Getting reliable financial indicators shouldn't be this hard.
“Alpha Vantage cut their free tier to 25 calls/day”
Most free APIs are too restrictive for real development and testing workflows.
“Twelve Data starts at $79/mo — too expensive for side projects”
Premium pricing locks out indie developers and small teams who need reliable data.
“GOOGLEFINANCE() has zero technical indicators”
Spreadsheet users are stuck with basic price data — no RSI, MACD, or Bollinger Bands.
“Calculating indicators from raw OHLCV? Error-prone and tedious”
Building your own indicator library means debugging math, managing edge cases, and maintaining code you didn't want to write.
There's a better way. indictr is the affordable, developer-friendly alternative.
