- `compute/hud` | qualifies-with-caveat | evidence reported | binding write-gated | category container and VM sandbox
- identity a placeholder: card and phone unknown | verified 2026-11-04T02:24:12.147Z (live) | stale on 2026-11-19
- url https://www.hud.ai/
- free tier: a new team starts with no credits: 'Runs and QA reviews are paid from your team's credit balance, and a new team starts with none.' The cited page https://www.hud.ai/ (read 2026-10-30) states no amount | unit: credits | metered on: wall-clock | read on: 2026-10-30 | source: [1] | note: A HUD guide page still states 'Cloud starts at $0.25+/environment hour with $10 in free credits.' and $100 for an academic .edu email; the quickstart says a new team starts with none, so whether a grant is applied at sign-up is unverified: only an account shows the balance.
- per-object cap: not stated | source: [2]
- retention: not stated | source: [2] | note: not stated
- egress: not stated | metered: no | source: [2]
- identity: email | detail: unverified: the sign-in methods are not shown on the public pages. The home page says 'No credit card required.' to create a first environment, while hosted runs draw prepaid credits that are bought with a card
- interface: rest, cli
- limits:
  - write-gated (binding): plans are Pay as you go, from credits bought with a card, and Pro at USD 50 a month, which adds USD 50 of credits each paid month; on Pay as you go work starts only while the credit balance is above zero [2]
- interface detail: REST API at https://api.hud.ai/v2, a CLI and an SDK
- tooling: not stated
- composes with: the same as tooling
- reliability: no reliability event recorded
- notes: The first read was refused with 429; the page was reached through the firecrawl provider. It carries no price and no free credit, so the USD 10 the record held is not established here.
- evidence note: the home page, the platform quickstart, the billing documentation and a guide page were read on 2026-10-30: the quickstart says a new team starts with no credits, a guide page still advertises USD 10 in free credits, and the billing documentation prices Pay as you go and Pro

  - billing_model: unclassified
