We compared six Etherscan alternatives on features, fees and supported chains, and noted where each one falls short of Etherscan.
No project pays to be listed. How we rank
The closest Etherscan alternative is Blockscout: its free PRO API allows 5 requests per second across 100+ chains, against Etherscan's 3 calls per second on 60+ chains. Below are six Etherscan alternatives and competitors, from other block explorers to SQL analytics and debugging tools, compared on API limits, chain coverage and price.
Etherscan is a block explorer for Ethereum, launched in August 2015 by Matthew Tan. Its API V2 serves 60+ chains with one key: the free tier allows 3 calls per second and up to 100,000 calls a day on selected chains, and paid plans start at $49 a month. See the full Etherscan profile →
The free tier allows 3 calls per second and 100,000 calls a day, but only on selected chains and with attribution. If you need other chains for free, compare limits elsewhere.
API Pro endpoints start at the Standard plan, $199 a month. The entry Lite plan is $49 a month.
Robinhood Chain and Arc endpoints move behind the $49 Lite plan on October 16, 2026. If your app reads those chains, plan for the cost or a second provider.
| Name | Best for | Chains | Chains |
|---|---|---|---|
| Etherscan ORIGINAL | Baseline | Ethereum, plus 60+ chains through the API | 60+ chains via API V2 |
| Blockscout | EVM explorer and API | EVM chains | EVM chains; PRO API covers 100+ chains |
| OKLink | Bitcoin, TRON and EVM | Not verified | Bitcoin, Ethereum, TRON, Solana, BNB Chain, Polygon, Base, Arbitrum, Optimism, Sui, X Layer and others |
| Ethplorer | Token portfolios on Ethereum | Not verified | Ethereum mainnet; Sepolia and Hoodi testnets |
| Dune | Onchain SQL and dashboards | Not verified | 130+ chains |
| Tenderly | Simulating and debugging txs | EVM networks | 100+ networks |
| Bitquery | GraphQL across 40+ chains | Not verified | 40+ chains; 10 core chains on self-service plans |
“Not verified” means we have not yet checked the value against the project’s own documentation.
A block explorer for EVM chains that projects can self-host or buy hosted. Its free PRO API allows 5 RPS and 100K credits a day across 100+ chains. Limitation: a default call costs 20 credits, so the free tier is about 5,000 calls a day.
A multichain explorer whose list includes Bitcoin, Ethereum, TRON, Solana, BNB Chain, Base, Arbitrum and Sui, plus a CEX assets dashboard. Limitation: API rate limits and prices are not published in its docs.
An Ethereum explorer built around ERC-20 tokens, with address portfolios, historical USD balances and CSV export. Limitation: Ethereum mainnet only, and the free API allows 1,000 requests a day with 30 days of history.
Instead of browsing one address at a time, you write SQL against decoded blockchain tables and publish dashboards; its homepage lists 130+ chains. Limitation: free access after the trial is view-only, with no API exports.
A developer platform for simulating, debugging and monitoring transactions across 100+ networks. Limitation: the free plan excludes Node RPC, and RPC capacity is set through sales rather than a public price list.
A data provider with GraphQL APIs and WebSocket streams for 40+ chains, including DEX trades. Paid plans start at $39 a month billed annually. Limitation: free access is a 7-day trial, and archive history costs from $70 a month per chain.
For a free API with more chains: Blockscout. For Bitcoin and TRON in one explorer: OKLink. For SQL analysis: Dune. For debugging transactions: Tenderly.
If you mostly use Etherscan's API, Blockscout is the closest swap: a free PRO API at 5 requests per second across 100+ chains, with paid plans also from $49 a month. If you need Bitcoin or TRON next to EVM chains, OKLink covers them in one explorer, though its API limits are not published.
For work that goes beyond looking up one transaction, pick by job: Dune for SQL across 130+ chains, Tenderly for simulation and debugging, Ethplorer for ERC-20 portfolios on Ethereum mainnet.

Blockscout. Its free PRO API allows 5 requests per second and 100K credits a day across 100+ chains, against Etherscan's 3 calls per second on selected chains.
Partly. The free tier allows 3 calls per second and up to 100,000 calls a day on selected chains, with attribution. Paid plans start at $49 a month, and Pro endpoints at $199.
OKLink. Its explorer list includes Bitcoin, TRON, Solana and EVM chains such as Ethereum, Base and Arbitrum.
Ethplorer shows address portfolios with historical USD balances and exports history to CSV. It covers Ethereum mainnet only.
Since August 2015. It was founded by Matthew Tan.
