Alchemy

“Despite offering a wide range of blockchain data APIs across multiple chains, the performance of Alchemy was disappointingly poor, with only 1 out of 12 tests succeeding—indicating significant reliability issues. While the health check was responsive and quick, the overall experience was marred by frequent errors and inconsistent data retrieval, making it hard to trust for production-level applications.”

“Alchemy promises blockchain data at scale across 100+ chains, but it's fundamentally unreliable—only 1 in 12 real-world operations succeeded, which makes it unusable for production systems regardless of how fast the health check responds. The service needs serious stability work before it's trustworthy enough for anything mission-critical.”
