Strengths
- Largest free public RPC catalog by chain count.
- Single rpc.ankr.com URL pattern across networks keeps integration code small.
- Cosmos SDK chain coverage is unusually broad for an EVM specialist.
Considerations
- Public endpoints are best for development and read traffic, not production write loads.
- Premium tier rate limits should be sized to peak burst, not steady state.
