URL Alchemist

URL Alchemist for Chrome 2.0 URL Alchemist is a Chrome extension for building browser workflows from visual blocks. Create editable workspaces, compile them into portable binary Action Packs, and run those packs from page input data, hotkeys, context menus, intervals, or visible overlay events. What it can do Clean tracking links, rewrite URLs, search selected text, launch from clipboard text, capture page title or metadata, fetch HTTPS remote data, show messages and media in page overlays, copy structured output, and keep local per-pack logs. Workspaces and Action Packs Workspaces are the editable source files. They store the full block graph, trigger settings, metadata, and saved editor viewport. Action Packs are the optimized binary runtime files that Chrome executes. You can export either format: share a workspace when someone should edit the source, or share an Action Pack when they only need the reviewed runtime package. Safer imports Imported Action Packs are staged before install. URL Alchemist validates their schema, recomputes permissions and risk metadata, explains the compiled steps in plain language, and keeps the Confirm Import button locked until the pack is tested in the sandbox or explicitly reviewed. Action Packs cannot run imported JavaScript, eval, or downloaded code. Current Chrome 2.0 highlights - Visual workspace editor with drag-and-drop blocks, saved pan and zoom, recovery drafts, and pop-out editing. - Run on input data from URL, selected text, link URL, page title, clipboard, page text, page links, page metadata, and related sources. - Per-pack hotkeys recorded in the editor and matched by the content-script key listener. - Remote data and asset blocks with HTTPS-only validation, byte limits, timeouts, and private-network blocking. - Overlay-first interaction blocks for prompts, messages, image/video/audio display, input capture, keyboard events, mouse events, tick handlers, shared state, and grid drawing. - Debugging tools including trace, per-pack logs, Save string to log, Abort, and uninstalled-file audit. - Local-first backup and restore for settings, workspaces, Action Packs, metadata, and checksums. Built-in examples The Examples tab includes practical packs and workspaces such as Clean Campaign Links, Keep Stable Query, GitHub PR Files Shortcut, Search Selected Text, Clipboard Search Launcher, Remember Current Page, Copy Page Title, Debug Page Logger, Research Note Snapshot, Remote Text Fetch Preview, Remote POST Snapshot, Clean Words, Break Reminder, Playback Resume, Overlay Input Capture, and Snake Overlay Arcade. Examples are never installed automatically; you choose whether to install the compiled pack or open the workspace source. Privacy and control URL Alchemist stores data locally by default. Google Sync is optional and best-effort for small items. Clipboard access is optional. Local file navigation is disabled by default. Clipboard, raw page, remote request, page mutation, and overlay input behavior is surfaced as risk information before install. Build the browser workflows you actually need, inspect what they do, and keep control over how your tabs, URLs, page data, and overlays behave.

Custom Blocks now retain their selected Block Library category, new sources start explicitly uncategorized, the generic Custom category is no longer selectable, Workspace Name and Version are the single installed identity, and input/output ID, label, type, and tooltip stay synchronized in both editing directions. Installed or embedded metadata refreshes existing caller nodes without overwriting caller field values; renamed port IDs block compilation until explicitly reconnected. Field visibility and all tips are honored, and compilation rejects stale categories or mismatched Custom Input/Output boundaries instead of silently producing an inconsistent block. V1 `.urlpack` import/conversion and older V2 migration paths remain available. Fixed: - Selected-match and before/after replacements previously re-ran the regex on `match[0]`. - IPv6 prefix checks accidentally rejected ordinary domains beginning with `fc`, `fd`, or `ff`. Those checks now apply to IPv6 syntax. Link-local detection covers the full `fe80::/10` range; trailing-dot local names and `*.localhost` are rejected. - Content Blocker allowances previously did not work without `storage.session`. They now use the same fallback store, retaining compatibility with both previous browser-specific allowance value shapes. - Fallback guard-page URLs omitted challenge tasks, allowing the page to present immediate continuation. They now carry the configured tasks. Malformed task data fails closed. Guard-page tests verify that a configured confirmation task must complete before continuation becomes enabled. - Inactive overlays are deleted instead of retaining an inactive record. ############################################ Version 2.7.2 New Features / Changes ########################################### ⁃ Removed the generic “Custom” category from selection and display. Legacy blocks using it are unavailable until recategorized. ⁃ Made Workspace Name and Version the sole editable identity fields. ⁃ Preserved category, description, tips, visibility, fields, and port metadata. ⁃ Added bidirectional ID, label, type, and tooltip synchronization between metadata and Custom Input/Output nodes. ⁃ Refreshed installed block metadata without overwriting caller values. ⁃ Fixed Content Blocker dependency validation and custom-block risk propagation. ############################################ Version 2.7.1 New Features / Changes #######################################…
