The program provides complimentary Claude Max 20x access for six months. The team plans to use it to accelerate framework iteration, improve developer experience, and make ExpressoTS more token-efficient for AI-assisted development workflows. ## Content Big news for us. ☕ Fresh off crossing 500k+ downloads a week on npm, we've got more to celebrate: our core maintainer has been accepted into the Claude for Open Source Program by [**Anthropic**](https://www.linkedin.com/company/anthropicresearch/). The program recognizes open-source maintainers with complimentary access to Claude Max 20x for six months, and we will be putting his to work directly on ExpressoTS. Here's where it goes: → Faster iteration on the framework, CLI, and ExpressoTS Studio → More time on developer experience, less on boilerplate → Making ExpressoTS more token-efficient for AI-assisted development, so building with an LLM in the loop costs fewer tokens and just works Programs that back the people maintaining open source are a real signal that the work matters. Thank you to the team behind the Claude for Open Source Program for supporting the maintainers who keep the ecosystem running. ## Similar posts on daily.dev - [Claude Code can now be modded like a video game, and I couldn't stop tinkering](https://daily.dev/posts/claude-code-can-now-be-modded-like-a-video-game-and-i-couldn-t-stop-tinkering-dzon9seci) · XDA Developers · 1 upvotes · 1 comments - [Anthropic Accidentally Exposes Claude Code Source via npm Source Map File](https://daily.dev/posts/anthropic-accidentally-exposes-claude-code-source-via-npm-source-map-file-q8zndwfb4) · InfoQ · 0 upvotes · 0 comments --- Tags: [#ai-coding](https://daily.dev/tags/ai-coding), [#anthropic](https://daily.dev/tags/anthropic), [#claude](https://daily.dev/tags/claude), [#open-source](https://daily.dev/tags/open-source) [View this post on daily.dev](https://daily.dev/posts/claude-for-open-source---we-are-in--dnrfftxuh) ```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":"DiscussionForumPosting","mainEntityOfPage":"https://daily.dev/posts/claude-for-open-source---we-are-in--dnrfftxuh","headline":"Claude for Open Source - We are in!","text":"ExpressoTS, a TypeScript framework with 500k+ weekly npm downloads, announces its core maintainer has been accepted into Anthropic's Claude for Open Source Program.
