Graphite, a Blender-inspired 2D procedural design Rust app▲785
For the past three years I've been building what I hope will be the next Blender, tackling the lack of any good 2D design or image editing tools outside the Adobe monopoly. This was our first year participating in Google Summer of Code and this Q3 update includes the big payoff from that, covering the most progress we've made so far as a project. If you're a Rust dev, consider getting involved as we apply for the next GSoC in the new year— you could be our intern next summer :) Q3 progress report: https://graphite.rs/blog/graphite-progress-report-q3-2024/

Railway▲405
Hacked together a service in Go https://github.com/xlab/cdn-s3-go that routes content request to any arbitrary S3-compatible bucket. Some infra providers are offering free egress, but buckets are only private (hello Railway), and not geo-distributed. An L4 balancer will cost a fortune (hello Cloudflare). cdn-s3-go solves this by looking up objects, generating a pre-signed URLs and redirecting the clients directly. Free egress, cheap public geo-distributed CDN!

Performant intracontinental public transport routing in Rust▲167
I made a public transport route planning program that's capable of planning journeys across Europe or North America! There's only one other FOSS project I know of (MOTIS/Transitous) that can do transit routing at this scale, and in the testing I've performed mine is about 50x faster. I've spent a few weeks on this project now and it's getting to the point where I can show it off, but the API responses need a lot of work before they're usable for any downstream application. Example query (Berlin to Barcelona):…

LocalGPT – A local-first AI assistant in Rust with persistent memory▲331
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:…

Horizon – GPU-accelerated infinite-canvas terminal in Rust▲84
Tabs, splits, and tmux work fine until you have several projects open with logs, tests, and long-running shells. I kept rebuilding context instead of resuming work. Horizon puts shells on an infinite canvas. You can arrange them into workspaces and reopen later with layout, scrollback, and history intact. Built in 3 days with Claude/Codex, dogfooding the workflow as I went. Feedback and contributions welcome.

Fleet – Experimental build tool for Rust that’s up to 5x faster▲63
Fleet is an experimental fast, lightweight, open-source, build tool for Rust. Builds with Fleet enabled are up-to 5x faster! For a production repository (infinyon/fluvio) which we tested, we were able to cut down our incremental build times from 29 seconds down to 9 seconds, boosted by Fleet. We saw even better results on dimensionhq/volt, with our build times cut down from 3 minutes to just 1 minute - a 3x speed improvement! How does fleet work? Fleet works by optimizing your builds using existing tooling available in the Rust ecosystem, including seamlessly integrating sccache,…

Keystone▲125
We kept hitting the same wall: you clone some arbitrary repo and just want it to run without any configuration work. So we built Keystone, an open source tool that spins up a Modal sandbox, runs Claude Code inside it, and produces a working .devcontainer/ config (Dockerfile, devcontainer.json, test runner) for any git repo. We build on the dev container standard, so the output works with VS Code and GitHub Codespaces out of the box. Main use cases: reproducible dev/CI environments, self-describing repos, and safely sandboxed coding agents. Our goal is to encourage all repos to…

Open-source Railway, Render alternative running on Kubernetes clusters▲50
Hello everyone, We have been developing Agnost (https://agnost.dev) for some time and it has reached a point that we can share with the larger community. What is it? Agnost is an open-source self-hosted Railway.app, Render.com, Vercel.com, Netlify.com, etc. alternative running on Kubernetes clusters. You connect your GitHub, GitLab, or Bitbucket repo and Agnost takes care of building the image and deploying your apps to your cluster whenever you push new code to your repo. How it works? Under the hood, Agnost integrates several open-source platforms. For the build and push pipeline…

Nucleus – A security-hardened, Nix-native container runtime▲40
Hi HN, I've been building Nucleus, a lightweight Linux container runtime focused on two workloads: ephemeral AI-agent sandboxes and declarative NixOS services. It's a single Rust binary, no daemon. It is not a Docker replacement and not a strict subset of Docker either. I dropped the entire image-and-distribution half (no Dockerfile, no layers, no registry, no pull/push, no persistent storage layer) in exchange for going deeper on isolation and reproducibility. The rootfs is either a directory copied into tmpfs (agent mode) or a Nix-built closure mounted read-only (production mode). If…
