r4ck
Claude connectorCommunitySearch every server offer for sale (VPS, cloud, bare metal, GPU, PaaS) by spec, price and location, and compare providers.
r4ck is a search engine over server offers for sale: VPS, cloud instances, bare metal, GPU nodes, PaaS and shared plans, with the provider behind each one.
Read-only tools:
- Search offers with a sentence ("2 vcpu 4gb under $10 in germany") or explicit filters, and see how the sentence was understood
- Find the cheapest offers meeting a spec, ranked by estimated monthly USD
- Read one offer with its price history and similar offers, and compare up to 20 side by side
- List providers with their automation (API, CLI, Terraform, MCP), country and categories, and read one provider's offers
- Facet counts, index statistics, and current hosting deals
With an r4ck account key you can also save searches, manage invites and credit codes, and manage webhooks for new matching offers.
