Solid - AI that builds real web apps
by•
Unlike Lovable and other prototyping tools, Solid builds real full-stack web apps (Node.js, React, TypeScript). Production-grade code you can scale, maintain, migrate and extend. Don’t waste time on AI builders that only build limited prototypes. Start right.

Sometimes the simplest ideas end up being the strongest.

@vincent_chen11 😍
Pretty impressive—at least from a UI point of view. Solid also managed to draw inspiration from the UI components I fed to it which is a big upside for me. I just wish there were more free credits, as I ran out of mine when trying to create the second project.
Solid
@maxim_bortnikov Appreciate that! 🙌 Glad the UI + custom components worked well for you. And totally hear you on credits, you have 30 free credits per day =)
Tried it and was honestly surprised by how legit the output is, clean React + Node.js code, not some throwaway prototype. This feels like the first AI builder I’d actually use for a serious MVP.

Your block portfolio on the site contains some very cool projects from a design point of view.
Congratulations on the launch!
I don't think it's a great idea to diss Lovable and the others. Especially since your UI looks like it was ripped right off from there. Anyway - it might be a useful tool - i tried it out, but apparently ran out of credits.
@mananpandya Totally fair point. We’re not here to “diss” Lovable, Bolt, or anyone else. In fact, they’ve done a great job proving how fast AI can get you from idea to prototype.
Where we see the gap is in what happens after the demo stage.
Lovable & Bolt: great for quick prototypes, but they rely on pre-built/managed backends (e.g. Supabase, proprietary infra). That’s fine early on, but once you need to scale, customize deeply, or migrate, you hit friction.
Solid: we generate real React, Node.js, Postgres codebases that you fully own. No lock-in, no black boxes. You can extend, host or scale however you want, the same way an experienced dev team would build it.
So in short, others are awesome for MVP demos. Solid is built for builders who want to go from MVP to production without rebuilding everything from scratch.
@mananpandya how is proprietary infra bad for scale?

Read it from base44 users: “No it just downloads the frontend, the backend is native to Base44. Don't get me wrong, base44 is an amazing tool, especially because it is so simple, but that simplicity comes from a tight coupled, boxed system. If you want to build something to later further develop on your own, use something else.” https://www.reddit.com/r/Base44/comments/1n06t6q/how_to_migrate_away_from_base44/?share_id=tR_H6ZXAx2ACbZY-0RhQb&utm_content=1&utm_medium=ios_app&utm_name=ioscss&utm_source=share&utm_term=3
Or lovable users: “reality, I’ve never seen anyone ship a fully functional app with it. What you usually end up with is just a thin MVP.”

@michael_vavilov I'm guessing, that was for Kumar. I'd agree with the makers on this though. At the early stages, proprietary infra is good - but scaling costs can make a big impact. Most of them are built on top of AWS / similar so of course they add up markup to the base costs - which can be as little as 10% or as much as 100%. You would want control there so a +1 for Solid from me here.
@zerotox I totally get you. But a lot of vibe coders (me included) have worked with Lovable so portraying us as "toy makers" may not be a good spin. Just saying. The product sure looks good. I just disagree on the marketing spin personally :-) Good luck with the launch!
@mananpandya Thanks Manan :)
Solid
@zerotox @mananpandya
totally fair, Manan — appreciate the perspective. Our intention wasn’t to dismiss the creativity or effort behind tools like Lovable, but to highlight the limitations we’ve seen when trying to scale or ship serious products. We’ve just seen too many people forced to rebuild from scratch.
Solid is built for those who want to vibe and deploy production-grade software without trade-offs. That said, we love the energy of the whole community — and your comment means a lot. Thanks for the thoughtful pushback 🙏
We think people are being misinformed of what they are building.
Here is a chatgpt explanation on the differences between lovable and a real full-stack app: https://chatgpt.com/share/68beb9...

Oh you actually let us own 100% of our app and deploy anywhere... That’s huge for avoiding all those vendor headaches. Seriously —how do you handle migrations if we outgrow Postgres?
Solid
@cruise_chen yep! It’s a Dockerized Node.js + Postgres stack, so you fully own the codebase and infra. If you outgrow Postgres, you can swap it. Migrations are handled via Prisma, and you can customize or switch ORMs if needed. You’re never locked in.
Can I plug in my own APIs/AI models or am I limited to the ones Solid integrates with?
Solid
@igorsorokinua its a real frontend, backend and database. Like a real engineer would build if you hired one. Not a prebuilt limited solution. You can do anything with Solid
Congrats on the launch, and a nice punch "Build real Web Apps with AI, not lovable toys" haha.
Solid
@tonkinai 😂😂😂
Really like how Solid sets itself apart with production ready code. One thing I’m curious about, do you see this being used mostly for MVPs that can later scale, or as a true production tool teams can rely on from day one?
Solid
@nelsonnn000 Great question! 🙌 The answer is both:
Many use Solid to get an MVP live fast — and then keep scaling on the same codebase (no rewrite needed).
Others jump straight into production with Solid because the stack (Node.js, Postgres, React, Dockerized) is what their teams would use anyway.
The whole point is: speed without throwaway code. 🚀
From a developer’s perspective, it’s currently not feasible to build production-grade applications of significant scale (e.g., 50k+ lines of code) entirely with AI. The limitations are fundamental: automated testing is not reliable across frontend or backend, tooling for validation is immature, and there’s no true modularity. In practice, AI cannot consistently generate isolated, testable components that integrate seamlessly into larger projects. These challenges are architectural rather than superficial—switching databases (e.g., Postgres vs. MongoDB) does not address the core issues. When claims suggest otherwise, it’s often more of a sales pitch than a realistic assessment of current capabilities.

@sergey_glukhov 🙏 Totally agree that most “AI builders” today generate prototypes that break at scale. That’s exactly why we built Solid differently. We have been two years working on stealth. 🥷
