Show HN: LocalGPT – A local-first AI assistant in Rust with persistent memory

I built LocalGPT over 4 nights as a Rust reimagining of the OpenClaw assistant pattern (markdown-based persistent memory, autonomous heartbeat tasks, skills system).

It compiles to a single ~27MB binary — no Node.js, Docker, or Python required.

Key features:

- Persistent memory via markdown files (MEMORY, HEARTBEAT, SOUL markdown files) — compatible with OpenClaw's format - Full-text search (SQLite FTS5) + semantic search (local embeddings, no API key needed) - Autonomous heartbeat runner that checks tasks on a configurable interval - CLI + web interface + desktop GUI - Multi-provider: Anthropic, OpenAI, Ollama etc - Apache 2.0

Install: `cargo install localgpt`

I use it daily as a knowledge accumulator, research assistant, and autonomous task runner for my side projects. The memory compounds — every session makes the next one better.

GitHub: https://github.com/localgpt-app/localgpt Website: https://localgpt.app

Would love feedback on the architecture or feature ideas.

Show HN: Craftplan – Elixir-based micro-ERP for small-scale manufacturers

My wife was planning to open a micro-bakery and we started looking at software to manage recipes, inventory, orders, and production. Everything was either expensive, too generic, or both. The workflows for a small-batch manufacturer aren’t that complex, but the pricing acts like they are.

So I built Craftplan. All the features were tailored to what she actually needed, and I figured other small-scale manufacturers (soap makers, breweries, candle makers, etc.) probably need the same things. So I’m putting it out there for free.

  - Live demo: https://craftplan.fly.dev (test@test.com / Aa123123123123)
  - GitHub: https://github.com/puemos/craftplan
  - Docs: https://puemos.github.io/craftplan
  - Self-hosting guide: https://puemos.github.io/craftplan/docs/self-hosting/
What it does:

  - Product catalog with versioned recipes (BOMs) and automatic cost rollups across materials, labor, and overhead
  - Inventory tracking with lot traceability, expiry dates, allergen/nutrition flags, and demand forecasting
  - Order processing with calendar-based scheduling and allocation to production batches
  - Production planner with make sheets, material consumption from specific lots, and cost snapshots
  - Purchase orders with receiving workflow that auto-creates inventory lots
  - Basic CRM for customers and suppliers
  - CSV import/export, iCal calendar feed, JSON:API and GraphQL endpoints
Experience building with Elixir, Ash and Liveview:

  - Speed: you get to test and improve things sooo fast. The DSL makes it simple to translate your thinking into live product
  - Extensibility: With Ash + LiveView you can add more features so easily. Adding JSON:API + Grapghql was a few minutes.
  - UX: I believe LiveView makes it simple to deliver great UX since it forcing you to keep things simple with no so much interaction overhead which most of the time means better and simple experience
Self-hosting:

  - Docker image: `ghcr.io/puemos/craftplan` (amd64 + arm64)
  - Docker Compose bundles PostgreSQL 16 + MinIO.

Other details:

  - Email config from UI (SMTP, SendGrid, Mailgun, Postmark, Brevo, Amazon SES)
  - API keys encrypted at rest (AES-256-GCM)
  - Role-based access (admin/staff)
  - Tech stack: Elixir, Ash Framework, Phoenix LiveView, PostgreSQL
  - License: AGPLv3

Feedback welcome (and needed!)

Show HN: I saw this cool navigation reveal, so I made a simple HTML+CSS version

Two clip-paths, over the navigation:

- The first clip-path is a circle (top-left corner) - The second clip-path is a polygon, that acts like a ray (hardcoded, can be improved)

The original work by Iventions Events https://iventions.com/ uses JavaScript, but I found CSS-only approach more fun

Show HN: Look Ma, No Linux: Shell, App Installer, Vi, Cc on ESP32-S3 / BreezyBox

Example repo: https://github.com/valdanylchuk/breezydemo

The underlying ESP-IDF component: https://github.com/valdanylchuk/breezybox

It is something like Raspberry Pi, but without the overhead of a full server-grade OS.

It captures a lot of the old school DOS era coding experience. I created a custom fast text mode driver, plan to add VGA-like graphics next. ANSI text demos run smooth, as you can see in the demo video featured in the Readme.

App installs also work smoothly. The first time it installed 6 apps from my git repo with one command, felt like, "OMG, I got homebrew to run on a toaster!" And best of all, it can install from any repo, no approvals or waiting, you just publish a compatible ELF file in your release.
