What is Codeground AI?
Seven products, one tab, zero setup.
Most dev work needs an IDE, a runtime, an interview tool, live video, structured learning, micro-utilities — and the occasional mental reset. Codeground AI bundles them into one product so your tools never get in your way.
Online IDE that just runs
A full Monaco-powered editor with syntax highlighting, autocomplete and one-click execution in 15+ languages. Hit Run, see output. That’s it.
Open the editorCloud Workspaces
Spin up persistent, container-isolated dev environments from a template or a Git repo. File tree, multi-tab editor, real terminal, live logs — pre-configured and ready to ship.
Launch a workspaceInterview Platform
Remote coding interviews for startups: shared Monaco editor, Ground Call video, integrity monitoring (tabs, focus, desktop share), and structured scoring — without enterprise pricing.
Explore interviewsGround Call
Host browser-based video calls built for pair programming and remote interviews. Start a room in one click, share the link, screen-share your editor, and switch between grid, spotlight, sidebar, or gallery layouts — no install required.
Start a callInteractive Courses
System Design Dojo plus language tracks — sketch architectures for AI critique, or learn with guided lessons and runnable code in the browser.
Browse coursesDeveloper Toolbox
JWT Debugger, AI Code Detector, Epoch Converter, JSON Diff, Base64, Regex Tester and more — every micro-tool you Google, in one place.
Browse all toolsDev Break Arcade
Quick browser games for when your brain needs a reset — snake, flappy, breakout, endless driving, and chess. No install, no account, just play and come back sharper.

How it works
From “I have an idea” to “it’s running” in 10 seconds.
Pick a stack
Choose from 15+ language and database playgrounds. Your environment is provisioned in real Docker containers.
Code in the browser
A Monaco-powered editor with autocomplete, multi-file tabs, AI assistance and a real Linux terminal alongside it.
Run, share, ship
Hit Run for instant output. Share a link, invite collaborators, or take it to interview, evaluation or production.
Languages & runtimes
Pick a stack. We boot it for you.
Every ground runs in a real, sandboxed container — not a wasm shim. So your dependencies, package managers and shell behave exactly as they do locally.
Cloud workspaces
A real dev environment, in a tab.
Launch a workspace from a template or import a Git repo. You get a multi-tab editor, a real terminal, dependency installs, persistent files and live runtime logs — already wired up.
- Import any public Git repo or start from a template
- Real Linux terminal with package managers and apt-style installs
- Run servers and view live logs without leaving the workspace
- Container-isolated, so no two workspaces collide
- Persistent files — pick up where you left off, anywhere
Interview platform
Run fair, secure technical interviews — without juggling four tabs.
A coding interview tool built by people who actually take coding interviews. Live editor, video, chat, timer and an evaluator-grade anti-cheat engine, all in one screen.
- Tab-switch, focus and copy-paste detection
- Eye-attention monitoring & full-screen enforcement
- Multi-question sessions with structured rubrics
- Live chat + collaborative editor + per-question timer
- Auto-generated evaluation report you can export and share
Developer toolbox
Stop Googling tiny tools. They live here.
JWT debugger, AI code detector, epoch converter, JSON/SQL utilities and more — kept in one neighbourhood. Free. Fast. No popups.

Frequently asked questions
Everything you’d want to ask before signing up.
Node.js, Python 3, Java, C++, Go, Rust, TypeScript, React (JSX), Ruby, Lua, Groovy, Bash, plus full HTML/CSS/JS with live preview, and database playgrounds for MongoDB, PostgreSQL, MySQL, Redis and ClickHouse — all running in real Docker-isolated containers.
Persistent, container-isolated dev environments you can launch from a template or a Git repository. They bundle a multi-tab editor, real terminal, dependency management and a live runtime — so you can ship without installing anything locally.
Create a session, share a link, and run a live coding interview with Monaco + Ground Call video. Integrity monitoring covers tab switches, focus loss, copy/paste, fullscreen, and full-desktop screen share (browser tabs are rejected). Interviewers get a live integrity feed. An Integrity Agent for OS-level AI-assist detection is coming on Pro. Candidates need no account.
All execution happens in sandboxed Docker containers. Your code is not permanently stored unless you explicitly save it. Authentication uses industry-standard JWT, and private projects support access controls.
Most programs return output in under 2 seconds. Codeground runs on optimised infrastructure with concurrent execution, so multiple users — and multiple workspaces — run independently and quickly.
