# AtticDB

> Local, durable memory for coding agents. One Rust binary. It acks a write only after fdatasync.
> It wires into Claude Code, Copilot CLI, VS Code and Codex. MIT or Apache-2.0.
> Early: fine for a laptop, not for production yet.

To install and connect AtticDB for a user, follow https://atticdb.com/install.md.

## Install

- [Install steps for agents](https://atticdb.com/install.md): what to run, in order, to install AtticDB and connect the app you run in.
- [Install](https://docs.atticdb.com/install.md): Install AtticDB on macOS, Linux or Windows. atticdb setup connects your apps, and atticdb doctor checks the install.

## Docs

- [Overview](https://docs.atticdb.com/index.md): AtticDB is an agent memory database in Rust. It stores turn history and keyed facts. A write is acked only after it is synced to disk.
- [Install](https://docs.atticdb.com/install.md): Install AtticDB on macOS, Linux or Windows. atticdb setup connects your apps, and atticdb doctor checks the install.
- [Connect your apps](https://docs.atticdb.com/connect.md): How atticdb connect adds AtticDB to VS Code, Copilot CLI, Claude Code and Codex, and what each part writes.
- [MCP tools](https://docs.atticdb.com/mcp.md): atticdb mcp gives the model memory_append, memory_recent, memory_search and the fact tools. How it finds the home and the server.
- [Shell verbs and studio](https://docs.atticdb.com/cli.md): Run the same 6 memory tools from a shell. atticdb studio serves a read-only web page about your memory, on loopback.
- [Server and HTTP API](https://docs.atticdb.com/http-api.md): atticdb serve listens on loopback TCP and a Unix socket. Its HTTP routes, write errors and the outcome rule for retries.
- [How it works](https://docs.atticdb.com/how-it-works.md): 1 append-only tape is both WAL and store. Group commit, CRC32C frames, idempotent writes and the read-only floor.
- [Windows](https://docs.atticdb.com/windows.md): AtticDB on Windows x86_64: the profile rule, loopback TCP with a proof, weaker durability, and what each app gets.

## Optional

- [Benchmarks](https://atticdb.com/benchmarks): Durable acks per second and latency for AtticDB, Redis, Valkey, DiceDB and SQLite on NVMe and Premium SSD v2. 7 runs, raw data linked.
- [Compare](https://atticdb.com/compare): How AtticDB compares with Mem0, Zep, Letta, Supermemory, Redis Agent Memory, Cognee and Engram. Sourced facts, including where we lose.
- [Pricing](https://atticdb.com/pricing): AtticDB is free on your own disk, forever. Cloud sync, backups and team memory are planned. No per-memory or per-call fees.
- [Source on GitHub](https://github.com/Clawdlinux/atticdb): the code, releases and issues.
- [Our agent memory raced SQLite and Redis. It won on cloud disks and lost on reads.](https://atticdb.com/blog/we-raced-sqlite-and-redis): What "saved" really means, where our tiny agent memory beats SQLite and Redis, where it loses, and how to try it in a few minutes.
