Rethinking API Design at Scale with the Stoplight Platform

In 2016 Stoplight released the industry’s first form-based OpenAPI designer, and since then we have helped developers, architects, and even product managers design tens of thousands of APIs. Over the last few years, we focused on adding features to take advantage of these OpenAPI documents, such as hosted API documentation and automatic mock servers. However, as we engaged with our customers, we realized that a new set of problems was cropping up as the number of APIs under management grew.

Creating a process to design and develop a handful of APIs at your company is difficult but doable. On the other hand, creating a process to design and develop tens, hundreds, or thousands of APIs at your company, spread across dozens of teams, is a Herculean task. In conversation after conversation, we learned that this is the situation many of our customers find themselves in as development patterns shift toward building and deploying smaller, more specific APIs (microservices).

Managing APIs at this scale introduces a number of new challenges - consistency, governance/compliance, discoverability, and quality become difficult to manage as the number of APIs increases. When we look around at the options for solving these problems, we see a lot of solutions that ask companies and developers to add a completely new workflow to their process. This is a big ask, and one that can stifle attempts at rolling out a more modern API design first program at your company.

What we realized is that most of these problems can be solved in the context of the workflows and tooling that already exist at your company. Your Git repositories are the obvious place to store API design assets. The process you have today to drive code reviews is a great foundation to drive design reviews. The automation you have in place to run test suites is a perfect spot to add API style guide/consistency checks. And so on.

By enriching the tools and workflows that exist at your company today, Stoplight becomes easier to roll out across your entire company, bringing the goal of affecting meaningful improvements to your API development processes one step closer.

🔗 🔗 🔗 🔗 🔗 🔗 The New Stoplight Platform

A primary goal with the Stoplight Platform was to make it as easy as possible to integrate Stoplight into your existing workflows. Stoplight should enrich - not replace - these workflows, thus reducing the friction involved with rolling out a modern API development strategy at your company.

To that end, the Stoplight Platform was built to act as a layer on top of the version control system(s) at your company - GitHub, GitLab, Bitbucket, etc.

This shift yields a number of benefits right off the bat:

1. No lock-in: Your data is your own, stored in your Git repositories.
2. Tooling flexibility: Convincing developers to adopt a new tool can be difficult. With our new approach, developers can continue to use the tools that they’re most comfortable with - all they need to do is commit design/docs files to your Git repos. If some of them prefer to write OpenAPI by hand in VS Code rather than using Stoplight Studio, no problem!
3. Workflow flexibility: Since Stoplight is built on your VCS, it’s easy to leverage the development workflows that already exist at your company - PR reviews, CI, GitHub actions, custom VCS integrations, you name it.
4. Co-locate alongside implementation: In previous versions of Stoplight, you were forced to store your design/docs files in a flat list, separate from the implementation they are meant to describe. In our new Platform you are free to organize your files however you like, including managing them in the same repo as the actual API implementation! This has a number of benefits, such as reviewing changes to design and implementation in a single Pull Request.

🔗 🔗 🔗 🔗 🔗 🔗 What Comes Next

Today we unveiled our vision for the Stoplight product ecosystem - one in which you own your data, and you choose how and when to incrementally layer Stoplight into your existing workflows. Over the next few months we’ll work with customers on our legacy products to help you through the migration process. Please note that you do not have to migrate until you are ready - we are not sunsetting our legacy products at this time, and will provide at least 6 months notice before we do so.

Moving forward we will build on this foundation with shared API style guides, rich design reviews, and more collaboration features. Oh, and Studio desktop is getting an update soon, stay tuned!

You can explore what we’re working on, and make suggestions, on our public roadmap - we look forward to working together.
