Browser Extension · Coming soon
112 Zerethon Tools
one click from your toolbar
A privacy-first browser extension launcher for every tool at tools.zerethon.com.
Search, favorites, right-click context menu, omnibox keyword zt.
No analytics. No tracking. Open source.
Searchable launcher
Click the toolbar icon or hit Ctrl+Shift+Z to fuzzy-search all 112 tools by name, slug, or keyword.
Right-click prefill
Select text on any webpage and right-click → "Zerethon: Format as JSON" / "Decode Base64" / "Hash" / "Convert case…" / "Parse URL". Input prefilled, ready to run.
Side panel
Pin the launcher to Chrome's side panel and keep it visible while browsing. Switch tabs without losing your place.
Address-bar omnibox
Type zt regex in the address bar → live suggestions → Enter opens the tool.
Favorites + recents
Star tools to pin them. Recents auto-track your last 8 opens. Both stored on device — favorites sync across your Chrome devices via Google's own infrastructure.
Privacy-first
Zero analytics, zero telemetry. Only 3 permissions, only one host (tools.zerethon.com). Open source — audit every line.
Privacy policy.
Get notified the day it ships
One email when v0.1 is live on the Chrome Web Store. No newsletter, no follow-ups, no sharing your address with anyone.
Why an extension at all?
Because typing "json formatter" into Google and clicking the first non-sponsored result every time gets old. The extension puts tools.zerethon.com one keystroke away from any tab.
Do tools run offline in the extension?
Not in v0.1 — clicking a tool opens it on tools.zerethon.com in a new tab. v0.2 will bundle the most-used tools (chosen from real usage data) to run fully inside the extension with no network access.
What data does it collect?
None that leaves your device. Recents and favorites are stored locally. There is no analytics SDK, no telemetry endpoint, no third-party requests. Full disclosure in the privacy policy.
Is the source open?
MIT-licensed at github.com/zerethonapp/extensions. Builds are reproducible — the byte-identical zip we submit to the store comes out of npm run build.
