How this ranking works
Everything the table draws on continues here: how firm the #1 is, the per-criterion arithmetic behind each score, who pays ChainChoice, and the full guide to choosing.
Direct answer
What is the best block explorers in 2026?
Routescan ranks #1 overall for block explorers on ChainChoice. The operator of snowtrace.io, with a keyless API and a public uptime record at status.routescan.io. It holds that rank under an affiliate-blind methodology scored across 4 published, weighted criteria — the code that ranks providers physically cannot read affiliate payouts (CI-enforced), so a payout can't move a rank. The verdict re-computes on every fee change, incident, or regulatory action; full reasoning and the audit receipt are below.

Each bar is the score on that criterion’s own 0–10 scale, never rescaled to the pool. The dark line is the best any product here reached on that axis. Wt is the most the criterion can add to the 86-point weighted total. Pts is weight × score × 32; the sum is the methodology score, and each weighted point behind the leader costs 2.6 on the displayed score. how these are weighted
Considered and not ranked
4 products we looked at and left out
A shortlist is only honest if it says who it turned away. Each of these was assessed against the same published criteria as the ranked table and excluded for a stated reason — not overlooked.
We assessed 8 products here and rank 4 — 50% of what we looked at. That share is of the products we assessed, not of the category: how many exist is not something we can count, so we do not claim a number for it.

Main tradeoff
status.routescan.io measures availability, not index currency or completeness; it logs a 2h30m maintenance window across all services in mid-August 2026.
Verify before signup
A keyless API call (no key, no account) returned data on 2026-09-14. The published rate limits for keyless and free-key access could not be read: routescan.io returned an access block (CloudFront 403) to the reading client.

What should decide this category
Which chains do you query daily, and are they first-class on this explorer?
Will you depend on the free tier in production, and have you read its rate limits?
Do you need contract verification for your specific toolchain?

Contractual attrition, not downtime, is the measurable record — and it is heavier than the marketing implies. 2026 changelog entries (verified live): Swell deprecated 2026-02-25; Scroll deprecated 2026-04-16; Moonbeam/Moonriver/Moonbase Alpha deprecated 2026-07-31; Gnosisscan explorer discontinued 2026-08-11; and effective 2026-07-01 the free tier's max records per request was cut from 10,000 to 1,000 across ten endpoints while 'Get Internal Transactions by Block Range' moved to Pro. Per the supported-chains page, Gnosis (chain 100) community endpoints require a Lite plan or above as of 2026-09-01. The free tier is marketed as 90% coverage but excludes BNB Chain, Base, OP Mainnet and Avalanche — so for most real multichain workloads the effective entry price is $49/mo, not $0.

Blockscout
The self-hostable multichain challenger — except it stopped being open source on 22 April 2026.
The measurable record is structural and now confirmed against primary sources rather than the announcement blog. Git history shows the LICENSE file carried 'Add GPL3 license' from 2018-02-15 until commit #14201 'chore: Update LICENCE' on 2026-04-22T09:44Z; release v11.0.0 shipped the same day at 16:08Z. The file now reads 'LicenseRef-Blockscout', Version 1.0, Effective Date 2026-04-22 — proprietary/source-available, not GPL. Verified terms: you 'shall not sell, license, monetise, commercialise, or otherwise make available the Software… in exchange for any fee'; you may not distribute Derivative Works to any… The headline differentiator versus Etherscan — 'open source, no lock-in' — stopped being true on 2026-04-22. The licence is now source-available with explicit anti-monetisation, anti-redistribution and forced-branding clauses, and the API is metered with no published overage rate.

mempool.space
Bitcoin's default explorer — AGPL and genuinely self-hostable, now venture-funded and El Salvador-domiciled.
The measurable record is editorial and commercial rather than downtime. October 2024: the project added transaction filtering identifying Ordinals and Runes, drawing sustained public criticism as part of a broader dispute over how Bitcoin services should present non-monetary uses of the chain — a documented case of an explorer operator exercising discretion over what onchain activity it surfaces, which is precisely the neutrality question an institutional buyer must price. July 2024: launched the Mempool Accelerator, a paid transaction-acceleration service routing off-chain fees to partner mining pools, placing… Bitcoin, Lightning and Liquid only — no EVM, no smart contracts, no contract verification — so it cannot serve as a general-purpose explorer and must be paired.
