Etherscan Alternative for Custom EVM Chains
Etherscan is the gold standard for browsing Ethereum mainnet. But for your own chain, its EaaS costs six figures, is closed-source, and has a weeks-long setup. Ethernal gives you a fully branded, self-hostable block explorer in under 5 minutes. MIT licensed, from $0.
TL;DR
Etherscan is unmatched for Ethereum mainnet browsing and brand recognition. For custom EVM chains, Ethernal offers a faster, cheaper path: open-source (MIT), self-hostable via Docker, native L2 bridge support, and published pricing starting at $0. Etherscan EaaS requires custom enterprise contracts and is not self-hostable.
Why Teams Look for Etherscan Alternatives
Etherscan is the most recognized block explorer in crypto. For browsing Ethereum mainnet, it is the default. That said, teams launching their own EVM chains run into real friction with Etherscan's Explorer-as-a-Service (EaaS) offering:
- Enterprise pricing. EaaS contracts have been reported at $1-2M/year (CoinTelegraph, Snowtrace incident). There is no public pricing page.
- Closed-source. Etherscan's codebase is proprietary. You cannot audit, fork, or self-host it.
- Weeks-long setup. Deploying an EaaS instance means contacting sales, negotiating contracts, and waiting for provisioning.
- Vendor dependency risk. In 2023, Avalanche's Etherscan-powered explorer (Snowtrace) was discontinued, partly due to high costs. Teams lost their explorer infrastructure overnight.
- API paywalls. In November 2025, Base, Optimism, and Avalanche APIs on Etherscan moved behind $49+/month plans, breaking integrations that relied on free tiers.
None of this changes the fact that Etherscan is the most trusted explorer in crypto. The question is whether that brand justifies six-figure annual costs for your own chain.
Setup and Deployment
Ethernal: Clone the repo, run make start, paste your RPC URL. Under 5 minutes. Or use the hosted version and skip self-hosting entirely.
Etherscan EaaS: Contact sales, negotiate an enterprise contract, wait for provisioning. No self-hosted option. Teams report the process taking weeks.
Bottom line: Ethernal is orders of magnitude faster to deploy. Etherscan EaaS is for teams with enterprise budgets and timelines.
Pricing
Based on published reports (CoinTelegraph, Snowtrace incident)
Ethernal: Pricing is on the website. $0 self-hosted. $0 Starter (hosted, ad-supported). $150/mo Team. $500/mo App Chain (full white-label, 5M transactions). Enterprise on request.
Etherscan is free to browse public chains. API plans range from free to $399/month. EaaS (running your own Etherscan-branded explorer) is custom-priced with no public tiers. Published reports and industry sources cite $1-2M/year for EaaS contracts.
Bottom line: Ethernal's full white-label ($500/month) costs less per year than one month of reported Etherscan EaaS pricing.
Open Source and Data Sovereignty
Ethernal: MIT licensed, full source on GitHub. Self-host on your servers, fork it, change whatever you want. Your data stays where you put it.
Etherscan: Proprietary. No source access, no self-hosting, no way to audit what runs. All data lives on their infrastructure.
Bottom line: If vendor lock-in or data sovereignty matters, Etherscan is not an option. Ethernal and Blockscout are.
Brand Recognition
Etherscan: "Check Etherscan" is a verb at this point. An EaaS instance inherits that trust. For user confidence, that matters.
Ethernal: 370+ chains, 13,000+ users. With full white-label, your users see your brand, not ours. That is the point of white-label.
Bottom line: If Etherscan brand recognition justifies the cost, use their EaaS. If your users should see your brand, white-label is the point.
At-a-Glance Comparison
Who Should Use Etherscan
- Teams where Etherscan brand recognition is worth the enterprise cost
- Projects on chains already supported by Etherscan (Ethereum, BSC, Polygon, etc.)
- Enterprises that want the most established name in block exploration
Who Should Use Ethernal
- Teams launching custom EVM chains who need an explorer now, not in weeks
- Startups and mid-stage teams where $1M+/year for an explorer is not justifiable
- Teams that need full control over their explorer's code and data
- L2/L3 operators who need native bridge monitoring without custom Etherscan integrations
Pricing
Frequently Asked Questions
Is Etherscan free?
Etherscan is free to browse public chains and has free API tiers. Running an Etherscan-branded explorer for your own chain (EaaS) requires an enterprise contract. Published reports cite $1-2M/year. Ethernal is free to self-host and has hosted plans starting at $0.
Can I self-host Etherscan?
No. Etherscan is closed-source and proprietary. Ethernal (MIT license) and Blockscout are the main open-source, self-hostable alternatives for EVM chains.
Does Ethernal have Etherscan-compatible APIs?
Yes. Ethernal provides Etherscan-compatible REST API endpoints. Existing tooling built for the Etherscan API format works with Ethernal out of the box.
What happened with Etherscan and Snowtrace?
In 2023, Avalanche's Etherscan-powered explorer (Snowtrace) was discontinued, partly due to high EaaS costs. This highlighted the vendor lock-in risk of relying on closed-source explorer infrastructure for your chain.
Can I migrate from Etherscan to Ethernal?
If you have your own chain, point Ethernal at the same RPC endpoint. It re-indexes automatically. For public Etherscan-indexed chains, Ethernal connects via your RPC URL independently. No manual data migration is required.
