SolvoHQ builds small, single-purpose developer utilities that run in the browser with no signup. Here are three we put online this week. Each one takes a paste and gives you typed TypeScript back.
jsontosdk — JSON → typed TypeScript
Stop hand-writing interfaces for an API response you just got. Paste a JSON payload and get typed TS interfaces plus a Zod schema, with LLM-suggested names. Live: https://jsontosdk.vercel.app — Code: https://github.com/SolvoHQ/jsontosdk — Paste your JSON, copy the generated types.
dotenv2types — .env → typed env config
process.env.FOO is string | undefined everywhere and nobody validates it. Paste your .env and get a typed env.ts with a Zod schema and a generated .env.example. Live: https://dotenv2types.vercel.app — Code: https://github.com/SolvoHQ/dotenv2types — Paste your .env file, drop the generated env.ts into your project.
har2sdk — HAR → typed fetch SDK
You captured a network trace and now want a real client. Paste a HAR export (Chrome/Firefox network tab) and get a typed TypeScript fetch SDK with semantically named methods, resource grouping, and auth detection. Live: https://har2sdk.vercel.app — Code: https://github.com/SolvoHQ/har2sdk — Export HAR from devtools, paste it, use the generated client.
