Your complete developer platform
Everything you need to build, document, and operate developer tools. From CLI to API to SDK -- it's all here.
Powerful CLI
Interactive command-line interface with autocompletion, progress bars, and beautiful output. Installable via npm, brew, or curl.
RESTful API
Well-designed REST API with OpenAPI spec, versioning, and comprehensive error handling. Auto-generated client libraries.
SDKs & Libraries
Official SDKs for Node.js, Python, Go, and Ruby. Type-safe, well-documented, and published to package registries.
Interactive Docs
MDX-powered documentation with live code examples, API playground, and full-text search. Deployable as a standalone site.
Monitoring & Alerts
Real-time health monitoring, error tracking, and alerting via Slack, email, or PagerDuty. Detailed request logs and analytics.
Integrations
Pre-built integrations with GitHub, GitLab, Slack, Jira, and more. Webhook support for custom integrations.
Ship your CLI in minutes, not months
Our CLI framework handles argument parsing, configuration management, plugin systems, and automatic updates. Focus on your tool's logic, not the plumbing.
Documentation that developers actually read
Interactive code examples, API reference auto-generated from your OpenAPI spec, and a built-in search engine. Your docs deploy alongside your API.
Observability from day one
Structured logging, distributed tracing, and metrics collection preconfigured. See every request, track every error, and set alerts before users notice.

CTO
“The monitoring and alerting setup caught a critical issue in staging before it ever reached production. Saved us a very bad weekend.”
Sarah O'Connor
Platform Engineer
“Clean architecture, excellent TypeScript support, and a plugin system that actually makes sense. This is how dev tools should be built.”
