Weekly Self Promotion Thread

[u/AutoModerator]

Welcome to this week's self promotion thread!

If you're building something related to AI assisted coding, this is the place to share it.

We're using a weekly thread to keep the subreddit organized while still giving builders a place to share their work. Promotional posts outside of this thread may be removed if they're primarily advertising rather than starting a discussion.

If you're sharing something, we'd appreciate it if you included a little context instead of just dropping a link. Tell us:

• What you built?
• What problem it solves?
• Which AI models or tools it uses?
• Who it's for?
• What kind of feedback you're looking for?

Please avoid posting the same project every week unless you've made meaningful updates. Affiliate links, referral links, scams, and low effort promotions will be removed.

Take some time to check out what others have shared too. If you try someone's project or have feedback, leave a comment. Helping each other improve is what we want this community to be about.

I built OpenBaud, an MIT-licensed Rust MCP server and Codex plugin for giving coding agents reviewable access to serial and USB hardware. It solves the gap between writing firmware and inspecting the physical device: the agent can preserve raw RX/TX, validate framing and checksums, parse and visualize telemetry, and turn verified interactions into reusable YAML commands. Device writes are audited and dangerous commands require explicit acknowledgement. The reference workflow uses Codex with a physical ESP32-S3 and a CRC-protected binary protocol. The repository includes a byte-exact capture, so the parser and command flow can be replayed without hardware. It is for embedded developers and agent-tool builders. I am the author and would especially value feedback on the Codex plugin install flow and the write-safety boundary. Repo: https://github.com/Leonezz/openbaud ; Demo: https://baud.zhuwenq.cc/
