Why ReasonOS?
Modern development teams juggle dozens of tools — build systems, CI/CD platforms, infrastructure tools, linting frameworks, container builders, and more. RBS replaces all of them with a single, unified platform.The problem with today’s tooling
Tool sprawl
Teams manage 10–20+ separate tools for builds, tests, CI, infrastructure, containers, linting, and deployment — each with its own configuration format and maintenance overhead.
Slow onboarding
New engineers spend days or weeks setting up local environments. “Works on my machine” remains the most common debugging excuse.
Fragile CI pipelines
YAML-based CI configurations are brittle, hard to test locally, and disconnected from the build system. A passing local build doesn’t guarantee CI success.
No collaboration
Developers work in isolation. Code review is asynchronous. Pair programming requires third-party screen sharing. There’s no shared understanding of what’s happening in the codebase.
How RBS solves it
RBS is a managed cloud development platform that consolidates building, testing, deploying, linting, infrastructure provisioning, container building, and real-time collaboration into a single tool — all accessible from your code editor.One tool, not twenty
Replace Bazel + Jenkins + Terraform + Docker + ESLint + Prettier + Slack + Zoom + GitHub Actions with a single
rbs command.Zero local setup
Every branch gets a dedicated build server in the cloud. Open your editor, connect, and start building. No local toolchains, no Docker, no environment issues.
Hermetic by default
Every build is reproducible. RBS manages all toolchains — compilers, runtimes, formatters, linters — in isolated, versioned environments. No system dependencies.

What teams are saying
Replaced 12 tools with one platform
“We eliminated GitHub Actions, Terraform, Docker, ESLint, Prettier, Slack for dev chat, Tuple for pairing, and more. Our engineers now have one tool to learn and one place to work.”
Onboarding went from days to minutes
“New engineers clone the repo, open their editor, and connect to RBS. No local setup, no Docker compose, no environment variables. They’re productive on day one.”
CI that actually matches local builds
“With RBS, there’s no difference between a local build and a CI build. The same hermetic environment runs everywhere. ‘Works on my machine’ is a thing of the past.”
Key differentiators
SDK-first extensibility
Define custom build rules, linters, and toolchains using the RBS DSL. No plugin systems, no package managers — just configuration.
Managed build servers
Every branch gets a dedicated server. Builds run in the cloud with shared caching. Your laptop stays cool.
Real-time collaboration
Edit code together, video call, screen share, and chat — all built into the platform. No third-party tools needed.
AI-powered development
A built-in coding agent that understands your builds, modifies code, runs tests, and coordinates multi-agent teams.
Hermetic everything
Toolchains, dependencies, linters, formatters — all managed and versioned. Builds are reproducible across every environment.
Any language
Python, Java, Node.js, TypeScript, Kotlin, Go, C/C++ — all with managed toolchains and consistent build rules.
