Moltis recently hit the front page of Hacker News. Please open an issue for any friction at all. I'm focused on making Moltis excellent.

Secure by design — Your keys never leave your machine. Every command runs in a sandboxed container, never on your host.

Your hardware — Runs on a Mac Mini, a Raspberry Pi, or any server you own. One Rust binary, no Node.js, no npm, no runtime.

Full-featured — Voice, memory, cross-session recall, automatic edit checkpoints, scheduling, Telegram, Discord, browser automation, MCP servers, SSH or node-backed remote exec, managed deploy keys with host pinning in the web UI, a live Settings → Tools inventory, Cursor-compatible project context, and context-file threat scanning — all built-in. No plugin marketplace to get supply-chain attacked through.

Auditable — The agent loop + provider model fits in ~5K lines. The core (excluding the optional web UI) is ~196K lines across 46 modular crates you can audit independently, with 3,100+ tests and zero unsafe code*.

Security

Zero unsafe code* — denied workspace-wide; only opt-in FFI behind local-embeddings flag
Sandboxed execution — Docker + Apple Container, per-session isolation
Secret handling — secrecy::Secret, zeroed on drop, redacted from tool output
Authentication — password + passkey (WebAuthn), rate-limited, per-IP throttle
SSRF protection — DNS-resolved, blocks loopback/private/link-local
Origin validation — rejects cross-origin WebSocket upgrades
Hook gating — BeforeToolCall hooks can inspect/block any tool invocation
Supply chain integrity — artifact attestations, Sigstore keyless signing, GPG signing (YubiKey), SHA-256/SHA-512 checksums

See Security Architecture for details. Verify releases with gh attestation verify <artifact> -R moltis-org/moltis or see Release Verification.

Features

AI Gateway — Multi-provider LLM support (OpenAI Codex, GitHub Copilot, Local), streaming responses, agent loop with sub-agent delegation, parallel tool execution
Communication — Web UI, Telegram, Microsoft Teams, Discord, API access, voice I/O (8 TTS + 7 STT providers), mobile PWA with push notifications
Memory & Recall — Per-agent memory workspaces, embeddings-powered long-term memory, hybrid vector + full-text search, session persistence with auto-compaction, cross-session recall, Cursor-compatible project context, context-file safety scanning
Safer Agent Editing — Automatic checkpoints before built-in skill and memory mutations, restore tooling, session branching
Extensibility — MCP servers (stdio + HTTP/SSE), skill system, 15 lifecycle hook events with circuit breaker, destructive command guard
Security — Encryption-at-rest vault (XChaCha20-Poly1305 + Argon2id), password + passkey + API key auth, sandbox isolation, SSRF/CSWSH protection
Operations — Cron scheduling, OpenTelemetry tracing, Prometheus metrics, cloud deploy (Fly.io, DigitalOcean), Tailscale integration, managed SSH deploy keys, host-pinned remote targets, live tool inventory in Settings, and CLI/web remote-exec doctor flows

How It Works

Moltis is a local-first persistent agent server — a single Rust binary that sits between you and multiple LLM providers, keeps durable session state, and can meet you across channels without handing your data to a cloud relay.

Getting Started

Build & Run

Requires just (command runner) and Node.js (for Tailwind CSS).

git clone https://github.com/moltis-org/moltis.git
cd moltis
just build-css                  # Build Tailwind CSS for the web UI
just build-release              # Build in release mode
cargo run --release --bin moltis

For a full release build including WASM sandbox tools:

just build-release-with-wasm    # Builds WASM artifacts + release binary
cargo run --release --bin moltis

Open https://moltis.localhost:3000. On first run, a setup code is printed to the terminal — enter it in the web UI to set your password or register a passkey.

Optional flags: --config-dir /path/to/config --data-dir /path/to/data

Docker

# Docker / OrbStack
docker run -d \
  --name moltis \
  -p 13131:13131 \
  -p 13132:13132 \
  -p 1455:1455 \
  -v moltis-config:/home/moltis/.config/moltis \
  -v moltis-data:/home/moltis/.moltis \
  -v /var/run/docker.sock:/var/run/docker.sock \
  ghcr.io/moltis-org/moltis:latest

Open https://localhost:13131 and complete the setup. For unattended Docker deployments, set MOLTIS_PASSWORD, MOLTIS_PROVIDER, and MOLTIS_API_KEY before first boot to skip the setup wizard. See Docker docs for Podman, OrbStack, TLS trust, and persistence details.

Cloud Deployment

Provider	Deploy
DigitalOcean

Fly.io (CLI):

fly launch --image ghcr.io/moltis-org/moltis:latest
fly secrets set MOLTIS_PASSWORD="your-password"

All cloud configs use --no-tls because the provider handles TLS termination. See Cloud Deploy docs for details.
