Hyperbolic vs Koyeb

Hyperbolic

The API serves its own OpenAPI 3.1 document without a key, lists GPU prices on an open endpoint and dates the removal of legacy paths at 1 March 2027. API keys carry no scopes and can delete the account, rental creation has no idempotency key, and renting needs a browser signup and a $5 deposit.

Koyeb

H100 at $2.50 and H200 at $3.00 an hour, billed per second. Changelog silent since 27 February 2026 and no CLI release since 12 May 2026.

Hyperbolic

1. Read GET /v2/on-demand/rental-options first. It needs no key and lists what can be rented now, with costPerHourCents per GPU configuration.
2. Send rentalType and gpuCount to POST /v2/on-demand/rentals. Region defaults to us-central-1 and GPU type to h100, so set both from the options list.
3. List active rentals before retrying a failed create call. There is no idempotency key and every ready rental bills hourly.
4. Save an SSH public key with POST /v2/ssh-keys before renting. Without sshPublicKeyIds the newest saved key is attached.
5. Do not create reserved rentals unless asked. They are paid in full up front and cannot be terminated early.

Koyeb

1. Pass dry_run on service create or update to validate the definition before anything deploys
2. Page service lists with limit and offset and filter by statuses instead of fetching everything
3. Expect the first request after deep sleep to take 1 to 5 seconds and retry once with a timeout
4. Set --min-scale 0 on GPU services so idle instances stop billing
5. Re-check the Mistral transition before building anything long-lived on it
