The best cloud stack for vibecoding
Pick a stack you can deploy, secure, test, and recreate. A quick public URL is useful; it is not evidence that generated code is ready for customers.
Prompt-driven development can shorten the path from an idea to an application. The hosting choice still has to fit its runtime, data, identity, and cost model. My starting recommendation is a managed backend and a compatible frontend host for a small web prototype. Treat that as a workflow preference, not a benchmark showing one provider wins every comparison.
Write the requirements before accepting the generated stack
Ask the tool what it generated: a static site, a server-rendered application, an API, a persistent background process, or a combination. List external services and environment variables. Inspect the package manifest and deployment instructions. If the application needs a permanent server process, a static host alone will not run it.
- Data: identify the database engine, files, retention, and migrations.
- Identity: distinguish sign-in from permission to access a specific record or organization.
- Execution: list runtime features, duration limits, scheduled tasks, and background jobs.
- Cost: include model calls, database usage, file storage, hosting, and network transfer.
- Recovery: decide how to recreate the application and restore its data.
Four useful stack shapes
| Shape | Why evaluate it | What remains your responsibility |
|---|---|---|
| Managed Postgres backend plus frontend host | Relational data and a hosted deployment workflow; Supabase bundles additional backend features | Schema, authorization, secrets, migrations, backups, and hosting-plan terms |
| Workers, D1, and static assets | An application suited to Cloudflare's runtime and SQLite-based data service | Runtime compatibility, identity integration, query design, and each service's usage limits |
| VM with containers | A persistent process or a goal of learning server operation | OS updates, firewall, TLS, service recovery, and data backups |
| Managed AWS or Azure services | A platform, identity, networking, or managed-service requirement already points there | Resource scope, access policy, deployment configuration, and the complete bill |
Supabase and Neon both offer Postgres, but their surrounding products and configuration are different. Do not assume that choosing a database automatically gives the application a complete authentication and authorization design. Verify the integration against the provider's current documentation.
Vercel's Hobby plan is restricted to personal, non-commercial use. A prototype intended for commercial use needs an appropriate plan or another host with suitable terms. Cloudflare also has separate request, execution, database, and storage limits; “no egress bill” is not a description of every service's complete price.
For a server experiment, Oracle currently documents an Always Free A1 allowance equivalent to 2 OCPUs and 12 GB for an Always Free tenancy. Capacity and idle-reclamation rules matter. AWS's current new-customer Free plan lasts up to six months or until its credits are used; an old twelve-month comparison is not universal.
Generated code still needs an authorization test
A login screen can work while every signed-in user can read everybody else's data. Create two disposable accounts with separate records and test cross-account access. Try the API directly, without the browser interface. Attempt reads, writes, and deletions against another user's record and verify the server rejects them.
For a Supabase application, review row-level security policies and the roles used by requests. Keep privileged backend credentials out of browser code. For Firebase, review the database security rules instead of leaving development access in place. The authorization mechanism depends on the backend; a frontend hiding a button is not an access control.
Keep API keys for paid model calls on a trusted server-side path. Add authentication and bounded usage there. Check error paths as well as successful requests. A retry loop can multiply paid calls even when the user sees only one failed answer.
Run a release rehearsal
- Recreate from the repository. Start with a clean checkout and documented configuration. If it depends on an unexplained manual change, record that change.
- Apply a migration. Test schema changes on disposable data and keep a recovery procedure.
- Inspect the deployed application. Check private routes, environment variables, logs, and error messages for accidental secrets.
- Test predictable failures. Use invalid input, an unavailable dependency, a denied record, and a repeated request. Confirm that responses are safe and understandable.
- Restore a backup. Confirm that the app works against restored data, not just that an export file exists.
Keep these results beside your deployment notes. A green build proves that the build finished; it does not prove that data is private or recovery works. For the cloud concepts behind those checks, read Class 4 and Class 32.
When should the stack change?
Change when you can name a requirement the current configuration cannot meet: a supported runtime, an identity feature, a data-residency obligation, a performance target, or a cost you have measured. First check whether an appropriate plan on the same provider solves it. Managed platforms can support substantial applications; growth does not automatically require moving to another cloud.
Compare migration work with the expected benefit. Include data export, identity, URLs, downtime, rollback, and the team's familiarity with the target. Test a representative slice before committing. Choosing Postgres can help with data portability, but extensions, auth, and surrounding services still need migration work.
Common questions
What should I choose for a first web prototype?
A managed backend and a compatible deployment host are a useful starting point. Confirm runtime, authorization, pricing, and recovery before sharing it widely.
Must I move to AWS or Azure after a prototype grows?
No. Move for a specific unmet requirement or measured benefit. Compare suitable plans on the current provider first.
Does AI-generated code remove the need for cloud skills?
No. You still need to understand access, deployment, resource costs, and recovery. Test the generated application rather than inferring safety from a working demo.
