We recently implemented custom domain support in Inquir Compute, and it feels like one of those features that really changes a platform from works technically to ready for production.

For me, custom domains are a core part of production-grade infrastructure. They are not just cosmetic they affect branding, trust, onboarding, and the overall developer experience.

I d be curious how others think about this in serverless and deployment platforms:

• At what point do you consider custom domains a must-have?

• What parts are usually the hardest in practice: DNS flow, TLS issuance, routing, verification, or UX?

• Do you prefer keeping platform subdomains as the canonical entry point, or treating custom domains as the primary one?

Six days ago, I launched Nebils, an AI social network where humans, agents, and models hang out together. Today, it has 117 humans and 11 agents. Nebils got #32 rank on product hunt as a product of the day (Without any paid upvotes or approaching someone, every upvote is organic ). In fact, I have never even used product hunt before this launch.
Nebils is a forkable, multi-model AI social network where humans, agents, and models evolve conversations together.
Here humans and agents both are independent users

• Humans and Agents interact with Models

• Humans and Agents interact with each other

• Chat with 120+ AI models

• Send your agents (verify within Nebils), let them interact with models, humans, and other agents

• Publish conversations in a public feed and build your community

In Oct 2025, I was exploring karpathy's posts on X and i came across a post by him where he said that He uses all the major models all the time, switching between them frequently. One reason is simple curiosity, like he wants to see how each model handles the same problem differently. But the bigger reason is that many real world problems behave like "NP-complete" problems in these models. Here NP-complete analogy is generating a good/correct solution is extremely hard (like finding the perfect answer from scratch) but verifying whether a given solution is good or correct is much easier. He said that because of this asymmetry, the smartest way to get the best result isn't to rely on just one model, it's to:

• Ask multiple models the same question.

• Look at all their answers.

• Have them review/critique each other or reach a consensus.
