Eidentic

Initial release of Eidentic — agents that remember.

An open-source TypeScript SDK for building AI agents with self-improving memory and production fundamentals built in.

Install: npm install eidentic · Scaffold: npm create eidentic@latest

32 packages on npm under eidentic and @eidentic/*. Highlights:

• Self-improving 4-tier memory: self-editing blocks, lexical+vector recall, temporal knowledge graph, sleep-time consolidation — plus governance: state-transition timelines, corroboration tiers, consent manifests, portable export, identity merge
• Durable execution: checkpoint/resume, workflows with suspend/resume (human-in-the-loop), per-step retry, versioned runs
• Production server: auth, pre-auth rate limiting, quotas, multi-tenant isolation, HMAC-signed webhooks, graceful drain
• Sandboxed tools (files, bash, web, browser), MCP host+server with governance, A2A
• Enforced cost ceilings, model routing/fallback/caching, prompt versioning with canary
• Eval harness with CI baselines — and the first official LoCoMo results: memory mode beats the full-context baseline on temporal reasoning (+12.1pp) and adversarial robustness (+15.7pp) at 95.3% fewer tokens per query
• React hooks, Next.js handler, Studio dev UI, CLI
• Runs on Node, Bun, Deno, and the edge. Apache-2.0.
