OpenHuman alternatives (2026)

OpenHuman: GPL-3 local-first agent OS with real memory UX. Worth a look for personal orchestration; assume beta edges and price the subscription defaults honestly.

Its Catch: Vs Pi, Claude Code, OpenClaw, and OKF/ai-memory: OpenHuman is the TinyHumans desktop orchestrator + memory product, not a coding-agent CLI harness, Anthropic's CLI, a messaging agent, or a zero-LLM git memory wiki.

Below: 8 free or free-tier tools from the same category (agent memory tools), free and open source first, then the closest match by shared tags. Each keeps its own Catch.

  1. 1.EngramMIT persistent agent memory — MCP, CLI, TUI, SQLite

    Free / OSS · OSS/MIT · 7.4k GitHub stars

    VerdictMIT agent memory primitive. MCP/CLI/TUI on SQLite; not a full agent framework.

    CatchVs Mem0 / Letta / full agent frameworks: Engram is the memory primitive (store + retrieve + surfaces), not an orchestration framework or coding agent. “local or cloud” branding means optional hosted/sync gravity — day-one stays OSS you run. You still decide what gets written and when.

  2. 2.oh-my-hermesMIT Hermes-agent niche tooling — memory & workflows

    Free / OSS · OSS/MIT · 3.4k GitHub stars

    VerdictMIT Hermes-agent tooling. Niche, not a multi-host skill pack.

    CatchHermes-specific — not a generic Claude Code / Codex skill pack. Young surface; expect Hermes Agent as the host and follow upstream Hermes breaking changes. Vs ECC (multi-host ecosystem) and security-audit-skill (Cloudflare audit skill): oh-my-hermes is niche Hermes tooling, not a cross-harness coordination layer or a security scanner.

  3. 3.nanobotUltra-light self-hosted personal AI agent with WebUI, MCP, and memory

    Free / OSS · OSS/MIT · 49.2k GitHub stars

    VerdictMIT personal agent runtime. Self-host when you want MCP + memory + chat bridges in a small Python core.

    CatchYou operate the host, keys, and chat-app credentials; “ultra-light” still means a long-running service. Young surface with a large issue backlog — pin versions for production. Vs OpenHands / LibreChat (heavier coding or multi-model chat stacks) and OpenBot (governed coworker computers): nanobot is the small personal gateway, not a full browser-cowork platform or a repo-coding agent.

  4. 4.FridaySelf-hosted cognitive memory MCP for coding agents

    Free / OSS · OSS/MIT · 68 GitHub stars

    VerdictMIT self-hosted memory MCP. Use when coding agents need durable local memory without Mem0 Cloud.

    CatchVs Mem0 / Letta / Graphiti: Friday is the self-hosted MCP memory appliance for coding agents, not a multi-tenant memory API or a full agent OS. You operate Neo4j/Compose and embedding/model keys; star count is still early — pin and verify before production trust.

  5. 5.AX CheckHosted free agent-experience checklist + recorded coding-agent sessions

    Free / OSS · OSS/MIT

    VerdictFree hosted AX smoke test. Grades how agents use your product, not how good your model is.

    CatchGrades are provisional and technical-only — treat the report as a useful first pass, not a product-wide quality certificate. Vs Promptfoo / DeepEval: AX Check grades product AX (docs, CLI, MCP, SDK), not model quality, eval scores, or safety behavior. Hosted free is convenient; verify the session evidence and rerun after interface changes.

  6. 6.SupermemoryMIT memory/context engine with a local API

    Free / OSS · OSS/MIT · 31.3k GitHub stars

    VerdictMIT memory/context engine. Fast local/API path; verify the paid self-host boundary before planning a hosted deployment.

    CatchVs Mem0 / Letta / Graphiti: Supermemory leans into a local/API speed angle, not the same graph-orchestration shape. pricing caveat: the pricing page gates self-hosted deployments to paid tiers while the README documents a free local binary — read “self-host” as the OSS/local path, not a promise that every production deployment tier is free. You still own data policy and retrieval quality.

  7. 7.OpenVikingAGPL self-evolving context database for memory, RAG, and skills

    Free / OSS · AGPL-3.0 · 40.3k GitHub stars

    VerdictAGPL-3.0 self-evolving context DB. Broad memory/RAG/skills surface; network copyleft is a deployment decision, not a footnote.

    CatchAGPL-3.0 is strong copyleft, including the network-copyleft boundary when you modify OpenViking and offer it as a service. Get legal review before exposing a modified deployment over a network. Vs Mem0, Graphiti, and Letta: OpenViking is the context database spanning memory/RAG/skills, not simply a memory API, graph memory layer, or agent runtime.

  8. 8.OKF Agent MemoryGit-native dual-memory for agents — OKF v0.2 + embedded MCP

    Free / OSS · OSS/MIT · 824 GitHub stars

    VerdictMIT git-native agent memory. Use when you want OKF bundles and MCP retrieval without another database.

    CatchVs Engram / Mem0 / Supermemory / Letta: OKF is the git-native OKF+AAG dual-memory recipe with MCP, not a hosted memory SaaS or paging OS. You still author the Domain Codex and decide write discipline; empty knowledge/ stays empty.
