In their own words
BrowserGap
BrowserGap is an open-source remote browser isolation solution for automation, security, privacy, and CBII. It runs a browser remotely and streams the page as pixels to a browser interface on the user's device, so the page's HTML, CSS, and JavaScript do not execute there. Users can work with tabs, forms, file transfers, modal dialogs, incognito tabs, and session-data clearing. Developers can embed a BrowserView in another web app, connect Puppeteer, or use the VF.openSecurely(url) API method. BrowserGap can also expose automation activity so a person can intervene when a job needs input. It adjusts image resampling to available bandwidth. The project can be self-hosted from source or run in Docker; binary instructions require Google Chrome on Windows, Mac OS, or Linux. Secure document viewing with content disarm and reconstruction is supported, but the source-available edition requires users to set up the viewer. The community edition is free under stated in-house deployment conditions. A managed session is listed at $3.81, paid once.
Wren
Wren is a free, open-source, local-first reference manager for research on Apple Silicon Macs running macOS 14 or later. It handles more than 40 bibliographic item types and keeps PDFs, EPUBs, HTML snapshots, images, and notes as plain files. Built-in PDF and EPUB readers provide annotations, and highlights can be exported inside a PDF. Its Markdown editor supports mathematics, code highlighting, reference links, anchored comments, and automatic backlinks. Full-text and semantic search can point semantic results to source passages. On-device layout analysis, OCR, and table extraction process PDFs, including scans, offline. Libraries can sync through iCloud Drive, Dropbox, Google Drive, or another folder you already sync, without a Wren account or Wren servers. A Chrome connector captures references, PDFs, and snapshots. Optional bring-your-own-model AI supports several providers and local use. Wren also offers a local REST API, deep links, and bibliographic import and export.
