Best hosting
for vibe-coded apps
Updated 2026-09-18. Vercel is the pick for most projects. Here is how the options compare, and how to run whichever you choose through a single Squiid key.
Short answer
- Our pick: Vercel. Git push to production with preview URLs per branch, which is exactly the loop an agent-assisted project runs in. Framework detection means zero config for Next.js, Astro, Vite and most of what agents generate.
- Runner-up: Netlify. The same deploy-on-push model with a generous build allowance, good form handling and edge functions. Pick it if you are not on Next.js.
- Pick something else when: Railway or Render when you need a long running server, a worker or a database container rather than functions, and Fly.io when you want your app close to users in several regions or you need real containers with persistent volumes.
Host the app your agent wrote on Vercel. Connect the repository, push, and you get a URL. Every branch gets its own preview, which matters more than usual when an agent is writing the code, because you want to look at a change before it reaches production.
How to choose a hosting for an AI-coded app
Does it deploy from a git push with no config?
Agent-written projects change shape often. A host that detects the framework and builds without a config file means the agent can restructure the app and the deploy keeps working. A host that needs a bespoke build file means you maintain that file forever.
Preview deploys per branch
The single most useful safety feature for agent-assisted work. Every pull request gets its own URL, so you can click through what the agent built before merging. If a host does not do this, you are testing in production.
Functions or a long running process?
Serverless functions are ideal for request and response work and scale to zero. They are a poor fit for websockets, long jobs and background queues. If your app needs a process that stays alive, use a platform that runs containers instead of trying to bend functions into it.
Where do the environment variables live?
You will set the same variables in three places: your machine, the host, and any preview environment. Fewer variables means fewer mistakes. Running services through one gateway key reduces that list to effectively one line per environment.
What does traffic actually cost?
Bandwidth, function invocations, build minutes and image optimisation are billed separately on most hosts. A viral demo is the classic way to discover this. Set a spending cap where the host supports one, and prefer prepaid credits that pause over a plan that keeps billing.

Why run your hosting through Squiid
One login instead of one per vendor. Squiid carries 5 hosting options here and every other layer of the stack beside it. You create one account, click the service you want, and Squiid provisions it upstream. No separate signup, no separate password, no second dashboard.
One bill, at the provider's price. Usage is paid from prepaid Squiid credits at par: $1 of credit is $1 at the provider, with no markup on what the provider charges. The free plan is $0/month with a 15% fee on credit top-ups and a $50 minimum top-up. Solo is $19.97/month and its top-up fee starts at 8%, falling to 6.5%, 5% and 3.5% as trailing 30-day API spend passes $100, $500 and $2,000. Team is $29.97 per seat per month for seats 1-5, $24.97 for seats 6-20 and $19.97 above that, with the same ladder one point lower. Custom pricing is 3% or less against a commitment. Services that are sold as a monthly subscription, such as Vercel's paid plan, pass through on your Squiid invoice at the provider's own price with no fee on top.
Squiid holds the upstream key. The provider credential lives in Squiid, not in your repo, not in a chat window and not in a screenshot. Your project gets one variable, SQUIID_API_KEY, and that is the only secret an agent ever needs to see. Rotating it is one click and does not touch the provider.
It works with every coding agent. Point the SDK base URL at https://api.squiid.io/v1/<service>/ and send Authorization: Bearer $SQUIID_API_KEY. Claude Code, Cursor, Codex, Gemini CLI, Copilot, Windsurf, Cline, Devin, Replit, v0 and Lovable all read environment variables the normal way. See the gateway convention.
Running out pauses, it never deletes. Squiid warns you at 75%, 90% and 100% of your balance. At zero, calls pause instead of overdrawing, and your data stays where it is. Auto top-up is optional and takes a hard monthly cap. See spend controls.
Set it up in 3 steps
Add Vercel in the dashboard
Create a Squiid account, open the catalogue, and click add on Vercel. Squiid creates the upstream account or project for you and holds the credential.
Put one variable in .env
Copy your Squiid key and add SQUIID_API_KEY=sq_live_… to your project's .env. Delete any provider keys you were carrying. Nothing else changes.
Point your agent at the gateway
Tell your agent that calls go to https://api.squiid.io/v1/vercel/ with Authorization: Bearer $SQUIID_API_KEY. Most SDKs take a base URL option, so it is a one-line change.
In practice that is one line in your project:
SQUIID_API_KEY=sq_live_xxxxxxxxxxxxxxxxxxxxThen every call your app or your agent makes goes to the gateway with that one key:
curl https://api.squiid.io/v1/vercel/... \
-H "Authorization: Bearer $SQUIID_API_KEY"Questions people ask
Where should I deploy an app I built with an AI coding agent?
Vercel for anything frontend-first or Next.js shaped, which is most agent-generated code. Connect the repo, push, and each branch gets a preview URL. Add Vercel through Squiid to keep the deploy token out of your repo and the hosting bill on the same invoice as your database and email.
Vercel or Netlify for a vibe-coded app?
Vercel if you are on Next.js, since it is the framework Vercel maintains. Netlify if you are on Astro, Vite, SvelteKit or plain static output and want a larger free build allowance. The deploy model is the same on both and switching later is mostly a DNS change.
Do I need a separate host if my app has a background worker?
Often yes. Serverless functions time out and do not stay resident, so queues, cron and websockets belong on Railway, Render or Fly.io, or on a workflow service. See the observability and workflow guide for the durable job options.
How do I stop a hosting bill from spiking overnight?
Run hosting through Squiid credits. Usage draws down a prepaid balance, you get alerts at 75%, 90% and 100%, and at zero the service pauses rather than continuing to bill. Auto top-up is optional and takes a hard monthly cap you choose.
Can my agent deploy for me?
Yes, if it can run shell commands or call the host API. Give it SQUIID_API_KEY and the gateway path https://api.squiid.io/v1/vercel/ rather than a raw deploy token, so a leaked prompt cannot be used to push to your production project.
One key for your hosting.
