💡 SaaS Idea: SheetAPI Pro – Secure no-code Google Sheets to REST API

Turns any Google Sheet into a scalable, secure REST/GraphQL API with fine-grained row-level auth, rate-limiting, and caching. Removes OAuth headache and Google quota limits that engineers complain about when prototyping back-ends or internal tools.

Platform: web

Why it's a good idea?

1. Market pain evidence

  • Reddit post supplied by founder (“Tired of the Google Sheets API headache…”) already hit r/node front-page – clear up-votes & comments complaining about OAuth, quotas, and rate limits.
  • Hacker News thread #40016131: people debating whether native Google Sheets API limits (60 writes/min) are usable in production – >120 comments, many looking for alternatives.
  • Google search shows dozens of tutorials titled “Turn Google Sheets into an API” and “Google Sheets as backend” – DIY hacks are popular because official API feels heavy.

2. Search-keyword data (low difficulty, ≥500 searches)

Keyword Monthly volume Difficulty
google sheets database 880 11
google sheets as database 880 1
google sheets api python 880 21
google sheets api 3,600 40 (a bit high)
=> Two core intents (use sheets as DB + use API programmatically) each have 880 searches with single-digit/low-20s difficulty ⇒ plenty of SEO head-room.

3. Competitor landscape & pricing (prove willingness to pay)

  • SheetDB – from $19/mo basic, $129/mo+ for higher tiers.
  • Sheety – freemium, $12–$99/mo.
  • Sheet2API – $9–...
