Welcome to Appear

Instantly document and manage your APIs in real-time.

Welcome to Appear, explicitly crafted for development teams that need to focus on building without being overwhelmed by the complexities of API management.

With Appear, you can instantly access real-time API monitoring and management tools without SDKs, simply with a lightweight drop-in snippet in a single package.

Our platform automatically detects and creates your API documentation and a dynamic, searchable map of your API resources.

Appear's API Catalog explorer experience makes exploring your services intuitive and contextual.

What's Appear's vision?

Appear exists to redefine how APIs are understood, managed, and documented—without adding friction to development.

APIs are the backbone of modern companies and software yet often suffer from poor documentation, fragmented insights, and lack of team visibility. Appear's vision is to eliminate these bottlenecks by making API discoverability, documentation, monitoring, and governance effortless, automated, and universally accessible.

What We Stand For

  • APIs Should Be Self-Describing – Developers shouldn't have to write documentation or guess how an API behaves manually.

  • AI collaboration - AI is a brilliant tool, however, we firmly believe that a human in the loop is crucial to ensure what's created is lasting, impactful, and truly valuable

  • Unified API Management—Teams should have a single source of truth when building, consuming, or governing APIs. Appear does the heavy lifting with integrations to reduce friction into effortless API developer experiences

Where We're Headed

We have lots to do and would love you to join our journey! In the spirit of 'Build in Public', we've exposed our product map to help express our ambition.

Appear aims to be a central hub amongst best-in-class developer tooling to create an ecosystem greater than the sum of its parts.

We're building a platform that not only discovers APIs but also empowers developers, product managers, and architects to move faster with: - Health checks, validation and linting to provide actionable insights for your team - Real-time monitoring and usage insights through integrations with best-in-class tooling - Seamless integration with developer workflows - A foundation for better API compliance for peace of mind - Full lifecycle management with SDKs, and mocks, contract, load, and performance testing

Our mission is simple: Make working with APIs frictionless, so teams can focus on building great software.
