LynxAPI[04]
[An OpenAPI-first desktop app for API testing, workflows and automation. Specs become collections, requests chain into multi-step flows, and full responses never leave your machine.]

Secure by Default
LynxAPI is designed with privacy-first defaults. We never store your API request or response payloads in the cloud — only non-sensitive response metadata, schemas, and execution statistics are used for analysis. Full API responses remain local to your machine, ensuring your data stays private and under your control at all times.
OpenAPI-Native API Testing
LynxAPI treats OpenAPI as a first-class citizen, automatically converting Swagger/OpenAPI specs into structured collections, requests, and schemas. This ensures your API client always stays in sync with backend changes.
Workflows & User Flows
Create multi-step API workflows that mirror real user journeys. Chain requests together, pass dynamic data between steps, and validate responses to test end-to-end scenarios across environments.
What I did
- Designed and built LynxAPI as a cross-platform desktop application using Tauri, focusing on performance, low memory usage, and native OS integration.
- Implemented a workflow execution engine with environment variable substitution, request chaining, and persistent undo/redo powered by SQLite.
- Developed an AI-assisted API experience, including a chat assistant and agent system for request generation, schema understanding, and workflow automation.
- Architected an OpenAPI diff & sync pipeline to detect added, removed, and updated endpoints when API specs change.
