wire Claude Code and Codex to Meridian in 30 seconds. SessionStart injects your project context automatically. Stop fires a delta checkpoint before the session closes. Zero manual calls.

Injects your project state (goal, sprint, recent tasks, pinned decisions) into every new Claude Code / Codex session automatically.
Before the session closes: buckets completed tasks into an auto-capture note and writes a delta handoff so the next session can resume in seconds.

CLAUDE.md is static context — good for standing instructions, bad for tracking state. Meridian is live: sessions read and write to a shared DB in real time, coordinate sprint items atomically, queue HITL requests, and generate handoffs across context resets.
start_session, log_task, generate_handoff, etc.) and any compatible AI client can call them as built-in capabilities.
