A year or so ago, the build vs. buy conversation was largely about time and budgets. Building took months, a lot of resources. Buying took days to go live. The math was simple.
That math has changed. With the right prompts and a clear enough spec, you can have a functional chat layer running before lunch. The speed and resource gap is mostly closed.
So the question isn't whether you can build it - you probably can. The question is what it costs to keep it working once real users start depending on it.

What your score means
0 - 4 Yes: Lightweight use case
You're likely building a contained utility. The scope is clear, the stakes are low, and vibe coding probably won't create meaningful debt as long as scope stays frozen.
Verdict: Vibe code it.
A handful of users. No compliance requirements. Chat that needs to exist but doesn't need to be extraordinary. This is exactly the environment where moving fast and iterating freely makes sense. Build something functional, validate your assumptions, and revisit the architecture later if the product grows into it.
The one caveat: ‘scope stays frozen’ is key. The moment you start getting new requirements, more users, new feature requests, compliance questions - revisit your score.
5 - 9 Yes: System in disguise
You're not building ‘just chat’. You're building a growing real-time system. Technical debt will compound unless carefully managed.
Verdict: Vibe code carefully - or be safe and just buy.
This is the range where teams tend to underestimate the problem. The prototype works. The demo goes well. But somewhere between ‘this works’ and ‘users depend on this daily,’ the surface area expands in ways that weren't obvious upfront.
Real search across long histories touches your storage layer and indexing strategy. Accurate unread counts across devices require careful event handling. Threads that hold context need architectural decisions made early. Moderation that worked on day one starts showing gaps as usage patterns shift.
None of it is unmanageable. It just requires someone to manage it continuously, not just at launch.
If your team has the bandwidth and the appetite, build carefully with scale in mind from the start. If that bandwidth is already spoken for, the math on buying starts to look more favorable than it did at the beginning.
10 – 15 Yes: Infrastructure ownership
This is production-grade, real-time infrastructure. You now own scale, reliability, security, and long-term maintenance. At this point, it's not vibe coding anymore it's an infrastructure decision.
Verdict: Buy. Don't build. (Unless your entire product is just chat, of course)
What you're describing isn't a chat feature. It's a communication layer that users depend on and that has real consequences when it misbehaves. Delivery guarantees. State recovery. Role-based permissions. Compliance obligations. Integration with the rest of your stack.
Each of those requirements is solvable. But each one also requires ongoing ownership: someone watching the system, handling edge cases, keeping up with platform changes, responding when something breaks quietly in a way that's hard to reproduce.
That's infrastructure work. And the question isn't whether your team can do it it's whether it's the best use of their capacity when a well-built solution exists and chat isn't what makes your product distinct.
So, vibe code or buy?
Count your Yes answers. Read your verdict. Trust the score.
If you're in the 0-4 range, move fast and don't overthink it. If you're in the middle, move carefully and stay honest about your maintenance bandwidth. If you're above 10, the infrastructure decision is already made. What's left is deciding who owns it.
If buying makes more sense, you know where to find us.
If your score said vibe code it, that's a fair call. CometChat has a set of skills to help you move faster: pre-built UI kits, composable messaging components, and the foundational pieces that take the most time to get right. You own the build. You just don't start from zero.
