Why it ranks first

Why Karnot leads this category right now

Starknet appchains on the Madara sequencer stack, with a published monthly mainnet price. Strongest on a price you can act on before you talk to sales (9/10): Karnot's homepage prices its mainnet tier at "$5000" "/ month" for growing teams, beside a free devnet and testnet tier; the mainnet tier lists automatic upgrades, high uptime, detailed monitoring, on-call support and customisations. It is the only mainnet chain price in fiat on the page where a buyer signs up. Weakest on the documented way out (4/10): Karnot's site carries no key-handover or migration-out statement and no documentation index. What it does state is stack independence: it maintains the open-source Madara framework and tells customers to "Choose your preferred settlement and DA layers." Published price: karnot.xyz (re-fetched 2026-09-25, HTTP 200; karnot.xyz/pricing returns HTTP 404, so the price lives on the homepage), pricing section, quoted exactly. DEVNET AND TESTNETS: "Free" / "For the tinkerers" — "Sequencer Explorer Bridge Faucet Dashboard".

Best for

A price you can act on before you talk to sales — 9/10

Main tradeoff

Karnot is the only vendor that tells you the price before the call — $5,000/month, above the $3,000/month implied by Conduit's own blog — but it is Starknet-only, has exactly one chain L2BEAT tracks, publishes no uptime measurement or status page, and makes no written commitment to hand you the keys. You are buying price transparency and clean on-chain custody on a sample of one, and taking the operating record on faith.

karnot.xyz (re-fetched 25 September 2026, HTTP 200; karnot.xyz/pricing returns HTTP 404, so the price lives on the homepage), pricing section, quoted exactly. DEVNET AND TESTNETS: "Free" / "For the tinkerers" — "Sequencer Explorer Bridge Faucet Dashboard". MAINNET: "$5000" "/ month" / "For growing teams" — "EVERYTHING IN TESTNET, PLUS: Automatic upgrades High uptime Detailed monitoring On call support Customisations". Normalised on 2026-09-25: 5,000 a month x 12 = 60,000 a year in US dollars, all-in for the listed components, with no revenue share attached. The only other vendor-stated mainnet figure in this pool is on a different vendor's blog — conduit.xyz/blog/rollup-total-cost-of-operations-tco (re-fetched 25 September 2026, HTTP 200) still states a cost of thirty-six thousand dollars per year to run a rollup on mainnet plus onchain DA costs, i.e. 3,000 a month — and that figure is contradicted by Conduit's own pricing page, which quotes every mainnet chain tier as Contact for pricing plus five percent of sequencer profit. Karnot's 5,000 a month therefore remains the only mainnet monthly price in this pool published on the page where you would buy it. Both figures were re-fetched on the same day, 25 September 2026, so the comparison is same-date.

Conduit

Managed OP Stack, Arbitrum Orbit and Agglayer CDK chains with RPC and indexing sold separately

Managed OP Stack, Arbitrum Orbit and Agglayer CDK chains with RPC and indexing sold separately. Strongest on the documented way out (9/10): Conduit's FAQ says it will "send the necessary keys to a wallet of your specification as soon as you ask." Its Terms add a 30-day post-termination migration, but only after invoices are paid, onto a new set of sequencer keys, with upgrade keys held by Conduit during the term. Weakest on who can change your chain (2/10): One Safe, "Conduit Multisig 1", clears at 4 of 11 and sits in L2BEAT's admin records for 20 live chains, with 10 upgrade permissions on Zora alone. Conduit's Terms state that a customer chain's upgrade keys are held by Conduit. Ronin shows the alternative: a joint 5-of-6 Safe where Conduit holds a minority.

Alchemy Rollups

OP Stack, Arbitrum Orbit and ZK Stack chains sold alongside Alchemy's node and account-abstraction stack

OP Stack, Arbitrum Orbit and ZK Stack chains sold alongside Alchemy's node and account-abstraction stack. Strongest on independently counted live chains (6/10): L2BEAT credits Alchemy with seven rollups: four live (World Chain, Shape, Settlus, EARNM) and three archived, Degen most recently on 2026-09-02. Alchemy's status page lists components but publishes no uptime percentage against which its "99.99% uptime over 7 years" claim can be tested. Weakest on a price you can act on before you talk to sales (2/10): Alchemy publishes no chain operating price. Its rollups page offers "Deploy for free" and routes everything beyond it to "Schedule a demo"; its docs say costs include deployment fees, monthly subscriptions and usage-based charges without naming a figure. Published price: Chain operating price: not published. alchemy.com/rollups (re-fetched 2026-09-25, HTTP 200) makes "Deploy for free" its primary call to action, with "Schedule a demo" and "Talk to us" for everything beyond it.

Zeeve

Compliance-oriented managed rollups on Arbitrum Orbit, Agglayer CDK and ZK Stack, with certification claims

Compliance-oriented managed rollups on Arbitrum Orbit, Agglayer CDK and ZK Stack, with certification claims. Strongest on who can change your chain (6/10): No Zeeve-named Safe or key holder appears in L2BEAT's records for Zeeve's two live chains, Penchain and Wirex Pay Chain. Its leverage sits at the data layer instead: the Wirex data-availability committee has two members, both on zeeve.online hosts, and needs only one signature. Weakest on a price you can act on before you talk to sales (0/10): Zeeve publishes no rollup price, tier or billing period. The rollups page's only commercial route is "Talk to an expert", its pricing address forwards to a homepage with no rollup price, and its docs index lists no price page. Published price: Not published. zeeve.io/rollups (re-fetched 2026-09-25, HTTP 200) carries no price, tier or plan; the primary commercial affordance is the button "Talk to an expert".

Direct answer

What is the best rollup-as-a-service provider in 2026?

Karnot ranks #1 overall for rollup-as-a-service on ChainChoice. Starknet appchains on the Madara sequencer stack, with a published monthly mainnet price. 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; the full reasoning and the audit receipt are under Methodology.

FAQs

3 questions readers ask before choosing rollup-as-a-service.

Frequently asked

Questions people ask before choosing RaaS

Who actually controls a chain launched through one of these vendors?

Read the upgrade multisig rather than the marketing, because it is public. Across the chains L2BEAT tracks for these vendors, the address able to upgrade the chain is often the vendor's own multisig rather than the team's, and a single Conduit multisig with a four-of-ten threshold appears across twenty-six tracked chains and holds bridge-upgrade rights on eight live ones. That is not necessarily wrong — an early team may genuinely want the vendor operating it — but it should be a decision you made rather than one you discover, and it is why custody carries the heaviest weight here.

Why do so few of these vendors publish a price?

Because the category sells to teams in a procurement cycle rather than to buyers reading a page. Karnot publishes a monthly mainnet figure on its homepage and Conduit publishes a rate card; every other vendor in this pool publishes no chain price at all. One caution the research turned up: a headline deposit figure on one vendor's page is a testnet deposit whose tokens the same page tells you to get free from a faucet, so a number being printed is not the same as a number you can budget against.

How likely is it that my chain outlives the vendor relationship?

Less likely than the category implies. Counting the chains L2BEAT badges to these vendors at a pinned repository commit and recounting them independently gives 44 live against 44 archived — exactly half the fleet is dead. Archived does not always mean failed; testnets and deliberate wind-downs are in there too. But it does mean the base rate for a launched chain still running is around one in two, which is the number to plan a migration path against rather than the vendor's launch count.

Best picks

Best rollup-as-a-service in 2026

Treat the upgrade key as the whole decision, because it is the only part that is an on-chain fact rather than a promise. Across the chains these vendors have launched, the multisig that can change the chain is frequently the vendor's own, and one Conduit multisig alone holds bridge-upgrade rights on eight live chains. Second, ask for a price before you ask for a demo: only Karnot, the smallest vendor here, publishes a mainnet monthly figure, and Conduit publishes a rate card — the rest price by conversation. Third, get the exit in writing. And weigh the operating record honestly: of the chains L2BEAT badges to this category, exactly half are archived, so the question is not whether a vendor can launch a chain but whether the ones it launched are still running.
