Zikra — Team Memory for AI Agents
Not just session memory. A shared, governed memory layer for every agent, every person, and every project your team runs.
Website: zikra.dev · Self-hosted · MIT · Scales to millions of memories
Architecture: Governed project memory for teams of agents
Promotion kit: submission copy, launch posts, and directory targets

Most AI memory tools solve one problem: one agent remembers one session better.
Zikra solves a harder problem: multiple people running multiple AI agents across multiple projects — all sharing the same memory pool, with the right person scoped to the right project, the right agent pulling the right context, and millions of memories staying fresh through built-in hygiene scoring.
It's not session memory. It's the shared brain for an AI-native team.
| What you get | What that means |
|---|---|
| Multi-agent | Claude Code, Gemini CLI, Codex — one pool, one token |
| Multi-person | Owner / admin / dev / viewer roles per project |
| Multi-project | Isolated namespaces; one team runs veltisai, design, global |
| Scale | PostgreSQL backend — handles millions of memories without index rebuilds |
| Memory hygiene | Built-in hygiene prompt: confidence decay, orphan detection, stale cleanup |
| Structure | Not just "save text" — decisions, requirements, prompts, errors, session diaries |
| Auto-save | Stop + PreCompact hooks write every session automatically |

Getting Started
Step 1 — Install the server
git clone https://github.com/getzikra/zikra
cd zikra
python3 -m venv .venv
source .venv/bin/activate # Windows: .venv\Scripts\activate
pip install -e .
python3 installer.py # interactive setup, ~2 minutes
python3 -m zikra
The installer creates a .env file and generates your admin token. The server binds to http://localhost:8000 by default.
To reach it from other machines, run
cloudflared tunnel --url http://localhost:8000(free, gives you a permanent public URL likehttps://zikra.yourteam.com).
Step 2 — Enable MCP in Claude Code
Open Claude Code → Settings → MCP → Add Server and paste:
{
"mcpServers": {
"zikra": {
"url": "http://your-server:8000/mcp",
"headers": { "Authorization": "Bearer YOUR_ZIKRA_TOKEN" }
}
}
}
The installer does this automatically when run locally.
Step 3 — Connect your AI coding agent
Paste the prompt for your agent into a session. It handles both first install and updates.
Claude Code:
Fetch https://raw.githubusercontent.com/GetZikra/zikra/main/prompts/zikra-claude-code-setup.md
and follow every instruction in it.
This installs the Stop hook (auto-saves every session), PreCompact hook, and the live statusline bar showing run counts and memory stats.
Updating Zikra
Server:
cd ~/zikra && ./update.sh
Claude Code hooks — re-run the onboarding prompt. It detects your existing install and only refreshes what changed.

How results are ranked
Every search result passes through scoring:
- Age — recent memories rank higher. Half-life: 30 days. Floor: 0.05.
- Access frequency — frequently used prompts surface higher (log scale).
- Confidence — memories saved with lower
confidence_scorerank lower.
