Local-first memory and secrets for AI agents, portable across every harness

60/100MonitorFreeFree

Signet is a rare, genuinely portable memory layer for AI agents — switch harnesses without losing context, with inspectable, source-backed memory. The local-first design is a real plus, but setup demands CLI comfort. Skip it if you're happy with one tool's built-in memory and don't need cross-harness persistence.

Skip it if

Skip Signet if you're happy with one tool's built-in memory, don't need cross-harness persistence, or prefer a fully managed cloud service with zero setup overhead.

The 30-second take
Biggest gripe

Self-hosting means you handle daemon uptime and updates; expect occasional maintenance time to keep it running smoothly.

Price reality

Signet is free and open-source (Apache 2.0), so the cost is your time and infrastructure. Unlike subscription memory services (e.g., MemGPT's cloud plans), you pay zero dollars but own the ops burden.

About Signetai

FreeAdvancedAPI availableCLI · API · Web

Signet is a self-hosted, Apache 2.0 licensed memory and context layer for AI agents. It keeps memory and credentials outside any single harness, so you can inspect, carry, and switch between Claude Code, OpenCode, OpenClaw, Codex, Hermes Agent, Pi, or Oh My Pi without losing context. Designed for developers and power users running multiple coding agents, Signet installs as a single static binary that runs a local daemon, SQLite workspace, and web dashboard — no cloud account required. The core feature is automatic session distillation. When sessions end or go idle, the dreaming loop runs: it extracts entities, claims, and relationships into a knowledge graph, supersedes stale context with provenance, and keeps memory current without manual saves. Retrieval and ranking happen entirely on-device with no LLM at search time, and every memory links back to the source artifact that justifies it. The inspectable dashboard supports graph traversal, recall, and repair. Beyond memory, Signet manages secrets: credentials are stored encrypted and models can use them without seeing plaintext. It supports multi-agent scoping (isolated, shared, or group memory) and integrates via hooks, MCP, and runtime plugins. The latest update introduces a unified memory system that handles both curated knowledge and structured data from one place, and adds support for Hermes Agent and OpenClaw. Signet positions itself as a privacy-first alternative to cloud memory services like MemGPT or ChatGPT's memory. Early results on the MemoryBench harness average 97.6% LongMemEval answer accuracy, one of the only local-first systems with SOTA recall on a shared eval. It requires technical comfort with CLI setup and daemon management — not a zero-config tool.

Behind the Verdict

When you're juggling multiple coding agents — Claude Code for one project, Codex for another, OpenClaw for something else — memory that stays inside a single harness is a trap. Signet fixes that by keeping context and credentials outside any one tool. It's a genuine differentiator: switch harnesses, keep your memory, and your secrets stay encrypted. Pick this if you build multi-agent systems or run a swarm of tools. The dreaming loop automatically distills idle sessions into structured memory, extracting entities and claims with provenance. That's a massive time-saver for anyone tired of manually saving context. The graph-based retrieval with no LLM at search time is also fast and private — everything stays on-device. The flip side: this is not for the faint of heart. You need comfort with CLI setup, daemon management, and reading logs. There's no managed cloud offering, so you own the maintenance. If you prefer zero-config, fully managed memory, you'll want something like MemGPT or a built-in memory feature instead. Compared to those alternatives, Signet's main edge is portability and inspectability. Every memory carries a source — you can trace why the agent knows something. That's a level of transparency most cloud services don't offer, and it's valuable for debugging and trust. The 97.6% LongMemEval accuracy from MemoryBench is impressive, but remember it's under a strict rules profile — real-world results will vary. Watch out for the learning curve. The CLI wizard is simple enough — one command installs everything — but managing the daemon and understanding hooks/MCP takes time. Also, memory quality depends on your own embedding and model stack, so you'll want to configure that carefully. If you're okay with that, Signet is a powerful addition to your AI

Real-world workflow fit

Concrete scenarios for the personas Signetai actually fits — and what changes day-one when you adopt it.

Multi-agent developer

You run Claude Code and OpenClaw for different tasks and want shared context.

Outcome: Install Signet once, configure both harnesses, and memories saved in one are recallable in the other — no manual sync.

Privacy-conscious team

Your team needs agent memory that never leaves the corporate network.

Outcome: Self-host Signet on a local machine; all memory and embeddings stay on-device, with the dashboard for audit and repair.

Power user switching tools

You're switching from Codex to OpenCode for a project and fear losing context.

Outcome: Signet carries your memory — preferences, decisions, and entity relationships — so you pick up where you left off instantly.

Use Cases

Limitations

  • Signet is a local-first, self-hosted memory and context layer for AI agents, requiring self-management of infrastructure including a daemon and SQLite workspace.
  • It is installed via command-line (curl or npm) and configured primarily through CLI and MCP/hooks, making it suited to users comfortable with technical setup.
  • The tool relies on your own model and embedding stack for operations like dreaming and recall, so no built-in AI model is provided.

Hidden costs & gotchas

What the public pricing page doesn't put in bold. Captured from pricing-page footnotes, contract terms, and recurring complaints.

  • Self-hosting means you handle daemon uptime and updates; expect occasional maintenance time to keep it running smoothly.
  • Windows users need a package wrapper (npm) instead of the native binary — slightly less smooth than macOS/Linux.
  • Advanced features like remote connectors and managed deployments need extra configuration and possibly your own infrastructure.

Where the pricing makes sense

The company stage and team size where Signetai's pricing actually pencils out — and where peers do it cheaper.

Signet is free and open-source (Apache 2.0), so the cost is your time and infrastructure. Unlike subscription memory services (e.g., MemGPT's cloud plans), you pay zero dollars but own the ops burden.

Setup time & first value

How long it actually takes to get something useful out of Signetai — broken out by persona, not the marketing-page minute.

For a developer on macOS/Linux, install and setup take about 5 minutes: run the one-liner, `signet setup`, and you're ready to remember/recall. Windows via npm wrapper adds a couple minutes. Non-interactive or remote daemon setups take longer.

Switching to or from Signetai

How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.

Migrating in
  • From Claude Code's built-in memory: Signet's hooks and AGENTS.md sync can import your existing context files, then you rely on dreaming for ongoing distillation.
  • From MemGPT or cloud memory: export your memories and re-ingest as documents; recall with provenance will rebuild the knowledge graph.
Migrating out
  • To another memory system: since Signet stores memory as files (SQLite + sources), you can export the database and documents and port them manually.
