The IDE for parallel agent work. MIT licensed, farm to table, fun. With one click git worktree isolation, first class plan tracking, color coding for agent states, flexible layout arrangement, and so much more, Anvil is crafted to make developers extremely productive, minimizing context switching and maximizing agent parallelism.






Running parallel Claude Codes is a game changer for productivity. We've been using Claude heavily while building Parsli and the bottleneck is always sequential execution. How do you handle context sharing between the parallel instances?
@talal_bazerbachi2 Hi Talal! I typically share context through plan artifacts (markdown files). In Anvil you can actually drag a markdown file from one worktree to another, or have an agent reference those other worktrees.
Is this forked from the VS Code as I am getting kinda similar vibe here. But the feature is really helpful considering running multiple claudes at a time and managing outputs becomes bit overwhelming.
@nayan_surya98 this is built from scratch in rust and typescript! No fork here
Is it possible to work with two or more licenses, for example Claude Code? If the limit on one is reached, can you switch to the second one without losing the project context?
Yo dude, I'm reaching out for a comment.
I’m a researcher for the H1Gallery newsletters (you can google us).
We’re featuring Anvil in our April 3 issue. H1Gallery highlights excellent homepage headlines, and we wanted to reach out to see if you wanted to share a quick comment. The clarity and directness in "The open source IDE for parallel agent work." is very refreshing. The animation is super cool as well. Love it
If you’re up for it, we’d love to get a short note on the copywriting strategy behind your headline and overall messaging. As well as where our readers can follow you on social media, I couldn't find an X account or Linkedin account of yours.
Totally optional to provide a quote for us. The feature is happening regardless, but it’d be great to include your perspective. It makes the newsletter more fun for our readers when we have comments from the creators behind the headlines.
Thanks, really appreciate your time.
How does this compare to what you'd build with something like Docusign or Pandadoc for a team that already has those set up? that's the actual switching cost question and the answer would tell me a lot
Document automation sounds simple, and then it gets incredibly complicated the moment you hit real edge cases. conditional clauses, dynamic tables, and multi party signing flows. Curious how Anvil handles those without the user having to write logic by hand
