We're thrilled to announce the initial release of Riff, a Nix-powered CLI tool that automatically provides external dependencies for software projects. Riff supports Rust projects out the gate but we plan to support additional languages in the near future: determinate.systems/posts/introduc…

splits on @replit are out! now you can completely customize the layout of your projects in the workspace. one of the most deceivingly challenging projects ive worked on with Eva. read the blog here: blog.replit.com/splits

We believe that Riff can provide lasting benefits to the Rust Language community. In this post, we make the case that adding Riff metadata to your project—usually just a few lines in Cargo.toml—can go a long way toward addressing an enduring problem in Rust. determinate.systems/posts/riff-rus…

Living up to his moniker, @linux_hackerman describes how he made NixOS's test framework 10x faster with a patch to QEMU: determinate.systems/posts/qemu-fix

Introducing 🌟flox 🌟, a next-generation environment manager built on Nix. We think Nix is the right way to package, build, and share software moving forward, and we leveraged its superpowers to create flox. more 👇🧵

Who wants early access to GPU repls on Replit ⠕? Please only reply if you genuinely think you’re going to use it (and can pay for it).

Introducing the Replit App. We’ve been working on this for over a year inventing new UX paradigms to make coding on mobile manageable, and we think this is the most comprehensive mobile creation tool in the world — will onboard millions to the industry!

Well, this is Expo React Native built with Replit ⠕ 😂

Got a bunch of demos this week on the evolution of our cloud infra and it’s totally insane. Imagine instantly available, fully reproducible, and infinitely scalable environments. Will eat the software market inside out. Not only pro devtools, but going into academia, gov’t etc.

We're building a team to focus on the collaborative multiverse of software. This is a greenfield areas for research in HCI, protocols, systems, social science...etc You can also leverage our infrastructure and ship game changing experiences on day one. jobs.ashbyhq.com/replit/43882c2…

Looking for an insanely fast static site generator, with dark/light mode, pages, search, and code highlighting that requires no configuration just pure markdown files checkout my project mmdoc: ryantm.github.io/mmdoc/

Another important milestone reached today for #tvix ! We now have tooling to (quickly, sub-second) start VMs executing binaries (and closures) from a tvix-store running on the host, passed in via virtiofs, without any need to rebuild initrds. tvix.dev #nix #nixos

AI is incredible at writing code. But that's not enough to create software. You need to set up a dev environment, install packages, configure DB, and, if lucky, deploy. It's time to automate all this. Announcing Replit Agent in early access—available today for subscribers:

Whatever you need… make an app for that. Now on your phone. For everyone. Free.

UI is one of the biggest improvements in the new Replit Agent and Claude 3.7 Sonnet, generally. In this game of Onitama, check out how well designed the cards and tiles are.

You will notice the difference immediately. Better performance, straight to the point. We've been optimizing Replit Agent for Claude Sonnet 4.0 during the past weeks. The upgrade has been rolling out to our users since early this morning -- you will all get it by end of day!

i wrote a blog post on how we built a REPL-based self-testing subagent to go from 20min -> 200 min of autonomous runtime in Agent 3 :) the main thing we wanted to solve was the problem of LLMs generating apps that looked like they worked but were really just high-fidelity mocks

Replit's deep dive into their snapshotting infrastructure, posted Thursday, is worth a read. It highlights a key shift: once agents operate on real application state, experimentation becomes the norm. Agents branch state, explore in parallel, and backtrack frequently.
