# Free-first hosting and identity

> Prefer free tiers, avoid Amazon services and verify provider limits before deployment.

HAIP's reference deployment policy is free tiers first, with no Amazon services.
Local development uses Node/PostgreSQL and needs no cloud account. Cloudflare and
Clerk are candidates where their limits fit; prefer Azure if a paid service is needed.
No hosting, storage or identity account is provisioned automatically.

Cloudflare R2 Standard currently includes 10 GB-month of storage, one million Class A
operations and ten million Class B operations per month, with free egress. It is a
candidate for private, encrypted backups, with deletion by 30 days. An R2 uploader
is not included. [R2 pricing](https://developers.cloudflare.com/r2/pricing/).

R2 bucket-lock rules can be removed by administrators. They are not substituted for
the strict production requirement for independently administered immutable audit
storage. The optional Azure adapter checks locked retention, exact versions and
permanent safety holds. It is not assumed free and needs real deployment acceptance.

Clerk can be configured through the standard server-side OAuth/OIDC flow. Set the
exact issuer/client/callback, `HAIP_OIDC_DISCOVERY=oauth2` and
`HAIP_OIDC_CLIENT_AUTH=client_secret_basic` when using its OAuth metadata endpoint.
HAIP requests `openid`, retains its own secure sessions and requires operator-managed
identity mappings. The generic flow is tested; an actual Clerk account is not configured.

Vercel Hobby is intended for personal, non-commercial use. This reference service
also needs a persistent Node worker and PostgreSQL; it is not a drop-in serverless
function. Static documentation can use suitable existing/free hosting independently.

Recheck pricing, quotas and plan terms before deployment. Reaching a free-tier limit
does not authorise a paid upgrade. See the repository's `PROVIDERS.md` and
`deployment/acceptance.md` for the full choices and unrun checks.
