JSight provides a concise, human‑readable language for defining both REST and JSON‑RPC APIs in a single file, with automatic conversion to OpenAPI and responsive HTML documentation. Its open‑source validator library and multi‑language bindings enable real‑time traffic validation and CI/CD integration, while a cloud‑based editor supports collaborative design and versioned sharing. The platform streamlines API design, documentation, and testing for backend developers and DevOps teams.

Problem
Designing and maintaining API specifications often involves verbose formats like OpenAPI, which can be difficult to read and error‑prone. Teams frequently struggle to keep documentation synchronized with implementation, especially when supporting both REST and JSON‑RPC endpoints. Manual validation of request/response payloads adds additional overhead and risk of runtime failures.
Solution
JSight introduces a concise, human‑friendly API definition language that reduces syntactic noise while supporting both REST and JSON‑RPC in a single file. The platform offers a web‑based editor for collaborative design, a command‑line interface for CI/CD integration, and a validator library that checks HTTP traffic against the spec in real time. Built‑in converters generate OpenAPI definitions and polished HTML documentation automatically, eliminating manual translation steps. Multi‑language validator bindings (Java, Go, PHP, etc.) enable seamless embedding into existing services. All tools are open source and free, allowing teams to adopt the workflow without licensing constraints. Cloud sharing features let stakeholders review and comment on specifications directly from the browser. The overall stack accelerates API design, improves consistency, and reduces runtime errors.
Target Audience
The primary users are backend developers, API architects, and DevOps engineers who design, document, and test microservice interfaces, as well as product teams that need reliable, up‑to‑date API specifications for internal and external consumption.
