Manta – A tool for FPGA Debugging and Rapid Prototyping
Hi HN! I'm Fischer, and I'm super stoked to share a project that I've been working on for a little over a year: Manta, an open-source, cross-platform, vendor-independent tool for debugging and rapid prototyping with FPGAs. This was originally my Master's Thesis at MIT, where I developed it for our course on FPGA design. We needed an alternative to vendor debugging tools, which only supported x86 machines running Windows or Linux. We were able to patch in macOS support with VMs, but as more students came bringing ARM-based devices, we needed a new tool. So I developed this. It's called Manta,…
Manta – A tool for FPGA Debugging and Rapid Prototyping launched on March 8, 2024 with 86 votes, #917 of 4,270 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 2 years on.
In plain words
Manta is an open-source, cross-platform tool for debugging and prototyping with FPGAs. Written in Python using Amaranth HDL, it works on any machine including ARM-based devices, unlike traditional vendor tools limited to Windows and Linux on x86 hardware. It enables users to read and write FPGA registers and memory while providing an integrated logic analyzer, with vendor-agnostic Verilog export capabilities. Designed for students and engineers seeking alternatives to proprietary debugging solutions.

LocalGPT – A local-first AI assistant in Rust with persistent memoryFeb 2026 · github.com · ▲331I 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:…
Claude Artifacts but creating real web apps2024 · gptengineer.app · ▲189Hey Hacker News! Launching gptengineer.app into beta today. It's like Claude Artifacts, but: - you can edit the code in your fav IDE (two-way github sync) - installs npm packages - automatically picks up build and runtime errors and fixes them - very fast, built with rust The full stack capabilities are built on supabase (prefer to not have to handle auth + user data at this point so this is owned by the user) The seed for this project was an open source experiment, posted about that previously here: https://news.ycombinator.com/item?id=36422730 Would love feedback if you give…
BiTE – Cross-platform executable viewer and reverse engineering tool2024 · github.com · ▲176Hey everyone! I’m excited to share a project I’ve been working on throughout my university studies. It’s called BiTE (https://github.com/WINSDK/bite) and it's a tool primarily focused on being an executable viewer with reverse engineering capabilities. BiTE supports Windows, MacOS, and Linux, along with their associated executable formats. It’s also capable of parsing and displaying debug information using DWARF/PDB formats, which I hope will be useful even for just comparing codegen. I’ve put a lot of effort into this and it's the first time I'm releasing something…

Talanoa▲345Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
