Show HN: Fork – Let users build features on top of existing applications Our initial release is a Chrome extension that builds on top of Gmail and Google Calendar. We keep limited trace activity of coding sessions for 30 days to troubleshoot and improve our offering. No data (events, emails) from Google is ever logged or retained. 50 second demo: https://www.youtube.com/watch?v=JQ292bncO_c Chrome extension (free + no login): https://ift.tt/NZ32wKX... We have a lot to learn and build. Would love any and all feedback! Paul & Dalton https://withfork.co/ July 7, 2026 at 11:47PM

Show HN: Record, replay, and improve AI agents in production https://ift.tt/6iwlevz

Show HN: Record, replay, and improve AI agents in production At the AI Engineering World's Fair a big part of the conversation was to nail the self improvement loop. Our take on this is to record state of the agent execution with a durable runtime, then allow users to replay from state checkpoints and run 'what-if' experiments. It's OSS and free to use. Would love some feedback from the community. https://ift.tt/kbJYScR July 6, 2026 at 10:56PM

Show HN: I built an encrypted BLE dongle for pasting stuff to air-gapped devices https://ift.tt/wWEK7xQ

Show HN: I built an encrypted BLE dongle for pasting stuff to air-gapped devices Definitely one of those "20 minute adventure gone wrong" projects where all I wanted initially was a quick wireless rubber ducky for bitlocker keys and the like and then I kept adding stuff like AES-256..... Currently working on adding WebAuthn/FIDO support because the hardware is already there and scope creep is a lifestyle at this point. Would love feedback, especially on the security side. Repo and PCB files are fully open source. https://ift.tt/XGDhpAd July 5, 2026 at 02:43AM

Show HN: Waypoint.nvim – A Neovim plugin for bookmarking lines of code https://ift.tt/qbOM0IJ

Show HN: Waypoint.nvim – A Neovim plugin for bookmarking lines of code I made this plugin because I felt like existing bookmark plugins were lacking some important features, including: - The ability to reorder your bookmarks - The ability to delete and move your bookmarks in bulk - The ability to view lines of code around your bookmarks - Syntax highlighting in the preview window - Resilience to the content of files changing (e.g. checking out a git commit that changes the file contents won't delete your bookmarks) Let me know what you think! If you have any feedback, please create a github issue or email patricksharp.dev@gmail.com https://ift.tt/GLUgpF8 July 5, 2026 at 01:25AM
