Free developer utilities. Native. Offline. One Cmd-key away.
A free macOS menu-bar app with 13 built-in tools and a Spotlight-style launcher. Hit ⌃ ⌥ Space from anywhere, paste, get the answer. No web tabs. No telemetry. No account.
13 tools that should already be on your menu bar.
Every tool runs locally. No paste boxes that ship your auth tokens off to a stranger's analytics endpoint.

Built for the way you actually code.
Menu-bar resident. Keyboard-first. Smart enough to read your clipboard before you ask.
Spotlight-style launcher
Press ⌃ ⌥ Space from any app. DevTray inspects your clipboard, guesses what you're holding (JWT? JSON? UUID?), and jumps straight to the right tool — pre-filled.
Snippets that actually scale Pro
Save once, find from anywhere. Full-text search across title, body and tags. Pinned snippets surface in the launcher. Export to JSON, sync however you like.
100% local. Zero telemetry.
Tokens, snippets, inputs, everything stays on your Mac. No background uploads. No analytics. The only network call DevTray ever makes is the license check on launch.
Auto-update via Sparkle
Code-signed with an Apple Developer ID, notarized by Apple, stapled, Gatekeeper-clean. No "right-click → Open" theatre. Updates land quietly through Sparkle.
