Across the top-reviewed Unified API products, patterns cluster around three jobs: monetization infrastructure, AI/model orchestration, and business data connectivity. RevenueCat stands out for cross-platform subscriptions, entitlements, paywalls, and lifecycle analytics; Merge focuses on normalized SaaS integrations with secure auth and sync; liteLLM emphasizes provider-agnostic LLM routing, failover, observability, and cost control."

Recent launches

Recent Unified API launches skew toward AI routing and orchestration, with newer tools emphasizing provider switching, budgets, failover, and compliance, while adjacent entrants target specialized workflows like voice, web data, and embedded execution. GoModel and TrustedRouter focus on resilient multi-model access with governance or privacy controls, while HarnessRouter extends the pattern into managed agent runtimes and sandboxed task execution.

What do you use to vibe-code applications?

I have used a few products to vibe-code my applications. The first one I used was Chatgpt. From this, I created my first application and it had a very average UI. I was using nextjs for frontend and backend, so for me, the backend part took time but it was decent.
The second product which is good enough for me currently is Gemini. This creates a very good UI and backend at the same time. The first time I used it, it was a super upgrade in the UI. I also used Lovable to create one practice project, but I don't know why I did not used again.

I also heard people's suggestion of using different AI's like claude, cursor etc. but moving in to a different platform has some friction.
What AI is most used or easiest to build an application? I recently heard of a new AI called Emergent, which creates the whole application with a single prompt.

Would you rather use 5 tools to build an app, or one AI builder for the whole thing?

I ve been thinking about how messy the current build an app with AI workflow still is.

For a simple website or SaaS-style product, people often end up jumping between multiple tools:

one tool for UI generation
another for backend/database
another for auth
another for payments
another for deployment
and maybe something else for internal dashboards or admin tools

It works, but the workflow can get fragmented pretty quickly especially if you re not a full-stack developer.

If I told you that you could get AI infrastructure out of the box, what would you need?

Not another chatbot builder. Not another connect your API to an LLM tool.
I mean the boring, painful infrastructure that you don't want to build every time you ship an AI agent.

Things like:

Agent orchestration
RAG
900+ integrations
Evaluations
Observability & analytics
LLMOps
Payments & usage tracking

GoModel

Open-source, self-hosted OpenRouter. What would make you try it in prod?

Hi
Jakub here, solo founder from Warsaw. I built GoModel and I'm launching it here very soon. Show HN hit #4 in April.
GoModel is an open-source AI gateway in Go. You can think of it like a self-hosted OpenRouter. It's one OpenAI-compatible API for every model provider, with budgets, caching, guardrails, load balancing, and failover.

In March LiteLLM shipped a compromised PyPI release. Then Portkey went to Palo Alto and TensorZero stopped operating. People are looking for more robust alternatives and GoModel is one of them.

If you use LiteLLM today or are considering an AI gateway for internal use - what would make you try GoModel in prod?
Cost, data privacy, compliance, user interface - or is hosted just easier and you'd never bother?

Follow the page for the launch ping. Happy to answer any question.
