In their own words
CodePair by CodeSubmit
CodePair by CodeSubmit runs live coding interviews in a browser-based shared IDE, terminal, and repository. Hiring teams can observe how candidates write code and collaborate in an engineering-style project. Candidates may use ChatGPT, Claude, Gemini, and coding-agent workflows, while reviewers see prompts, responses, actions, and accepted edits. The terminal provides bash or zsh, Nix packages, language runtimes, PostgreSQL, and Redis. CodePair says reproducible Nix environments cover more than 100 languages and 1,000 packages and services. Git history, branches, shared commits, pull-request simulation, diffs, merge-conflict resolution, and GitHub or GitLab repositories support repository work. Automatic port detection, live reload, concurrent services, database connections, and preview links support running projects. Integrations include Greenhouse, Lever, Personio, Ashby, Zapier, Slack, and an Enterprise API. Plans start at $49 a month, billed monthly, with a seven-day trial.
Duckly
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.
