The RC introduces a new licensing model: ImageSharp moves to the GNU AGPL v3, with a paid Commercial License available for closed-source use, while existing open-source projects that adopted the library before the license change can continue under Apache 2.0. The same licensing terms extend to ImageSharp.Web 1.0 RC1, ImageSharp.Drawing 1.0-Beta8, and Fonts 1.0-Beta10. The RC is supported for production use, though testing before deployment is recommended, with the final 1.0 expected within a few months. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What license does ImageSharp use as of version 1.0 Release Candidate 1? ImageSharp 1.0 Release Candidate 1 is licensed under the GNU Affero General Public License v3 (AGPL v3), with an alternative paid Commercial License available for closed-source projects and applications. Open source projects that took a dependency on ImageSharp before this license change are permitted to continue using it, including all future versions, under the previous Apache 2.0 License. _Track licensing shifts like ImageSharp's AGPL move on daily.dev before they affect a dependency choice._ ### Can I use ImageSharp 1.0 RC1 in a production application? Yes, ImageSharp 1.0 Release Candidate 1 is supported by Six Labors and can be used in production, though testing the release candidate in an application before deploying is strongly recommended. Any issues found should be filed as a GitHub issue against the ImageSharp repository. The final stable 1.0 release was expected within a few months of the RC1 announcement. _Developers evaluating release candidates for production use follow milestones like this on daily.dev._ ## Similar posts on daily.dev - [SkiaSharp 4.0 is here: announcing the first stable release](https://daily.dev/posts/skiasharp-4-0-is-here-announcing-the-first-stable-release-i6cab6h9v) · .NET Blog · 30 upvotes · 4 comments - [SkiaSharp 4.0 Establishes Milestone-Aligned Release Cadence](https://daily.dev/posts/skiasharp-4-0-establishes-milestone-aligned-release-cadence-cnqoznuu4) · InfoQ · 4 upvotes · 0 comments - [Announcing SkiaSharp 4.0](https://daily.dev/posts/announcing-skiasharp-4-0-1jg4xwdz1) · We Are .NET · 47 upvotes · 0 comments - [Explore What’s New in SkiaSharp 4.0](https://daily.dev/posts/explore-what-s-new-in-skiasharp-4-0-pbe3w4yhs) · Uno Platform · 17 upvotes · 1 comments --- Tags: [#open-source](https://daily.dev/tags/open-source), [#.net](https://daily.dev/tags/.net), [#image-processing](https://daily.dev/tags/image-processing) [View this post on daily.dev](https://daily.dev/posts/six-labors-announcing-imagesharp-1-0-release-candidate-1-cqnttkeoo) ```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":"Six Labors : Announcing ImageSharp 1.0 Release Candidate 1","url":"https://daily.dev/posts/six-labors-announcing-imagesharp-1-0-release-candidate-1-cqnttkeoo","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/six-labors-announcing-imagesharp-1-0-release-candidate-1-cqnttkeoo"},"datePublished":"2026-08-23T12:21:53.900Z","dateModified":"2026-08-23T12:46:11.190Z","description":"Six Labors has released ImageSharp 1.0 Release Candidate 1, a major milestone after 4.5 years of development, focused on performance improvements and bug fixes...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/dd80b7bd8607211a57ccbfc03b564b0e?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/dd80b7bd8607211a57ccbfc03b564b0e?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Six Labors : ImageSharp","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":"Six Labors : ImageSharp","logo":"https://media.daily.dev/image/upload/logos/placeholder.jpg","url":"https://daily.dev/sources/sixlabors"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/six-labors-announcing-imagesharp-1-0-release-candidate-1-cqnttkeoo","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"open-source,.net,image-processing","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Six Labors : ImageSharp","item":"https://daily.dev/sources/sixlabors"},{"@type":"ListItem","position":3,"name":"Six Labors : Announcing ImageSharp 1.0 Release Candidate 1"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/six-labors-announcing-imagesharp-1-0-release-candidate-1-cqnttkeoo#faq","mainEntity":[{"@type":"Question","name":"What license does ImageSharp use as of version 1.0 Release Candidate 1?","acceptedAnswer":{"@type":"Answer","text":"ImageSharp 1.0 Release Candidate 1 is licensed under the GNU Affero General Public License v3 (AGPL v3), with an alternative paid Commercial License available for closed-source projects and applications.
