Parse, validate, transform, and work with OpenAPI, AsyncAPI, Arazzo, Overlay, and JSON Schema — using one consistent toolchain.
SpecLynx builds parsers, semantic data models, and intelligent editing tools for API specifications — from a low-level semantic parser all the way up to a browser-based editor.
| Product | Description |
|---|---|
| Editor | A browser-based editor for authoring and validating API specifications with real-time feedback. |
| OpenAPI Toolkit | A free VSCode extension for API specification authoring with real-time validation, semantic linting, autocompletion, and live preview. Supports Swagger 2.0, OpenAPI 3.0.x, OpenAPI 3.1.x, AsyncAPI 2.x, and Arazzo 1.x. |
| CLI | A command-line tool for processing API specifications. Ships overlay apply and overlay diff today, with validate, dereference, bundle, and convert on the roadmap. |
| Language Service | An LSP-compatible library that brings API spec intelligence to any editor or tool. 12+ LSP features including validation, completion, hover, go-to-definition, and find references. |
| ApiDOM | A semantic parser that turns any supported API description into a unified data model. Lossless, error-recovery capable, and built on Tree-sitter. |
Teams end up with separate scripts for bundling, linting, converting, and releasing specs — leading to duplicated logic, inconsistent checks, and fragile automation. SpecLynx replaces that with one toolchain:
- One consistent toolchain — the same validation, normalization, and transformation logic across editors, CI pipelines, review workflows, and internal platforms.
- Multi-spec by design — OpenAPI, AsyncAPI, Arazzo, Overlay, and JSON Schema, in JSON or YAML, all through one semantic model.
- Programmable layer — a foundation for developer platforms, documentation systems, governance workflows, and custom specification tooling.
SpecLynx was founded by Vladimir Gorej and Francesco Tumanischvili, two industry veterans with over 15 years of combined experience building and maintaining core tools in the Swagger/OpenAPI ecosystem.
