Key problems Appear solves:
Too many integrations is a death of a thousand cuts.
Rather than spending months integrating each individual tool, streamline your workflow with Appear. Connect with our entire ecosystem today and focus your valuable time on enhancing your product.
Static documentation drifts from reality
Appear passively monitors your private network traffic to generate a live schema, ensuring it consistently reflects actual usage.
By comparing this real-time data with your designed specifications, Appear not only keeps your teams aligned with the current state but also proactively highlights discrepancies and issues, maintaining the integrity of your systems at all times.
Engineers spend too long being blocked
Our philosophy at Appear is simple: let engineers focus on building. By delivering essential API information and insights directly into their work environments, we ensure that developers have everything they need to stay in the zone, boosting productivity and maintaining a seamless workflow.
You're in good company

Begin by integrating Appear’s introspector snippet into your services. Appear will then passively monitor your network traffic, locally deducing the schema without sending any actual content, PII, or sensitive data to our servers—only the structure is reported.
Appear is a SaaS platform that you can start using by simply creating an account. Once set up, you can integrate it with your system and begin accessing all its benefits directly from your browser, CLI, CI environment, or VSCode.
Once you've copied the snippet, simply deploy it in key locations in your system where Appear can detect the most traffic. This may be more than one location, which is perfectly fine.
Read our docs for more information.
Appear helps keep engineers in flow, focusing on problem solving, not information hunting. Engineers can access all of Appear's value through CLI or code editors to keep them where the work happens, instead of in browsers to copy and paste.
Appear is designed to prioritise your data security. Our introspector does identify sensitive data, including PII (Personally Identifiable Information), but it never transfers this data off your system. Instead, we only process and send structural information to our servers. You can audit the introspector code anytime to verify this practice, ensuring a lower barrier to entry and quicker problem-solving.
Once your actual schema is generated or uploaded through your CI process, you can assign ownership and tag services with teams, members, or other relevant categories. This association is readily accessible in CLI and IDEs, helping to maintain workflow continuity for you and your team.
We have plans to support Visual Code and other IDEs in the future. Refer to our Product Map to stay up to date with our progress.
Yes, there is a minimal performance impact due to the processing of request and response bodies, which is inherent in any system analysing real traffic. However, this effect is typically negligible and unlikely to be a concern for most users. Appear uses rate sampling to minimise the amount of data sent from your network, ensuring that performance remains optimised. If necessary, further optimisations, such as processing on a separate thread, can be implemented in the future.
