Write code, run builds, debug execution, and collaborate seamlessly across Java, Python, Go, Node.js, React, and Angular. Powered by Monaco Editor, an integrated cloud terminal, and autonomous AI pair programming.
Everything modern engineering teams expect from a desktop IDE, accessible from any browser with zero setup.
Full language server protocol (LSP) integration providing semantic syntax highlighting, smart code completions, hover documentation, parameter hints, and go-to-definition.
Pair program with an intelligent agent capable of multi-turn code generation, refactoring, bug remediation, project scaffolding, and explaining complex architectural logic.
Full PTY Linux terminal execution for running build tools, package managers, custom test runners, Git commands, and shell scripts directly within your workspace.
Set breakpoints, step into functions, inspect call stacks, evaluate variable scopes, and analyze runtime memory states with standard Debug Adapter Protocol support.
Clone repositories, manage branches, inspect commit histories, view three-way diffs, stage hunks, and push changes to GitHub, GitLab, or private Git servers.
Design modern web user interfaces visually with drag-and-drop components, responsive layout previews, data binding, and clean production code generation.
Switch seamlessly between writing server APIs, creating reactive frontends, and running terminal test suites.
