Dev Toolkit Ali Houshyari Pour توسط

Dev Toolkit collects the small utilities you keep reaching for into a single panel, so you stop installing six add-ons to get them.

Web font override — replace the font on any page, while leaving code blocks and icon fonts untouched. Adjustable base size and line height.

Text direction — force a page right-to-left or left-to-right, or restrict it to input fields only when you do not want to disturb the layout.

Tab masking — swap the title and icon of your tabs for a neutral placeholder before you share your screen, so a recording or a passer-by does not reveal what you are reading. One keyboard shortcut toggles it, and you can mask every tab or only the background ones.

JSON viewer — JSON responses become a collapsible tree with search and match highlighting, jq-style path copying, a raw view, key sorting and a download button. Large arrays are chunked so huge payloads stay responsive.

Garbled text repair — restores text that was stored as UTF-8 but read back with a single-byte encoding, the classic symptom of a mismatched database collation: علی becomes readable again. Display only; nothing is ever written back to your data.

Cache and cookie tools — clear one site's cookies, local storage, IndexedDB, cache storage and service workers, or clear the whole browser by time range. List, copy and export cookies as JSON, a Cookie-Editor file, a cookies.txt for curl, or a raw Cookie header.

Available in English and Persian, with a language switch inside the panel and automatic right-to-left layout.

No analytics, no telemetry, no network requests of any kind. Every setting stays on your device.
