Developer Utilities Suite — The everyday developer toolbox as one API: UUID generation, QR codes and barcodes, regex testing, JSON validation and diffing, YAML conversion, cron expression explanation, URL and SSL checks, and CSV-to-JSON. Deterministic, fast, no LLM.

⚙️ Rules-based — NOT AI

🚀 Newcomer launch pricing — limited-time introductory rates while we earn our first reviews.

Built for software developers, platform and DevOps engineers, internal-tooling teams.

Why this exists

Every backend re-implements the same small utilities — UUIDs, QR codes, regex checks, JSON and YAML handling — or scatters them across random free websites of unknown reliability.

What you get

One dependable, rate-limited API for the deterministic utilities developers reach for daily, with a single key and one Swagger doc.
