Freshet

About

Freshet turns any JSON URL into a rendered page. Write one small Liquid template per URL pattern, and from then on, responses from that endpoint render as a real dashboard — fields surfaced, statuses chipped, IDs turned into clickable links to whatever they reference. Same URL, proper UI.

Built for people who live in internal tooling, debug webhooks, or hit API endpoints directly in a browser tab. If you've ever squinted at a wall of <pre>-formatted JSON trying to find the one field you cared about, this is for you.


★ WHAT YOU GET ────────────────────────────

• Per-URL rules with glob patterns (*.server.com/api/**) or raw regex — first-match-wins, reorderable.

• Liquid templates — {{ path.to.value }}, conditionals, loops, and helpers for dates, links, and compact numbers. No JavaScript in templates. No eval.

• A URL tester in the options page that tells you exactly which rule matches (or why the others don't — host-miss, path-miss, shadowed).

• A real template editor — CodeMirror 6 with Liquid syntax highlighting, autocomplete over your sample JSON's paths, and a live sandboxed preview.

• A top strip on every matched page — env chip, Rendered / Raw toggle (⌘⇧J), Copy URL, Edit rule, Skip this host. Isolated in a shadow DOM so it can't collide with the page.

• Five bundled starter templates — service health, incident detail, GitHub repos, Pokémon, and country data. Try them out of the box at mattaltermatt.github.io/freshet/try/

• Dark mode from day one, and WCAG 2.1 AA on every surface.


★ SAFE BY DEFAULT ─────────────────────────

All Liquid output is auto-escaped. A second-pass sanitizer strips <script>, <iframe>, inline event handlers, and javascript: / data: / vbscript: URLs. Template previews render in a sandboxed iframe with no same-origin access. Freshet makes no network requests of its own — it only reads JSON that Chrome has already fetched for you.


★ PRIVATE BY DEFAULT ──────────────────────

Your rules and templates live in your own chrome.storage — synced across your signed-in Chrome devices, or local-only if your config exceeds the 90 KB sync budget. No telemetry. No analytics. No external hosts contacted. Full privacy policy: mattaltermatt.github.io/freshet/privacy/
