About Browse by Technology
Every tool on this platform is tagged with one or more technologies so you can find exactly what you need without scrolling through unrelated categories. Whether you are working with JSON data structures, writing SQL queries, styling with CSS, converting TOML configuration files or testing HTTP APIs, all 189+ tools are cross-referenced by the 28 technologies they cover.

Common Use Cases
- You are working with a JSON API and need formatters, validators, JSONPath querying and TypeScript interface generation all in one place
- You are configuring infrastructure with TOML and need to convert it to YAML, JSON or INI for different toolchains
- You are building an HTTP API and need to test requests, check CORS headers, generate security headers and reference status codes
- You are writing CSS and want Tailwind class generators, Flexbox/Grid visualisers, gradient builders and animation utilities together
- You are designing a GraphQL schema and need a formatter, a JSON-to-GraphQL generator and an OpenAPI explorer
- You are generating client code from a JSON schema and want Go structs, Python dataclasses, Rust enums and Kotlin data classes side by side
Frequently Asked Questions
QHow are tools assigned to a technology?
Each tool is manually tagged with every technology it is directly relevant to. A tool like the JSON-to-YAML converter appears under both JSON and YAML. A CSS gradient generator appears under CSS. Tags reflect actual utility, not loose association.
QAre these tools really free?
Yes — every tool is completely free, with no account, no trial period and no hidden paywall. All processing runs in your browser using WebAssembly and JavaScript.
QDo any tools send my data to a server?
No. All tools process data entirely client-side in your browser. Nothing you paste, type or upload is transmitted to any server.
QHow many technologies are covered?
Currently 28 technologies are covered: JSON, YAML, CSV, XML, SQL, HTML and 22 more. New technologies and tools are added regularly.
QCan I browse by category instead of technology?
Yes — the /tools page organises all tools into functional categories such as Formatters, Converters, Generators, Security, Diagrams and more. Technology browsing complements this by letting you filter across categories by the language or format you are working with.
