Every fix, feature, and improvement — in chronological order. We ship fast and document everything.
Preview your running app side-by-side with your code. Includes a DevTools panel, JS REPL, context menu, and hot reload on every save — no tab switching required.
50% off Pro for verified students and bootcamp learners. Apply at cloudpen.dev/students — approval within 24 hours.
Quill now reads your active file and open project structure before responding. Select any block of code to explain, debug, or refactor it without copy-pasting into a separate chat.
The in-editor panel now ships with tabbed DevTools — Network, Console, and Elements — alongside the JS REPL and hot reload controls.
Terminal sessions now reconnect automatically when a browser tab is restored from sleep instead of showing a stale or frozen shell.
Push to your GitHub repo and Cloudpen pulls the changes and redeploys your live URL automatically. No CI/CD pipeline configuration required.
Connect a custom domain to any deployed project with a single CNAME record. SSL is provisioned automatically at no extra charge.
Reduced sandbox cold-start time from ~4s to under 800ms by pre-warming container pools per runtime environment.
Deploy any project to a live cloudpen.dev subdomain in under 60 seconds — from first line of code to a public URL with automatic SSL.
Every developer now gets a public profile at cloudpen.dev/u/username — with pinned projects, contribution heatmap, follower/following counts, and a follow button.
Browse and fork public projects, discover public teams, and find developers to follow — all from the Explore page inside the dashboard.
Built-in AI assistant available to all users. Understands your current file and project context — not a generic chatbot bolted on top.
Pinch-to-zoom, swipe-to-indent, and a redesigned touch keyboard toolbar make coding on a phone significantly faster.
Cloudpen opens to everyone. Free plan with no time limit. Pro at $12/month — less than GitHub Copilot alone.
Connect your GitHub account and import any repo with one click. Branches, commits, and push access all work from inside Cloudpen.
Real shell access — not a simulated terminal. Run npm install, git, python, or any CLI tool exactly as you would on your local machine.
Every project runs in an isolated Docker container. Safe, consistent, and supports any runtime — Node, Python, PHP, and more.
One-click repo import and webhook auto-sync. Deploys that once took 20 minutes now take 10 seconds.
First cohort of users gets access. Mobile-first design validated immediately — over 40% of signups reported coding primarily on phones.
Cloudpen's first line of code. Two engineers frustrated with cloud IDEs that didn't work on mobile started building from scratch.
The team is heads-down building. Follow along on X for early previews and announcements before they hit the changelog.
Open a browser tab and get a full IDE, live terminal, AI assistant, GitHub sync, and one-click deployment — no installation, no setup, no credit card required.
