24 alternatives to Fully offline, open-source alternative to Scribe for Firefox
I had to do a bit of web-workflow documentation and found the process of gathering screenshots, placing them correctly into a document, and creating captions extremely tiring. I figured it’ll be easy to automate and also a great opportunity to get to know the Browser API, and here we are with the first release of the extension. It’s extremely easy to use but barebones which I plan to change in the near future, so any feedback will be appreciated. I want to keep the docs generation process completely offline to avoid dealing with server costs and GDPR stuff which poses a lot of challenges…

Last time I posted this it didn't garner much interest. There have been lots of improvements and fixes since the last release. Quick list of features: - Workspaces - Tabs - Nested Folders - Lots of context menus - Response history - Plugins - Runs fully in the browser and runs offline if necessary - Chrome and Firefox extension to bypass CORS restrictions - Desktop builds for all platforms - GraphQL support - Import collections exported from Postman and Insomnia - Simple user friendly interface I built this because I love Insomnia but wanted a portable version that I could run in the…

BreezePDF lets you edit, sign, merge, compress, redact, OCR, fill forms, extract tables, and use 30+ more PDF tools — all in the browser, no sign-up. Files never leave your computer. I built it because when people search Google for common PDF tasks, many of the tools they find upload documents to a server. I wanted an option that keeps files local instead. I posted an earlier version on HN last spring: https://news.ycombinator.com/item?id=43880962 At the time it only supported a small set of features. Over the last 10 months I rebuilt large parts of it and expanded it to…

Hey everyone, for the past like six months I've been working on a portfolio project. I got tired of doing easy projects, so I decided to tackle something bigger and more challenging. That's when I came up with the idea of a video editor. This piece of work is intended to showcase my skills and land me a job, but I like to think when working on projects that my idea is so cool that people will like to use it, and I treat every project like a startup idea. Also I havent seen many open source video editors especially on web so that was one of the points why I decided to make that and not…

Inspired by the design and UI/UX of apps like Notion, and utility of open-source apps like StackEdit, I decided to create a minimalistic, local-only WYSIWYG Markdown editor. Some features worth highlighting: - Monaco editor and Prettier integration for code snippets - Tables (apparently the holy grail of WYSIWYG editing) - Embeds (for CodePen, CodeSandbox and YouTube, most useful for HTML or JSON exports) - Accepts Markdown paste-in, and "exports"/generates HTML, Markdown and JSON outputs - Collaboration (with real-time awareness and initial commenting system, available only when…

Sometimes you might want to share a screenshot of the website you're on, without revealing the personal data that is visible at that time. With Obfuscate, you can make text unreadable without changing the structure of the web page. Hit the extension button or press Alt+Shift+O to activate for the current page. (Note that extensions can't modify the add-on website, so trying it on there won't work.) Credit for the original idea: https://chaos.social/@maris/108379386421123630

We needed a JS-first WYSIWYG DOCX editor and couldn't find a solid OSS option, most were either commercial or abandoned. As an experiment, we gave Claude Code the OOXML spec, a concrete editor architecture, and a Playwright-based test suite. The agent iterated in a (Ralph) loop over a few nights and produced a working editor from scratch. Core text editing works today. Tables and images are functional but still incomplete. MIT licensed.

We are working on an open-source .docx editor library for apps that need to edit Word documents in the browser. We just shipped 1.0. A lot of existing approaches convert .docx into HTML and lose document semantics along the way. Our editor parses OOXML directly and uses its own rendering+layout engine to produce paged documents with html/css. Edits round-trip back to .docx, so you’re always editing the document, not its representation. The core rendering engine is framework agnostic, with React and Vue ui adapters on top. It’s Apache 2.0. Happy to answer questions.

This is the entire Firefox browser rendering to a element. Gecko, all UI components, and the Spidermonkey JS engine are all compiled and running in WebAssembly. Here are a few things you might find interesting: - This is fully end to end encrypted! We use the WISP protocol for TCP-over-websockets. - There is a novel WASM->JS JIT for experimental site speedup - This port cost over 25k in opus/fable tokens for debugging and JIT research This was just a fun experiment to push the boundaries of WebAssembly. For a more usable "browser in browser" experience, we also built…

Hey HN, I made Browser-Use, an open-source tool that lets (all Langchain supported) LLMs execute tasks directly in the browser just with function calling. It allows you to build agents that interact with web elements using natural language prompts. We created a layer that simplifies website interaction for LLMs by extracting xPaths and interactive elements like buttons and input fields (and other fancy things). This enables you to design custom web automation and scraping functions without manual inspection through DevTools. Hasn't this been done a lot of times? Good question, as a general…

I built a web-based HTML/CSS/JS editor focused on speed, simplicity, and offline access. No bloat — just open and start coding. What makes it different: Live Preview – Edit HTML, CSS, and JS side-by-side with instant feedback. Offline support – Works without internet. You can even install it as a PWA and use it like a native app. No Login Required – Just visit, code, and preview. Login only if you want to save/share. Savable & Shareable Links – Save scripts in the cloud and get shareable links. Customizable Editor – Themes, fonts, auto-format on save, layout tweaks, line…

We're open-sourcing 14 components & examples today for PDF, DOCX, and XLSX viewers, plus bounding box citations, file upload, e-signature, and more. It's MIT licensed and fully customizable. Demo video here: https://share.extend.ai/kRmSGKRF When we started, we tried every file viewer and document component library we could find. Unfortunately, none of them had all the functionality (and polish) that we wanted, so we ended up building our own for https://extend.ai/. It was only ever meant to be internal, but enough customers kept asking for it that we decided to…

I just realized you can now open a PDF document in Firefox and select text directly from scanned images embedded in the document (so basically transparently reliable doing OCR). It is also surprisingly reliable, only sometimes mistaking a "oh" for a "zero" in a long string of numbers. I neither know when this was introduced nor who added this feature, but from the bottom of my heart: thank you, thank you, thank you, you have made my daily life a lot easier. I also haven't really explored the limits of the feature and under what conditions it starts failing, but: in my daily workflow so far,…

Introducing QuaranTab: Companion extension to quarantine tabs so you can safely use them offline with private data I find myself wanting to use online format parsers to quickly decode that production JWT or decode a base64 Authorization header but cannot trust these websites to not leak my information. I thought to myself if only I could cut-off network access to this site, use it offline, and then throw away all browsing data. So I created an extension just for that. It uses Firefox contextual identities API (Containers) to isolate browsing data and inter-tab communication. Once the site is…

AlliHat▲96I think we all have a similar flow and pain with browsers and AI. Copy article, paste in Claude tab, come back to article, back to Claude, in circles we go. Anthropic has a Chrome extension, but my daily driver is Safari. So I made my own extension. It's not a clone as I've never used the Chrome version. One obvious change: the Chrome version I believe uses Chrome "request sidebar" thing. And Safari doesn't have that, so had to inject the sidebar right in the site html itself. There's been some fun things in here like figuring out the sidebar html/css sandboxing. Also there's an agent…
