Pinako vs Sidebery

Pinako is a browser extension for organizing tabs and sessions in nested trees and restoring closed tabs and windows to their earlier positions. Libraries collect tabs, windows, and notes, including shared workspaces. Notes support rich text; Pro+ adds resizable image, video, and audio embeds stored in Pinako cloud. Search includes natural-language queries and an AI Librarian chat panel, while an MCP bridge connects desktop AI clients and runs locally. AI Search sends the query and relevant context to xAI's Grok API. The free extension stores data locally; the privacy policy says Pinako does not sell data, read page contents, or train AI models on stored data. Backups can use local snapshots or optional services including Google Drive, Dropbox, Filecoin, Arweave, and Storj. The Free plan is free. Pro is $5 a month, Pro+ is $10 a month, Premium is $25 a month, and Enterprise is $60 a month. New subscribers can try Pro and Pro+ monthly plans for 14 days without providing a payment method.

Sidebery is a free Firefox extension for managing tabs and bookmarks in a sidebar. Its panels can display tabs, bookmarks, and browsing history, with tabs shown as a flat list or tree. Users can group tabs under custom names, color and sort them, and automatically unload folded branches or inactive panels. Container features bind containers to panels, reopen URLs in selected containers, and set proxy or User-Agent settings. The extension also supports tab search, session restore, suspension, workspaces, snapshots, and optional cross-device synchronization. Context menus, mouse and keyboard controls, drag-and-drop behavior, and sidebar styles can be customized with variables and CSS. Data is stored locally by default; Firefox Sync or Google Drive can sync selected settings and tab data. The project is MIT-licensed. Firefox does not permit hiding the native horizontal tab bar, and some tab-moving add-ons may conflict.
