The RISE Project provided RISC-V buildbot machines, and contributors including Ludovic Henry, Furkan Onder, and Emma Smith drove the effort, supported by the Sovereign Tech Agency. Next steps include integrating RISC-V into CPython's CI via RISE's RISC-V Runners initiative, pursuing tier 2 status, and exploring architecture-specific performance optimizations. Users with RISC-V hardware are encouraged to test builds and report issues. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Is RISC-V officially supported by CPython now? Yes, RISC-V is now officially supported by CPython as a tier 3 platform under PEP 11. This follows extended community work including real-hardware testing, architecture-specific bug fixes, and build improvements, with the RISE Project providing dedicated RISC-V buildbot machines for ongoing testing. _daily.dev helps developers porting or testing Python on new architectures track platform support changes like this._ ### What does tier 3 platform support mean for CPython? Tier 3 support in CPython's PEP 11 means a platform has official buildbots that must pass before a release, but failures do not block releases the way tier 1 or tier 2 failures would. RISC-V just reached this status, with plans to eventually pursue tier 2 support and bring RISC-V testing directly into CPython's CI for faster contributor feedback. _developers tracking platform tiers for CPython can follow changes like this through daily.dev._ ### Who supported RISC-V hardware testing for CPython development? The RISE Project supplied several RISC-V machines used as buildbots for CPython testing and architecture-specific debugging. Key contributors included Ludovic Henry from RISE, Furkan Onder, and Emma Smith, with the effort also backed by a Sovereign Tech Agency fellowship supporting the work. _daily.dev keeps developers following open-source infrastructure efforts like RISC-V hardware testing in one place._ ## Similar posts on daily.dev - [CPython Officially Adds RISC-V Support As a Tier 3 Platform](https://daily.dev/posts/cpython-officially-adds-risc-v-support-as-a-tier-3-platform-aj3i412jm) · InfoQ · 0 upvotes · 1 comments - [Announcing the RISE RISC-V Runners: free, native RISC-V CI on GitHub – Rise: RISC-V Software Ecosystem](https://daily.dev/posts/announcing-the-rise-risc-v-runners-free-native-risc-v-ci-on-github-rise-risc-v-software-ecosyst-ig2p7qyvd) · Hacker News · 0 upvotes · 0 comments - [RISC-V 101 – what is it and what does it mean for Canonical?](https://daily.dev/posts/risc-v-101-what-is-it-and-what-does-it-mean-for-canonical--f8lnd00zt) · Ubuntu · 1 upvotes · 0 comments - [The AI Shift: Why RISC-V is poised to challenge Arm and x86](https://daily.dev/posts/the-ai-shift-why-risc-v-is-poised-to-challenge-arm-and-x86-6dds9fta4) · The New Stack · 0 upvotes · 0 comments --- Tags: [#python](https://daily.dev/tags/python), [#open-source](https://daily.dev/tags/open-source), [#architecture](https://daily.dev/tags/architecture), [#cpython](https://daily.dev/tags/cpython) [View this post on daily.dev](https://daily.dev/posts/risc-v-is-now-officially-supported-by-cpython--cyypbssm2) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"RISC-V is now officially supported by CPython!","url":"https://daily.dev/posts/risc-v-is-now-officially-supported-by-cpython--cyypbssm2","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/risc-v-is-now-officially-supported-by-cpython--cyypbssm2"},"datePublished":"2026-08-24T18:59:25.199Z","dateModified":"2026-08-24T18:59:49.741Z","description":"RISC-V is now officially recognized as a tier 3 supported platform for CPython, following months of community work testing on real hardware, fixing...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/6f4659a2a61cdb8b797927fe3798d6be?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/6f4659a2a61cdb8b797927fe3798d6be?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Python Insider","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Python Insider","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/124b62e20f2f41c49bc701276f871a11","url":"https://daily.dev/sources/python"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/risc-v-is-now-officially-supported-by-cpython--cyypbssm2","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"python,open-source,architecture,cpython","timeRequired":"PT3M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Python Insider","item":"https://daily.dev/sources/python"},{"@type":"ListItem","position":3,"name":"RISC-V is now officially supported by CPython!"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/risc-v-is-now-officially-supported-by-cpython--cyypbssm2#faq","mainEntity":[{"@type":"Question","name":"Is RISC-V officially supported by CPython now?","acceptedAnswer":{"@type":"Answer","text":"Yes, RISC-V is now officially supported by CPython as a tier 3 platform under PEP 11.
