The short version

  • Each has a real cost: Alchemy the free tier is capped at 30M compute units a month and 25 requests per second; Polygonscan the PolygonScan API page now redirects to Etherscan's unified multichain API pricing, so Polygon data is bought under Etherscan plans rather than a PolygonScan-specific one
  • They diverge on capability: Alchemy covers Node APIs, Polygonscan covers Block Explorer.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Alchemy

  • The free tier is capped at 30M compute units a month and 25 requests per second
  • Free accounts are limited to 5 apps and 5 webhooks
  • Beyond the free allowance it is $0.45 per 1M compute units for the first 300M a month
  • Request cost varies by call complexity, from around 10 compute units to over 100, so spend is hard to predict from request counts alone
  • Signed SLAs and priority support require an Enterprise contract

Polygonscan

  • The PolygonScan API page now redirects to Etherscan's unified multichain API pricing, so Polygon data is bought under Etherscan plans rather than a PolygonScan-specific one
  • The free API plan is capped at 3 calls per second and 100,000 calls per day and requires attribution
  • API Pro endpoints start at the Standard plan at $199 per month
  • Rate limits top out at 30 calls per second even on the $899 per month Pro Plus plan
  • Metadata CSV export and dedicated support require Metadata Enterprise, which is quoted by contact with no published price
