We compared five Arbiscan alternatives on features, fees and supported chains, and noted where each one falls short of Arbiscan.
No project pays to be listed. How we rank
Arbiscan is the Arbitrum block explorer built by the Etherscan team; other Arbitrum explorers include Blockscout (arbitrum.blockscout.com), OKLink and Tenderly. Below are five Arbiscan alternatives compared on free API limits, chain coverage, price and what each does beyond a plain explorer.
Arbiscan is a block explorer for Arbitrum One and Arbitrum Sepolia, built by Team Etherscan. It shows L1 to L2 and L2 to L1 transactions and batches. Its API is the Etherscan multichain API: free at 3 calls per second and 100,000 calls a day, with paid plans from $49 a month. See the full Arbiscan profile →
The free tier allows 3 calls per second and 100,000 calls a day, but requires attribution and covers selected chains only.
API Pro endpoints start at $199 a month. The cheapest paid plan, Lite, is $49 a month.
Arbiscan covers Arbitrum One and Arbitrum Sepolia. If you follow funds across several chains, a multichain explorer saves switching sites.
| Name | Best for | Chains | Chains |
|---|---|---|---|
| Arbiscan ORIGINAL | Baseline | Arbitrum One | Arbitrum One, Arbitrum Sepolia |
| Blockscout | Arbitrum explorer plus API | EVM chains | EVM chains; PRO API covers 100+ chains |
| OKLink | Arbitrum plus BTC and TRON | Not verified | Bitcoin, Ethereum, TRON, Solana, BNB Chain, Polygon, Base, Arbitrum, Optimism, Sui, X Layer and others |
| Etherscan | Ethereum side of bridges | Ethereum, plus 60+ chains through the API | 60+ chains via API V2 |
| Tenderly | Simulating Arbitrum txs | EVM networks | 100+ networks |
| Birdeye | Arbitrum token prices | Solana, Ethereum, BNB Chain, Base and other EVM and non-EVM networks | Solana, Ethereum, BNB Smart Chain, Base, Sui, Aptos, Arbitrum, Polygon and more (17 listed) |
“Not verified” means we have not yet checked the value against the project’s own documentation.
Runs its own Arbitrum One explorer at arbitrum.blockscout.com, and 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 Arbitrum next to Bitcoin, Ethereum, TRON, Solana, Base and Sui, so you can follow funds across chains on one site. Limitation: API rate limits and prices are not published in its docs.
Arbiscan's sister explorer for Ethereum mainnet, where the L1 side of Arbitrum deposits and withdrawals settles. One API V2 key covers 60+ chains. Limitation: the free tier covers selected chains only and needs attribution.
A developer platform for simulating, debugging and monitoring transactions; its supported networks list includes Arbitrum among 100+ networks. Limitation: the free plan excludes Node RPC, and RPC capacity is set through sales.
A market data tool for token prices, charts, trades and wallets; its API docs list Arbitrum among 17 networks. Paid API plans start at $39 a month. Limitation: the free API tier is limited to 1 request per second.
For a free Arbitrum API with higher limits: Blockscout. For Arbitrum plus Bitcoin and TRON: OKLink. For debugging Arbitrum transactions: Tenderly.
For looking up Arbitrum transactions and calling an API, Blockscout is the closest swap: it runs its own Arbitrum One explorer and its free PRO API allows 5 requests per second against Arbiscan's 3. If you trace funds that leave Arbitrum for Bitcoin or TRON, OKLink puts those chains in one explorer.
Developers who need to replay or simulate a failed Arbitrum transaction should add Tenderly, and the L1 side of bridge transfers is easiest to read on Etherscan, which shares Arbiscan's API key.

Blockscout. It runs an Arbitrum One explorer at arbitrum.blockscout.com and its free PRO API allows 5 requests per second, against 3 on Arbiscan's free tier.
Team Etherscan. Arbiscan uses the Etherscan multichain API, so one key works across Etherscan's 60+ chains.
There is a free tier: 3 calls per second and up to 100,000 calls a day, with attribution. Paid plans start at $49 a month, and Pro endpoints at $199.
Arbitrum One and the Arbitrum Sepolia testnet. It also shows L1 to L2 and L2 to L1 messages and batches.
Yes, with Tenderly. Its supported networks include Arbitrum, and full simulations over its Node RPC cost 400 TU each.
