Hey Product Hunt! 👋 I'm David, a solo dev from Prague. DevCleaner exists because of a ritual every developer knows: macOS says "your disk is almost full," and the culprits are always the same — DerivedData, Gradle caches, npm's attic, simulators for iOS versions you dropped a year ago. Existing cleaners treat your SDK like a temp folder. That's how weekends die. So I built DevCleaner around one idea: the risk level is the product. 🟢 Safe — pure caches that regenerate on your next build. Pre-selected, one click. 🟡 Warning — things that grow back slowly (old simulators, downloaded LLM models). Measured, visible, never pre-selected. 🔴 Danger — SDKs and device symbols that can break your environment. DevCleaner shows their size and never touches them on its own. The thing that surprised me while building it: AI apps are the new cache hogs. Cursor was quietly sitting on 1.3 GB on my machine, Claude's updater keeps full copies of old versions, Ollama hoards every model you've ever pulled. DevCleaner covers 22 ecosystems — the classics plus Claude, ChatGPT, Cursor, Windsurf, Gemini CLI, Ollama and LM Studio. Conversations, logins and settings are never touched. Also in the box: live "reclaimable space" badge in the menu bar, background scans, optional auto-clean with age filters, 30-day history with charts. One experiment I'd love your take on: after each cleanup the app can add a single anonymous number — bytes freed — to a community counter. No paths, no IDs, no IP stored, one toggle to turn it off. When the community passes 1 TB, the counter goes live on the site. It's free: no account, no trial, 4 MB, notarized, auto-updates. macOS 14+, Apple Silicon & Intel. Next up: Docker (the biggest disk hog of them all) and a finder for dead node_modules. Tell me what your favorite tool hoards and I'll add a scanner for it. 🧹
