Lambda Cloud vs Northflank

Lambda Cloud

H100 SXM at $3.99 and B200 at $6.69 an hour with per-minute billing. No scale to zero, autoscaling or endpoints; an idle VM bills until terminated.

Northflank

OpenAPI 3.0 with over 100 paths, enums and per_page, page and cursor on every list. No scale to zero for services; minimum instances must be at least 1.

Lambda Cloud

1. Call GET /instance-types first and read regions_with_capacity_available before trying to launch
2. Space launch calls 12 seconds apart; a sixth in a minute returns 429 with global/rate-limited
3. Branch on the error code, not the message or suggestion, which Lambda says may change
4. List instances before retrying a failed launch, since there's no idempotency key and a retry can start a second machine
5. Terminate the instance in a finally block; billing runs by the minute until you do

Northflank

1. Issue the agent a team token under an API role limited to one project, not a personal token
2. Read x-ratelimit-remaining and wait x-ratelimit-reset seconds on a 429; the default is 1,000 calls an hour
3. Page lists with per_page up to 100 and the returned cursor instead of numbered pages
4. Use a job, not a service, for anything that finishes; services bill until paused or deleted
5. Fetch any docs page with .md appended to get Markdown
