Show HN: Moltis – AI assistant with memory, tools, and self-extending skills

Hey HN. I'm Fabien, principal engineer, 25 years shipping production systems (Ruby, Swift, now Rust). I built Moltis because I wanted an AI assistant I could run myself, trust end to end, and make extensible in the Rust way using traits and the type system. It shares some ideas with OpenClaw (same memory approach, Pi-inspired self-extension) but is Rust-native from the ground up. The agent can create its own skills at runtime.

Moltis is one Rust binary, 150k lines, ~60MB, web UI included. No Node, no Python, no runtime deps. Multi-provider LLM routing (OpenAI, local GGUF/MLX, Hugging Face), sandboxed execution (Docker/Podman/Apple Containers), hybrid vector + full-text memory, MCP tool servers with auto-restart, and multi-channel (web, Telegram, API) with shared context. MIT licensed. No telemetry phoning home, but full observability built in (OpenTelemetry, Prometheus).

I've included 1-click deploys on DigitalOcean and Fly.io, but since a Docker image is provided you can easily run it on your own servers as well. I've written before about owning your content (https://pen.so/2020/11/07/own-your-content/) and owning your email (https://pen.so/2020/12/10/own-your-email/). Same logic here: if something touches your files, credentials, and daily workflow, you should be able to inspect it, audit it, and fork it if the project changes direction.

It's alpha. I use it daily and I'm shipping because it's useful, not because it's done.

Longer architecture deep-dive: https://pen.so/2026/02/12/moltis-a-personal-ai-assistant-bui...

Happy to discuss the Rust architecture, security model, or local LLM setup. Would love feedback.

A naive question - pi is using jiti to hotreload extensions, but how does hotreloading work at all with Rust?

I haven’t yet tried openclaw but can someone tell me how is this project different than that? Is this basically a different take on the same thing as openclaw? Dont get me wrong im not against it I just was wondering if theyre basically doing the same thing? If that’s the case I actually appreciate both projects, but idk what theyre doing and how theyre different?

Cool!
One pain point I have with openclaw is compaction. It uses so many tokens that compaction happens often - but I'd say it's not great at keeping the thread. I think this could be a nice little benefit you offer folks if you can get higher quality continuity.

Very cool! I love the approach, OpenClaw is really cool but there's two major things holding me back for deploying it from friends a family;
- Cybersecurity (you can't expect a non-technical person to read a skill)
- Token usage (without a flat fee subscription it'll become expensive very fast)
I understand that security is a hard problem to solve but having a single binary + containers should definitely help! I'll definitely keep an eye on this.

Isn't the point of OpenClaw that the agent can modify itself?

Hello! I tried to run with podman but it get stuck in the login of my bot :( Would check it out later on the development.

Why can I only see gpt-5.2 and opus-4.5? Is this a limit on Moltis or can my API keys not access the latest models?

Very nice.
Though, I am looking forward to the next generation of AI agents that aren't named after a lobster
