It preserves the familiar GNU Radio Companion interface, ships with example flowgraphs, supports common SDRs like the RTL-SDR as well as a computer's sound card as an input source, and includes recorded off-air captures for experimentation. The only noted limitation compared to the desktop version is lack of support for networked SDRs. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Is there a browser-based version of GNU Radio Companion available now? Yes, a browser-based version of GNU Radio Companion has been released by Marc Lichtman, creator of pysdr.org. It replicates the familiar desktop interface, ships with example flowgraphs, supports SDR hardware such as RTL-SDR, works with a sound card as an input source, and includes recorded off-air captures for experimentation. _Developers exploring browser-based SDR workflows can follow tooling shifts like this one on daily.dev._ ### What can't the browser version of GNU Radio Companion do compared to the desktop app? The one confirmed limitation is that it cannot work with a networked SDR, unlike the standalone desktop version of GNU Radio Companion. Otherwise it reportedly supports the same flowgraph building, example projects, RTL-SDR hardware, sound card input, and recorded captures as the original application. _Anyone weighing browser tools against native apps can track these tradeoffs on daily.dev._ ## Similar posts on daily.dev - [GNU Radio Gets A Makeover With PimpMyGRC](https://daily.dev/posts/gnu-radio-gets-a-makeover-with-pimpmygrc-znbzll04r) · Hackaday · 0 upvotes · 0 comments --- Tags: [#hardware](https://daily.dev/tags/hardware), [#webassembly](https://daily.dev/tags/webassembly) [View this post on daily.dev](https://daily.dev/posts/it-s-gnu-radio-companion-but-in-the-browser-s1txnl1bz) ```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":"It’s GNU Radio Companion, But In The Browser","url":"https://daily.dev/posts/it-s-gnu-radio-companion-but-in-the-browser-s1txnl1bz","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/it-s-gnu-radio-companion-but-in-the-browser-s1txnl1bz"},"datePublished":"2026-09-09T15:50:18.050Z","dateModified":"2026-09-13T21:37:43.764Z","description":"GNU Radio Companion, the popular software-defined radio flowgraph tool, now runs directly in the browser via a project called GNU Radio World, built by Marc...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/43d212895051225199552fb0e2b760d9?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/43d212895051225199552fb0e2b760d9?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Hackaday","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":"Hackaday","logo":"https://media.daily.dev/image/upload/s--JhDfhy70--/f_auto,q_auto/v1767541814/logos/hackaday","url":"https://daily.dev/sources/hackaday"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/it-s-gnu-radio-companion-but-in-the-browser-s1txnl1bz","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":1},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"hardware,webassembly","timeRequired":"PT1M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Hackaday","item":"https://daily.dev/sources/hackaday"},{"@type":"ListItem","position":3,"name":"It’s GNU Radio Companion, But In The Browser"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/it-s-gnu-radio-companion-but-in-the-browser-s1txnl1bz#faq","mainEntity":[{"@type":"Question","name":"Is there a browser-based version of GNU Radio Companion available now?","acceptedAnswer":{"@type":"Answer","text":"Yes, a browser-based version of GNU Radio Companion has been released by Marc Lichtman, creator of pysdr.org.
