Ask HN: What are you working on? (June 2026)
Points and comments are a snapshot, not live.
Monthly thread collecting projects developers are building, ranging from search engines to health trackers.
This is Hacker News's monthly "What are you working on?" thread. Participants share active projects across domains: gmd, a local markdown search tool with vector and hybrid search; MacroCodex, a free calorie tracking app with 13,000+ users that adapts maintenance calorie estimates; Peak Flow Meter Diary, an asthma tracking app correlating readings with environmental data; Totem, a Rust-based collaborative knowledge management system for Windows, macOS, Ubuntu, and iOS; HN Alerts, an email notification service for trending Hacker News stories; a film-to-music curation site; database schema isolation tooling for PostgreSQL and MySQL; Kavla, a SQL canvas with agent integration; OpticSketch, a 3D optics simulator; and Uruky, an EU-based privacy-focused search engine alternative that reached 150 monthly active accounts.
What commenters are saying
Commenters offered practical feedback and encouragement. One user flagged a broken Terms of Service link for Totem, which the developer fixed before iOS review. A commenter noted sync rights and copyright law considerations for the film editing project, though another claimed fair use coverage. Uruky's developer reported reaching 150 monthly active accounts (up from 100) and disclosed upcoming features like Monero payment support and voucher partnerships. A supporter expressed interest in Uruky becoming a sustainable business. Technical questions surfaced about HN Alerts' rollup behavior and OpticSketch's free demo availability, both answered directly by authors.
