Windsurf – Agentic IDE
At Codeium, we've been building AI-powered extensions for a while (we first launched our VSCode extension with autocomplete a little over 2 years ago!), but we've always thought there would come a day where we would hit the limits of what could be achieved within existing IDEs, so we decided to build our own: Windsurf (yes, it's yet another VSCode fork :) We've stuffed a lot of cool features into Windsurf—a super fast autocomplete model, an inline diff generation experience that feels truly native, but we're most proud of Cascade, which is an evolution of the sidebar chat experience that…
Windsurf – Agentic IDE launched on November 13, 2024 with 101 votes, #423 of 4,990 launches that month and more than 90% of that year's launches. The site was not reachable when checked in September 2026.
In plain words
Windsurf is an AI-powered IDE built by Codeium as a VSCode fork. It features fast autocomplete, native inline diff generation, and Cascade, an agentic chat tool that reasons about codebases, runs terminal commands, and tracks user actions. The IDE is designed for developers who want AI assistance integrated directly into their coding environment with deep code understanding capabilities.

Notte Browser Agents2025 · notte.cc · ▲275Hey HN, We’ve been building browser agents for a while. In production, we kept converging on the same pattern: deterministic scripts for the happy path, agents only for edge cases. So we built Demonstrate Mode. The idea is simple: You perform your workflow once in a remote browser. Notte records the interactions and generates deterministic automation code. How it works: - Record clicks, inputs, navigations in a cloud browser - Compile them into deterministic code (no LLM at runtime) - Run and deploy on managed browser infrastructure Closest analog is Playwright codegen but: - Infrastructure…

I'm Varun, CEO of Exafunction, and we just released Codeium to open up access of generative AI to all developers for free. In the spirit of Show HN, we created a playground version for anyone to try this tech in the browser (click Try in Browser)! We have built scalable, low-latency ML infra for many top AI companies in the past, and we are excited to leverage that tech into a product that we, as developers, would love. We hope that you do too, and we would appreciate any feedback that this community has for us!
Basin MCP2025 · mcp.basin.ai · ▲168tl;dr - try Basin AI with Cursor/Windsurf, instruction here (https://mcp.basin.ai), and use API key hackernews to gain access. Hey HN — I’m Henry, co-founder of Basin, and I wanted to share something we’ve been working on called Basin MCP, a kind of QA infrastructure for AI coding copilots like Cursor, Windsurf, etc. We built Basin because we kept noticing the same thing: agentic coding tools are great at generating code, but have no idea if the thing they built actually works — or even matches the original intent, and so they're prong to hallucinations. Basically, they have…
- FLFree local security checks for AI coding in VSCode, Cursor and Windsurf2025 · ▲43
Hi HN! We just launched Codacy Guardrails, an IDE extension with a CLI for code analysis and MCP server that enforces security & quality rules on AI-generated code in real-time. It hooks into AI coding assistants (like VS Code Agent Mode, Cursor, Windsurf), silently scanning and fixing AI-suggested code that has vulnerabilities or violates your coding standards, while the code it’s being generated. We built this because coding agents can be a double-edged sword. They do boost productivity, but can easily introduce insecure or non-compliant code. One recent research team at NYU found that 40%…

Lovable▲1,477Hey HN! Previous CERN physicist turned hacker here. We've developed a way to make AI coding actually work by systematically identifying and fixing places where LLMs typically fail in full-stack development. Today we're launching as Lovable (previously gptengineer.app) since it's such a big change. The problem? AI writing code typically make small mistakes and then get stuck. Those who tried know the frustration. We fixed most of this by mapping out where LLMs fail in full-stack dev and engineering around those pitfalls with prompt chains. Thanks to this, in all comparisons I found with: v0,…

I wasn't quite sure if this qualified as "Show HN" given you can't really download it and try it out. However, dang said[0]: > If it's hardware or something that's not so easy to try out over the internet, find a different way to show how it actually works—a video, for example, or a detailed post with photos. Hopefully I did that? Additionally, I've put code and a detailed guide for the netboot computer management setup on GitHub: https://github.com/kentonv/lanparty Anyway, if this shouldn't have been Show HN, I apologize!
