Prior monetization attempts like sponsorships and support licenses failed to generate sustainable income. Under the new terms, open source consumers, non-profits, and businesses with annual gross revenue under 1M USD continue under the Apache License 2.0 unchanged. Businesses with revenue at or above 1M USD using these libraries as a direct package dependency in closed-source software must purchase a Six Labors Commercial Use License. Existing commercial license holders keep their terms until renewal. Six Labors is also negotiating with the .NET Foundation to maintain the previous open source license for Foundation projects. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Does upgrading to ImageSharp v3.0.0 require a paid license for my company? Only if your company's annual gross revenue is 1 million USD or more and you use ImageSharp as a direct package dependency in closed-source software. In that case a Six Labors Commercial Use License is required. The license change applies to ImageSharp v3.0.0, ImageSharp.Web v3.0.0, ImageSharp.Drawing v2.0.0, and Fonts v2.0.0; smaller businesses, open source, and non-profit users keep the Apache License 2.0 unchanged. _daily.dev helps teams track licensing changes like this before an upgrade breaks compliance._ ### Will my existing Six Labors commercial license still work after the new split license takes effect? Yes, existing commercial license holders keep their current terms honored until their individual license expiration date, after which renewal is required to keep using Six Labors libraries under the new terms. This applies to products like ImageSharp and ImageSharp.Web moving to the Six Labors Split License. _Developers managing dependency licenses can follow updates like this on daily.dev._ ### Do open source or non-profit users of ImageSharp need to change anything under the new Six Labors license? No, open source, source-available, and non-profit or registered charity consumers continue under the Apache License 2.0 with no changes required, retaining the same freedoms as before. Only closed-source consumers with annual gross revenue of 1M USD or more using the library as a direct dependency are affected by the new Six Labors Commercial Use License requirement. _daily.dev keeps developers informed on license terms affecting the open source libraries they depend on._ ## Similar posts on daily.dev - [Evolving Our License for Long-Term Sustainability](https://daily.dev/posts/evolving-our-license-for-long-term-sustainability-fuz31onib) · Directus · 0 upvotes · 0 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 - [License data quality improvements](https://daily.dev/posts/license-data-quality-improvements-sgomxdbmo) · GitHub Changelog · 1 upvotes · 0 comments - [The new License that protects against tampering with attribution](https://daily.dev/posts/the-new-license-that-protects-against-tampering-with-attribution-8afacsumn) · Medium · 0 upvotes · 0 comments --- Tags: [#open-source](https://daily.dev/tags/open-source), [#.net](https://daily.dev/tags/.net), [#sustainability](https://daily.dev/tags/sustainability), [#licensing](https://daily.dev/tags/licensing) [View this post on daily.dev](https://daily.dev/posts/six-labors-license-changes-for-six-labors-products-dsmwz9xqb) ```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 : License Changes for Six Labors Products","url":"https://daily.dev/posts/six-labors-license-changes-for-six-labors-products-dsmwz9xqb","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/six-labors-license-changes-for-six-labors-products-dsmwz9xqb"},"datePublished":"2026-08-23T12:22:01.136Z","dateModified":"2026-08-23T12:47:20.535Z","description":"Six Labors, maintainers of ImageSharp, ImageSharp.Web, ImageSharp.Drawing, and Fonts, are switching to a new Split License starting with ImageSharp v3.0.0,...","image":"https://media.daily.dev/image/upload/s--VDukGCjf--/f_auto/v1722860399/public/Placeholder%2002","thumbnailUrl":"https://media.daily.dev/image/upload/s--VDukGCjf--/f_auto/v1722860399/public/Placeholder%2002","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-license-changes-for-six-labors-products-dsmwz9xqb","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"open-source,.net,sustainability,licensing","timeRequired":"PT3M"} {"@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 : License Changes for Six Labors Products"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/six-labors-license-changes-for-six-labors-products-dsmwz9xqb#faq","mainEntity":[{"@type":"Question","name":"Does upgrading to ImageSharp v3.0.0 require a paid license for my company?","acceptedAnswer":{"@type":"Answer","text":"Only if your company's annual gross revenue is 1 million USD or more and you use ImageSharp as a direct package dependency in closed-source software.
