Nova is an autonomous AI software engineer from Supercode AI, pitched as an open-source alternative to Cognition's Devin . The workflow mirrors what a junior engineer would do on a ticket: it reads the repository, drafts a plan, writes the code, runs the existing test suite, reviews its own diff, and then reports back with what it changed. It targets developers who want an agentic teammate they can actually inspect and self-host rather than a closed hosted product. Nova sits on top of the broader Supercode stack, an open-source AI coding agent that runs in the terminal and can read files, run commands, edit code, open applications, and search the web through natural language, with granular permissions on every action . It is model-agnostic by design, with support for providers including OpenAI, Anthropic, Gemini, DeepSeek, Groq, Mistral, Ollama, and OpenRouter, so teams can route Nova's planning and coding steps to whichever backend they already pay for. The launch matters because the "AI SWE" category is still dominated by closed, credit-metered offerings, and independent teams have been asking for a transparent agent loop they can extend. Supercode is built by Yash Dewasthale (@dewyashtwts), who previously shipped the Supercode beta as an open-source terminal agent , and Nova is the next step from a scoped CLI helper toward an end-to-end coding agent that operates against real repositories.

Been waiting for someone to actually open source this space instead of gatekeeping behind a waitlist. Adding Nova to the weekend tinker list.

The demo cuts right before the tests actually run. Please tell me that wasn't stitched in post.

Every agent demo is pre-recorded. The real test is when it hits a monorepo with 400 circular imports and starts crying.

Tweet copy is fine but burying the repo link in a t.co redirect on a launch day is criminal. Pin the GitHub in the thread.

How's the CONTRIBUTING.md looking? Open source SWE agents live or die by whether I can spin one up in under ten minutes.

Devin alternative is a crowded phrase in 2025. What's the specific thing Nova refuses to do that the others happily fake?

Before I even try it, where does the codebase context get sent and stored? Enterprise legal teams will nuke this on prompt one otherwise.

The landing page kerning on Nova is doing something weird at the O. Otherwise the palette actually looks less AI-slop than most.

Reviews its own work is the part that makes me nervous. Self-graded homework never ends well.

Cool, now ship a GitHub Action so it can actually open PRs on my repos overnight. That's the wedge, not the CLI demo.

One more thing: let me pipe it into Linear so it self-assigns tickets. Then I fire half my roadmap.

Open source SWE agents are a feature, not a company. Curious what the retention story looks like when the base model changes under you.
