Local-first memory runtime for Claude Code, Codex, ChatGPT, MCP workflows, and local agents.
Works locally for free. Squish Cloud is available for cross-device sync.
Squish gives agents stable orientation, durable memory, and searchable session history across runs. Use it locally with no cloud dependency, or connect Squish Cloud for sync across machines.
npm i -g squish-memory && squish install --allSquish provides AI agent memory that persists between sessions, across agents, and across machines. It is a free local-first MCP server with built-in embeddings, a knowledge graph, and hybrid retrieval. Squish Cloud is the paid managed tier for sync, dashboard, and team features.
Cloud pricing:
- Local Free: $0
- Cloud Solo: $9/mo
- Cloud Pro: $29/mo
- Founder Pass: $49-$99
| Concept | What It Is |
|---|---|
| Recall | Durable memory — decisions, preferences, constraints |
| Sessions | Evidence from past agent runs |
| Pinned | Stable facts that do not decay |
| Beliefs | Passive model of user/project |
| Strategies | Active operating rules |
| Decay | Stale weak traces fade automatically |
| Graph | Reinforced relationships from usage |
Every AI coding agent starts from zero when a new session begins. The architecture decision from last week, the config you spent an hour debugging, the preference you mentioned yesterday — gone.
Built-in memory files like CLAUDE.md and .cursorrules help, but they have hard limits. They cap out around 200 lines, require manual curation, and do not work across agents. You end up copy-pasting the same context into every tool.
Squish gives you persistent memory for coding agents that scales without limits. No manual maintenance. No token waste. No agent lock-in.
| Layer | What It Does | Command |
|---|---|---|
| Recall | Durable memory — decisions, preferences, constraints that persist across sessions | squish recall |
| Sessions | Searchable history — past agent runs you can inspect for evidence and context | squish sessions search |
| Remember | Write to long-term memory — store new facts, decisions, observations | squish remember |
| Method | Token Usage | Cost per Session | Cross-Agent | Auto-Capture |
|---|---|---|---|---|
| Paste full context | ~2,000 tokens | $0.06 - $0.12 | No | No |
| LLM-summarized context | ~500 tokens | $0.02 - $0.05 | No | No |
| CLAUDE.md / .cursorrules | ~200 lines max | Free | No | No |
| Squish (local) | ~50-200 tokens | $0.00 | Yes | Yes |
| Squish (Cloud) | ~50-200 tokens | $0.00 | Yes | Yes |
Squish retrieves only the relevant memories for the current task. The average context injection is 50-200 tokens — a fraction of what you would paste manually.
npm install -g squish-memory && squish install --allThis installs the Squish CLI, MCP server, and plugin hooks for all detected agents.
Start your coding agent as usual. Squish runs in the background, auto-capturing decisions, constraints, preferences, and context.
squish remember "We chose PostgreSQL for team mode" --type decision
squish recall "project decisions"After a few sessions, search your agent history:
squish sessions search "postgres migration"
squish sessions related --repo-path .Close your session and open a new one. Your agent picks up where you left off — all context is restored automatically.
squish context # See what your agent remembers
squish stats # Check memory healthWorks locally free. Paid Squish Cloud is available at squishplugin.dev for sync, dashboard, and team features.
Squish works with any AI coding agent that supports MCP (Model Context Protocol) or HTTP connections. One memory server, shared across all of them.

Add Squish to any MCP-compatible client:
{
"mcpServers": {
"squish": {
"command": "squish-mcp",
"args": ["--http", "--port", "8767"],
"env": {
"SQUISH_DB_PATH": "./squish-data"
}
}
}
}For cloud-connected agents:
{
"mcpServers": {
"squish-cloud": {
"type": "url",
"url": "https://api.squishplugin.dev/mcp",
"headers": {
"Authorization": "Bearer <your-token>"
}
}
}
}Most memory tools need a second LLM for embeddings and retrieval. That means extra API costs, latency, and infrastructure you have to manage.
Squish uses local embeddings by default. Zero LLM dependency. 1-5ms latency. $0 runtime cost in local mode.
Bring your own LLM if you want — Squish supports external embeddings and reasoning, but nothing requires it.

Squish uses a 4-stage pipeline to process memories:
- Capture — Filters noisy tool output, promotes what matters (decisions, constraints, preferences)
- Filter — Deduplicates, resolves contradictions, scores importance
- Store — Persists to SQLite/PostgreSQL with graph relationships and embeddings
- Retrieve — Hybrid search combines keyword, semantic, recency, and importance scoring

Squish is a local-first memory runtime for AI coding agents. It gives your agents stable orientation, durable memory, and searchable session history across runs. Think of it as a brain that persists between sessions — your agents remember decisions, constraints, preferences, and context without you having to re-explain everything. In v1.6.0, Squish also searches past agent sessions as evidence, so agents can inspect prior work instead of starting from zero.
No. Squish works locally by default with zero API keys. It uses local embeddings (TF-IDF) and SQLite storage. You can optionally configure an external LLM for enhanced reasoning, but it's not required. An API key is only needed if you want to use the paid Squish Cloud for cross-device sync.
Squish is the only option that works locally with zero external dependencies. mem0 requires Qdrant (a vector database) and cloud API calls. agentmemory requires iii-engine. Squish uses SQLite and local embeddings by default. See the full comparison in the Why Squish section above.
Yes. Squish works with any MCP-compatible agent. One memory server is shared across Claude Code, Cursor, Codex, Copilot, Gemini CLI, and any other agent that supports MCP. Memories are available to all connected agents.
Yes. In local mode, all data stays on your machine in an encrypted SQLite database. Nothing is sent to any cloud service. AES-256-GCM encryption protects sensitive memories. In cloud mode, data is encrypted in transit and at rest.
Squish supports SQLite (default, local) and PostgreSQL (team mode). SQLite requires zero configuration. PostgreSQL is used for team workspaces and shared memory across multiple users.
squish recall searches your long-term memory — distilled facts, decisions, and preferences that Squish has captured and organized. squish sessions search searches raw past agent runs — the actual messages, commands, and file changes from previous Claude Code, Codex, or OpenCode sessions. Recall gives you what the system decided to remember. Sessions give you the evidence.
