Show HN: Vendo (YC S26) – Let your users add their own features to your product
github.com
Me and my co-founder have been thinking a lot lately about how agents are going to change the way that dashboards and UIs are consumed by users. And one of the big things we often come back to is personalization. Everyone has their own workflows, outcomes, and views they want from a product. Instead of devs having to wade through hundreds of feature requests, we think agents will let every user use a product exactly how they want to.
We started working on this problem initially through an open-source software angle: we would let users easily deploy open-source software so they could customize it directly. What we found, though, was that customization alone wasn't enough to convince users to switch to us, and people just wanted to customize what they already use. So we pivoted to what Vendo currently is. We now give businesses the ability to let their users personalize the product directly. Users can generate their own custom micro-apps, customize existing components, create automations, connect to external tools, and more! And the goal is not just to generate UIs, but full-on micro-apps and features that can do real stuff for users.
Everything your users create is built within your existing brand/theming, security guardrails, and API. All the code your users create is run in secure sandboxes, so the application's source code is not touched at all. We have some demo GIFs here if you would like to see how it works: https://github.com/runvendo/vendo
We are open-source (as seen from above) and we can integrate with existing agents (or set up a production-ready one with everything needed) all with one command! That one command lets Vendo learn your brand, components, and API. We currently support Vercel AI SDK but are adding support for other agent frameworks soon.
Please check out the repo, and am happy to discuss how everything works under the hood! Two of the hardest problems we've been working on are (1) generating high-quality and on-brand UIs fast and (2) securing everything while still giving users a lot of power, and would love to share more technical details.
