Introduction to Scalar
A modern API platform built for the OpenAPI™ standard.
Industry leading Developer Docs, SDKs, API Client & Registry that your APIs deserve
Take their word for it
"After years of helping enterprises implement API strategies at SmartBear, I can confidently say Scalar is what the industry has been waiting for. The strict OpenAPI compliance, robust CLI/API registry, and seamless CI/CD integration solve the exact pain points I watched customers struggle with daily. This is the modern API platform developers deserve."
Michael - Former Solutions Architect @ Smartbear
"One of my most recent favorites is a in-browser ad hoc testing UI called Scalar. One of the things that I really love about Scalar, it's got this modern UI experience, and it provides built-in test generation code for a variety of targets, from cURL to HttpClient in C#."
Captain Safia - Engineer @ Microsoft ASP.NET
"Scalar's "golden ticket" is... Scalar! They are (in my own words) building a product ecosystem for API design, docs, testing, and governance- with offerings at every price point. They are open source. So I can get in on free features and stay with Scalar no matter how big my API needs blow up."
Eron - Documentation Engineer @ Qrvey

Marc from Scalar here,
There's no better feeling than building & being enabled by the software you are integrating with, we've all experienced friction with out-of-date docs, no client SDKs in your favorite language & no one to talk to about your struggles on-boarding.
But we've also experienced those magical APIs that just work and everything you need to reach for is there. This drives our simple three tenants at Scalar: Accessibility, Open-Source, & API First. Making on-boarding easier & magical enables people to build & being API first means your business can scale for the future (LLMs)
Why Open-Source? If done right it builds transparency, builds industry standards (OpenAPI), accelerates innovation & fosters collaboration. We love Open-Source and keep it core to our values.
We are fans of show don't tell here at Scalar: so try our Docs (this page), our SDKs for our API that includes our API Client, Agent Scalar to chat with APIs & our GitHub for all our open-source products. As always, we love your feedback so drop us a line in our discord, email or book a call with me to see how we can help
CEO, Scalar
What are you waiting for?
We're committed to enabling developers and companies to practice the highest of API industry standards.
