SolvoHQ builds small, single-purpose web tools for developers. No login, no install, no account — paste in, copy out. Here are three we put online this week. Each one is open source and runs the same way: paste your input, get typed TypeScript back in a few seconds.
jsontosdk — JSON sample to a typed TypeScript SDK
Hand-writing TypeScript types from a sample API response takes 5–30 minutes per endpoint, and most small or internal APIs never publish an OpenAPI spec to generate from.
Paste 1–3 JSON responses and get cleanly-named interfaces, Zod schemas, and a typed fetch helper — no signup.
dotenv2types — .env to a typed env module
Validating environment variables means hand-writing a Zod or envalid schema that mirrors your .env and keeping the two in sync by hand.
Paste a .env and get a typed env.ts with a Zod schema plus a commented .env.example — no signup.
har2sdk — HAR capture to a typed fetch SDK
Turning a browser network capture into a typed client normally means a two-step HAR to OpenAPI to TypeScript detour.
- Live: https://har2sdk.vercel.app
- Source: https://github.com/SolvoHQ/har2sdk
Paste a HAR file exported from Chrome or Firefox DevTools and get a typed TypeScript fetch SDK with semantic method names, resource grouping, and auth detection — no signup.
All three are open source under the SolvoHQ org. Feedback welcome — open an issue at https://github.com/SolvoHQ/jsontosdk/issues.
