Sheet Ninja - Turn Google Sheets into a live CRUD API instantly for vibe coders.

What it does

Sheet Ninja transforms any Google Sheet into a live, RESTful API. Developers can create, read, update, and delete rows in a Google Sheet via HTTP requests, with zero server setup or backend code. The API keys are generated automatically, and the JSON schema mirrors the sheet's header row. Changes made to the sheet are reflected in the API instantly.

Who it is for

Sheet Ninja is designed for "vibe coders"—developers and makers who use AI coding tools like Lovable, Claude, Replit, ChatGPT, Cursor, Bolt.new, and others to rapidly prototype and ship applications. It also suits non-technical founders, marketers, and data scientists who want to build data-driven apps without provisioning a traditional database.

Why it matters

Traditional backend development involves provisioning databases, debugging connection strings, fixing CORS errors, and managing infrastructure—costing hours and monthly fees. Sheet Ninja eliminates this "infrastructure tax" by letting users create a Google Sheet (5 minutes), link it to Sheet Ninja (10 seconds), and start building. This dramatically reduces the time from idea to working prototype, enabling rapid validation and iteration.

Launch signal

Sheet Ninja was featured as a top post on Product Hunt (daily badge) and appeared on Hacker News as a Show HN. The website highlights integration with popular AI coding tools and provides copy-paste prompts for seamless integration. Pricing is transparent: a free Starter tier (250 requests/month), a Pro tier ($9/mo for 10,000 requests), and a Max tier ($49/mo for 750,000 requests).

Brand and naming

The name "Sheet Ninja" combines "Sheet" (Google Sheets) with "Ninja" (skilled, stealthy, efficient), positioning the product as a quick, expert tool for turning spreadsheets into backends. The tagline "Google Sheets as a CRUD Back End for Vibe Coders" clearly communicates the value proposition. The brand voice is playful and direct, using phrases like "Ship vibe-coded apps" and "No StackOverflow at 2am" to resonate with the maker community.
