CodeCollab vs Duckly

CodeCollab is a browser-based shared workspace for pair programming, technical interviews, teaching, and team brainstorming. Rooms provide real-time multi-cursor editing with shared cursors, selections, and keystrokes. The editor offers syntax highlighting, bracket matching, and language-aware indentation for 15 languages. A shared canvas can sit beside the code for architecture sketches, flows, and other ideas. Users can share secrets protected at rest with AES-256-GCM, expiry timers, and instant revocation. Connections use HTTPS and negotiate TLS 1.3 with compatible browsers, but secrets are not end-to-end encrypted because CodeCollab holds the key. Code is not compiled or executed on the service. Unclaimed rooms are deleted after seven days; claimed rooms remain until deletion or account closure. The Free plan costs nothing, while Pro costs $49 a month. CodeCollab is operated by Zeppl Studios in Lisbon.

Duckly is an IDE plugin for real-time collaboration between developers using different development environments. Multiple developers can work in the same file through shared code, while audio, video, screen sharing, chat, and terminal sharing run alongside the IDE. Terminal integration installs through npm, and write access can be enabled with the `duckly share --w` command. Listed editors include VS Code, VS Codium, and IntelliJ-based tools such as WebStorm, PyCharm, PhpStorm, CLion, Rider, RubyMine, AppCode, Android Studio, DataGrip, and GoLand; a Chrome extension is also listed. Duckly says IDE files are shared peer-to-peer with end-to-end encryption and do not pass through its servers. Calls and chat with four or fewer participants use peer-to-peer end-to-end encryption; with a fifth participant, calls switch to cloud infrastructure. The Free plan costs nothing and allows two participants without video calls. Hacker costs $6 a month for three participants; Team costs $10 per member per month for up to 60.
