HN, I\u2019m Kiet \u2013 one half of the two-person team building Onlook (https://beta.onlook.com/), an open-source [https://github.com/onlook-dev/onlook/] visual editor that lets you edit and create React apps live on an infinite canvas.
We launched Onlook [1][2] as a local-first Electron app almost a year ago. Since then, \u201cprompt-to-build\u201d tools have blown up, but none let you design and iterate visually. We fixed that by taking a visual-first, AI-powered approach where you can prompt, style, and directly manipulate elements in your app like in a design tool.
Two months ago, we decided to move away from Electron and rewrite everything for the browser. We wanted to remove the friction of downloading hundreds of MBs and setting up a development environment just to use the app. I wrote more here [3] about how we did it, but here are some learnings from the whole migration:
1. While most of the React UI code can be reused, mapping from Electron\u2019s SPA experience to a Next.js app with routes is non-trivial on the state management side.
2. We were storing most of the data locally as large JSON objects. Moving that to a remote database required major refactoring into tables and more loading states. We didn\u2019t have to think as hard about querying and load time before.
3. Iframes in the browser enforce many more restrictions than Electron webview. Working around this required us to inject code directly into the user project in order to do cross-iframe communication.
4. Keeping API keys secure is much easier on a web application than an Electron app. In Electron, every key we leave on the client can be statically accessed. Hence, we had to proxy any SDK we used that required an API key into a server call. In the web app, we can just keep the keys on the server.
5. Pushing a release bundle in Electron can take 1+ hours. And some users may never update. If we had a bug in the autoupdater itself, certain users could be \u201cstranded\u201d in an old version forever, and we\u2019d have to email them to update. Though this is still better than mobile apps that go through an app store, it\u2019s still very poor DX.
How does Onlook for web work?
We start by connecting to a remote \u201csandbox\u201d [4]. The visual editing component happens through an iframe. We map the HTML element in the iframe to the location in code. Then, when an edit is made, we simulate the change on the iframe and edit the code at the same time. This way, visual changes always feel instant.
While we\u2019re still ironing out the experience, you can already:\n- Select elements and prompt changes
- Update TailwindCSS classes via the styling UI
- Draw in new divs and elements
- Preview on multiple screen sizes
- Edit your code through an in-browser IDE
We want to make it trivial for anyone to create, style, and edit codebases. We\u2019re still porting over functionalities from the desktop app \u2014 layers, fonts, hosting, git, etc. Once that is done, we plan on adding support for back-end functionalities such as auth, database, and API calls.
Special thank you to the 70+ contributors who have helped create the Onlook experience! I think there\u2019s still a lot to be solved for in the design and dev workflow, and I think the tech is almost there.
You can clone the project and run it from our repo (linked to this post) or try it out at https://beta.onlook.com where we\u2019re letting people try it out for free.
I\u2019d love to hear what you think and where we should take it next :)

I made this open source version of Cursor where you can get all of Cursor's core features but in a fully-customizable IDE (ctrl+k, ctrl+L). We love Cursor but there are so many other features we want to build, like allowing AI to edit multiple files at once, or giving AI better understanding of your file system. Void is the open-source, fully customizable tool we've been wanting.
The hard part: we're building Void as a fork of vscode. The repo has great documentation for extensions, but going deeper gets pretty involved. All of the code is OOP-based, and they mount DOM nodes the old-school way (which is what React was supposed to solve..). So adding new UI features isn't exactly trivial. Microsoft also made its extension marketplace closed-source so we (and Cursor) have to hack our way through it. One thing we're excited about is refactoring and creating docs so that it's much easier for anyone to contribute.
The other benefit of open source is we don't need to hide how our prompts are built, so we can transfer the private API logic that Cursor has right onto your local machine. This lets you host a model on-prem and have your data stay completely private. It also means you can go directly to LLM providers (OpenAI, Anthropic) instead of going through us as a middleman.
There's still a lot to build, and full disclosure, we are very early stage. But we're super excited about building and have a working prototype that we're quickly adding features to.
Let us know if there's anything you want to see in a Cursor-style editor. Or feel free to shoot us a pull request.

HN, we\u2019re building mrge (https://www.mrge.io/home), an AI code review platform to help teams merge code faster with fewer bugs. Our early users include Better Auth, Cal.com, and n8n\u2014teams that handle a lot of PRs every day.
Here\u2019s a demo video: https://www.youtube.com/watch?v=pglEoiv0BgY
We (Allis and Paul) are engineers who faced this problem when we worked together at our last startup. Code review quickly became our biggest bottleneck\u2014especially as we started using AI to code more. We had more PRs to review, subtle AI-written bugs slipped through unnoticed, and we (humans) increasingly found ourselves rubber-stamping PRs without deeply understanding the changes.
We\u2019re building mrge to help solve that. Here\u2019s how it works:
1. Connect your GitHub repo via our Github app in two clicks (and optionally download our desktop app). Gitlab support is on the roadmap!
2. AI Review: When you open a PR, our AI reviews your changes directly in an ephemeral and secure container. It has context into not just that PR, but your whole codebase, so it can pick up patterns and leave comments directly on changed lines. Once the review is done, the sandbox is torn down and your code deleted \u2013 we don\u2019t store it for obvious reasons.
3. Human-friendly review workflow: Jump into our web app (it\u2019s like Linear but for PRs). Changes are grouped logically (not alphabetically), with important diffs highlighted, visualized, and ready for faster human review.
The AI reviewer works a bit like Cursor in the sense that it navigates your codebase using the same tools a developer would\u2014like jumping to definitions or grepping through code.
But a big challenge was that, unlike Cursor, mrge doesn\u2019t run in your local IDE or editor. We had to recreate something similar entirely in the cloud.
Whenever you open a PR, mrge clones your repository and checks out your branch in a secure and isolated temporary sandbox. We provision this sandbox with shell access and a Language Server Protocol (LSP) server. The AI reviewer then reviews your code, navigating the codebase exactly as a human reviewer would\u2014using shell commands and common editor features like "go to definition" or "find references". When the review finishes, we immediately tear down the sandbox and delete the code\u2014we don\u2019t want to permanently store it for obvious reasons.
We know cloud-based review isn't for everyone, especially if security or compliance requires local deployments. But a cloud approach lets us run SOTA AI models without local GPU setups, and provide a consistent, single AI review per PR for an entire team.
The platform itself focuses entirely on making human code reviews easier. A big inspiration came from productivity-focused apps like Linear or Superhuman, products that show just how much thoughtful design can impact everyday workflows. We wanted to bring that same feeling into code review.
That\u2019s one reason we built a desktop app. It allowed us to deliver a more polished experience, complete with keyboard shortcuts and a snappy interface.
Beyond performance, the main thing we care about is making it easier for humans to read and understand code. For example, traditional review tools sort changed files alphabetically\u2014which forces reviewers to figure out the order in which they should review changes. In mrge, files are automatically grouped and ordered based on logical connections, letting reviewers immediately jump in.
We think the future of coding isn\u2019t about AI replacing humans\u2014it\u2019s about giving us better tools to quickly understand high-level changes, abstracting more and more of the code itself. As code volume continues to increase, this shift is going to become increasingly important.

Our early users include Better Auth, Cal.com, and n8n\u2014teams that handle a lot of PRs every day.
Here\u2019s a demo video: https://www.youtube.com/watch?v=pglEoiv0BgY
We (Allis and Paul) are engineers who faced this problem when we worked together at our last startup. Code review quickly became our biggest bottleneck\u2014especially as we started using AI to code more. We had more PRs to review, subtle AI-written bugs slipped through unnoticed, and we (humans) increasingly found ourselves rubber-stamping PRs without deeply understanding the changes.
We\u2019re building mrge to help solve that. Here\u2019s how it works:
1. Connect your GitHub repo via our Github app in two clicks (and optionally download our desktop app). Gitlab support is on the roadmap!
2. AI Review: When you open a PR, our AI reviews your changes directly in an ephemeral and secure container. It has context into not just that PR, but your whole codebase, so it can pick up patterns and leave comments directly on changed lines. Once the review is done, the sandbox is torn down and your code deleted \u2013 we don\u2019t store it for obvious reasons.
3. Human-friendly review workflow: Jump into our web app (it\u2019s like Linear but for PRs). Changes are grouped logically (not alphabetically), with important diffs highlighted, visualized, and ready for faster human review.
The AI reviewer works a bit like Cursor in the sense that it navigates your codebase using the same tools a developer would\u2014like jumping to definitions or grepping through code.
But a big challenge was that, unlike Cursor, mrge doesn\u2019t run in your local IDE or editor. We had to recreate something similar entirely in the cloud.
Whenever you open a PR, mrge clones your repository and checks out your branch in a secure and isolated temporary sandbox. We provision this sandbox with shell access and a Language Server Protocol (LSP) server. The AI reviewer then reviews your code, navigating the codebase exactly as a human reviewer would\u2014using shell commands and common editor features like "go to definition" or "find references". When the review finishes, we immediately tear down the sandbox and delete the code\u2014we don\u2019t want to permanently store it for obvious reasons.
We know cloud-based review isn't for everyone, especially if security or compliance requires local deployments. But a cloud approach lets us run SOTA AI models without local GPU setups, and provide a consistent, single AI review per PR for an entire team.
The platform itself focuses entirely on making human code reviews easier. A big inspiration came from productivity-focused apps like Linear or Superhuman, products that show just how much thoughtful design can impact everyday workflows. We wanted to bring that same feeling into code review.
That\u2019s one reason we built a desktop app. It allowed us to deliver a more polished experience, complete with keyboard shortcuts and a snappy interface.
Beyond performance, the main thing we care about is making it easier for humans to read and understand code. For example, traditional review tools sort changed files alphabetically\u2014which forces reviewers to figure out the order in which they should review changes. In mrge, files are automatically grouped and ordered based on logical connections, letting reviewers immediately jump in.
We think the future of coding isn\u2019t about AI replacing humans\u2014it\u2019s about giving us better tools to quickly understand high-level changes, abstracting more and more of the code itself. As code volume continues to increase, this shift is going to become increasingly important.

Here's a quick demo of running it locally: https://www.youtube.com/watch?v=isKhAyivtfM.
At Weave, we write most of our code with AI, and it's been getting more expensive. This came to a head when Opus 4.7 was released and, thanks to its tokenizer changes, our costs shot up. We knew we didn't need Opus for everything but we didn't want to lose out on the intelligence for the cases where you really need it. So we decided to build a model router to handle this for us.
The Weave Router acts as an Anthropic/OpenAI endpoint specifically for coding agents. It looks at every inference request and intelligently (more on that in a sec) decides what model to send it to, handling all the translations required along the way. So it can use faster/cheaper models (e.g. DeepSeek v4, GLM 5.2, Kimi K2.6) when possible, and frontier models (Opus 4.8 & GPT 5.5 (& Fable whenever it's back)) when necessary.
How do we know what model to route to? We trained an RL model on tens of thousands (so far!) of agent traces. We reward the routing model when it selects an LLM that successfully completes the given task.
Here's an example: if you ask the router to plan a complex change, it will (probably) route that request to Opus 4.8. Subagents exploring the codebase to gather context will be routed to more suitable models (e.g. DeepSeek V4 Flash). Then when you have the plan ready to implement, it will be (most likely) be handed to a quicker model (e.g. GLM 5.2) to carry it out.
We've been using this internally for the last month or so. We've saved 40% on tokens vs. what we otherwise would have paid, with no noticeable differences in quality or velocity.
The router is source-available under Elastic License 2.0, so you can self-host it. Or if you prefer, you can also use our hosted version: weaverouter.com.

The main problem: when a UI automation process controls a desktop app today, it usually takes over the human\u2019s session. Your cursor moves, keyboard focus gets stolen, windows jump to the front, and you have to stop working until the agent is done. That is why we have historically avoided encouraging users to run these processes directly on their host machine, instead relying on VMs or GUI containers for concurrency and background execution.
But computer-use - the tools we give agents to operate computers like humans - does not scale cleanly that way. As models get smarter, agents need to share hosts safely, run in the background, and avoid collisions with the human or other agents using the same machine.
We realized macOS has no first-class API for "drive this app without touching the cursor". CGEventPost routes through the hardware input stream, so it moves your cursor. CGEvent.postToPid avoids the cursor warp, but Chromium treats those events as untrusted and silently drops clicks at the renderer boundary. Activating the target app first raises the window and pulls focus, defeating the point of background execution.
Cua Driver is our attempt at a real fix: a background computer-use driver for macOS that lets an agent click, type, scroll, and read native apps while your cursor, frontmost app, and Space stay where they are. The default interface is a CLI, so it is easy to script or call from any coding agent shell.
Try it on macOS 14+:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/trycua/cua/main/libs/cua-d...)"
The first internal use case was delegated demo recording. We ask Claude Code to drive an app while 'cua-driver recording start' captures the trajectory, screenshots, actions, and click markers. The result is an agent-generated product demo, Screen Studio inspired.
Other things we have used it for:
- Replacing Vercel\u2019s agent-browser and other browser-use CLIs. With Claude Code and Cua Driver, you do not need Chrome DevTools Protocol at all.
- A dev-loop QA agent that reproduces a visual bug, edits code, rebuilds, and verifies the UI while my editor stays frontmost.
- Personal-assistant flows that use iMessage from Claude Code, Hermes, or other general-purpose agent CLIs.
- Pulling visual context from Chrome, Figma, Preview, or YouTube windows I am not looking at, without relying on their APIs.
What made this harder than expected:
- CGEventPost warps the cursor because it goes through the HID stream.
- CGEvent.postToPid does not warp the cursor, but Chromium drops it at the renderer IPC boundary.
- Activating the target first raises the window and can drag you across Spaces.
- Electron apps stop keeping useful AX trees alive when windows are occluded without a private remote-aware SPI.
The unlock was SkyLight. SLEventPostToPid is a sibling of the public per-PID call, but it travels through a WindowServer channel Chromium accepts as trusted. Pair it with yabai\u2019s focus-without-raise pattern, plus an off-screen primer click at (-1, -1), and the click lands without the window ever raising.
One thing we learned: the right addressing mode depends on the app. Native macOS apps usually have rich AX trees, Chromium-family apps often need a hybrid of AX and screenshots, and apps like Blender or CAD tools may expose almost no useful AX surface. The mistake is defaulting to pixels everywhere - or defaulting to AX everywhere.
