The Problem

Setting up a working development environment is still one of the slowest parts of starting a project or onboarding an engineer. Local toolchains drift, machines differ, and the gap between "works on my machine" and a reproducible environment costs teams real days.

RunCode was built to move that environment into the browser: a consistent, shareable workspace with the languages and tooling already in place, so the work starts immediately rather than after a day of setup.

What We Built

  • browser-based coding workspaces with persistent state
  • support for multiple programming languages and runtimes
  • collaboration workflows across a team
  • AI-assisted coding features inside the editor
  • workspace lifecycle and resource management
  • SSH access into running workspaces

Relevant Service Lanes

RunCode had to behave like a real development machine rather than a toy editor, which means process isolation, persistent workspaces, and performance that holds up under concurrent users.

Why This Was More Than an Online Editor

RunCode had to behave like a real development machine rather than a toy editor, which means process isolation, persistent workspaces, and performance that holds up under concurrent users.

running untrusted user code safely with strong isolation

keeping editor latency low while work executes remotely

managing workspace lifecycle so idle compute does not burn cost

supporting many language runtimes without a bloated base image

making collaboration feel immediate rather than eventually consistent

Outcome

  • live in production at runcode.io
  • supports multiple languages and runtimes in one platform
  • AI-assisted coding built into the workflow rather than bolted on
  • used as a working proof of our own cloud and container engineering
