Five announcements in five days.

You can present marimo notebooks as slides. Widgets stay interactive and you can edit slides live while presenting. No more second window, separate demo, or crossing your fingers.24 Jul 2026 17:13 +0000at://did:plc:vn4czbo4bjg7htko2eh3klsp/app.bsky.feed.post/3mrftyuxp5l24https://bsky.app/profile/marimo.io/post/3mrd5zse6su24marimo is reactive, which means that it knows in what order variables are declared. So what if you had widgets at your disposal that could leverage that? For launch week, we're releasing some tools that do exactly this.23 Jul 2026 15:34 +0000at://did:plc:vn4czbo4bjg7htko2eh3klsp/app.bsky.feed.post/3mrd5zse6su24https://bsky.app/profile/marimo.io/post/3mrasdj5nie2sAsk and you shall receive: marimo now runs natively in PyCharm.
