Why this rank
Why Starknet Foundry (snforge) ranks #3
Each strength is read from evidence on a 0–10 ladder and weighted as the published methodology states. The 32 objective points these produce (24.5 here) sit inside the score; availability, friction, trust record and measured data add the rest.

What would move the rank
Each line is the ranking run again with one of Starknet Foundry (snforge)’s criterion scores changed and every other value held: the smallest whole-point change on that criterion that moves its rank, and where the re-run puts it. Up to 4 climbs and 3 falls are listed, smallest change first. Nothing here is a forecast.

Record watch-outs
- Three scoring calls a reader should be able to overturn. FIRST, maintenance scores 9, not 8, because of a twice-weekly nightly channel published to a different repository (software-mansion-labs/starknet-foundry-nightlies), whose newest artifact nightly-2026-08-12 shipped on the day of the check. This category's scoring guide names snforge v0.63.0 (2026-08-06) as its 7-8 example, so a reader who follows that example over the numeric floor lands at 8; the measurements are the same either way and are all in the evidence, and the 9 stands because the example was set from the releases tab alone. SECOND, supply chain scores 5, not 6: verification is worse than absent. Offsetting that, there is a pinning path (scripts/snfoundryup -v/--version/-c), so a reader who weights pinning over verification can defend 6. THIRD, coverage and gas profiling are counted native because --coverage and --build-profile are snforge's own flags, but both shell out to separately installed binaries (cairo-coverage and cairo-profiler, same maintainer, both MIT and active); a stricter count lands on 3 native and a lower band. Nothing is scored on Starknet's merits, Software Mansion's reputation, or stars and downloads; fork tests against an RPC endpoint are left to RPC Nodes, and starknet-devnet is credited only as an integration. The missing invariant or stateful testing engine, searched for under five distinct terms, is the largest functional gap against EVM Foundry and is why testing depth is 9 and not 10.

Facts
facts, not scoresWhat the record publishes
- Pricing
- No pricing is published, because nothing is sold: Starknet Foundry publishes no pricing page, no plan table and no paid tier anywhere in its single-page docs build (https://
foundry-rs .github .io /starknet-foundry /print .html, 646,490 bytes, fetched 28 September 2026). The string "pricing" appears zero times, as do "per month", "subscription", "enterprise", "paid plan" and "free tier"; every "price" occurrence is a gas-price CLI flag or its help text ("Maximum L1 gas unit price ..."), a sample `Product { name, price }` struct in a testing example, or the fee to deploy an account — none is product pricing. The repository LICENSE (https:// github .com /foundry-rs /starknet-foundry /blob /master /LICENSE, HTTP 200, re-fetched 28 September 2026) reads "The MIT License (MIT)" / "Copyright (c) 2023 Software Mansion <swmansion.com>" / "Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction". The registry entry at scarbs.xyz/packages/snforge_std (snforge_std 0.64.0) lists "License non-standard" — a registry classification, not a second licence document; the repository LICENSE is MIT. Cost to a buyer is zero in licence fees; the real costs are the RPC endpoint fork tests call (out of scope here — rpc_nodes) and engineering time.Starknet Foundry (snforge) — official pricing page ↗ · 28 September 2026 - Prices published in

- 10 October 2026
2026.10.8When nothing serves your country, the list shown for reference is the published ranking · platform-wide- fixed The reference list shown when nothing serves your country is the published order with the published scores, and a build check now fails any such list out of that order or with a score the ranking does not publish.
- fixed The explorer prints an overall rank only for a row the published ranking holds; a country entrant such as Coinbase Commerce for US merchants shows no overall rank.
- changed Published orders do not move. Country results change only where nothing serves the country: in India bill pay keeps Bitcoin Well first and now shows Strike second, as published; 35 such runs across all categories and countries now match the published list exactly.
- 10 October 2026
2026.10.6A criterion you require re-scores the rows that meet it · platform-wide- changed The explorer sends each criterion you require, at any band, as fit_required with your other answers; region, licence, chain and fact filters stay filters. On /best, a required criterion joins For you as a marked preference does, which needs your country; Overall stays the published ranking, filtered.
- added Every published criterion has a golden case as the explorer sends it (require:<criterion>), so the order a requirement gives is replayed and gated as the published order is, and a change to it needs an entry here.
- 16 September 2026
2026.09.15Dimension scores carry tenths, and eleven more categories are re-read from primary sources · platform-wide- changed Dimension scores resolve to tenths of a point (O-04b), and weightedTotal is rounded to six decimal places before the order is read. 518 published scores move across 107 categories that were not re-read; none of them moves by more than 4 points, and most move by 1.
- fixed 66 published scores change in the eleven re-read categories, against a verbatim source each. The largest moves are Reflexer RAI (−16), Beefy and Unrekt (−11), Aztec (−10) and Golem (+9) — all of them rows whose sources had moved since their last read.
- changed Published order moves in 38 of 119 categories and three #1s change: smart_contract_audits (Zellic → Certora) and travel_rule_compliance (Sumsub Travel Rule → CodeVASP) on the finer resolution, kyc_compliance (Veriff → Sumsub) on the re-read.
- added availabilitySource (O-04g): for a reader who states a country, a row whose availability in that country rests on a region tag its record gives no source for sorts below every sourced row. It is inert in every order published here, which states no country.
