Facts

Free allowance
1M requests + 400,000 GB-s/month
Plan limits
Per account · source-code deploys · card required; automatic overages
Storage
1,024 MiB temporary root disk per instance; 100 MiB upload zip / 500 MiB code limits. Persistent storage is separate.
Account
Scaleway account and valid card to create cloud resources; €1 refundable verification authorization.
Retention
No fixed Free-tier expiry; functions scale to zero when idle. Idle function and account-retention policy not fully established.
Custom domain
Scaleway function endpoint and documented custom-domain mapping using your own registered domain; registration not free.
Password protection
Handler-level access control possible; simple viewer password on Free not evidenced.
Billing
Metered pay as you go above 1M requests or 400,000 GB-s/month per account. Mandatory card; provisioned minimum instances are charged separately even while idle. Optional storage/services can add charges; no hard spending cap verified.
Execution
HTTP functions; request timeout 10 seconds to 60 minutes; 6 MiB request payload; one concurrent request per instance and up to 50 instances/function. Scales to zero after 15 minutes idle.

Worth knowing

Use min-scale 0: minimum warm instances incur provisioned-resource charges outside the advertised execution allowance. Card required and automatic overages; allowances are shared across the account function usage. Requests stop after at most 60 minutes and local disk is temporary.

How we match

Choose the kind of thing you made and the features you need. The results respond to the capabilities recorded in our directory.

Each result explains its fit or mismatch. Unverified commercial-use permission is marked for a terms check. Unknown free features don’t count as confirmed fits.

Apps can run in the browser, as serverless functions, or on a persistent server. The second step changes with your choice: web pages or file links for sites and files, runtime options for apps. For agents and tools, choose an agent service, MCP server, or code sandbox. A sandbox or serverless endpoint is not a continuously running process. In each group, select several to see hosts that support any selected option. Leave them blank to explore broadly; your agent can check the runtime before publishing. Docs & media candidates also need an exact file-format and size check. Commercial mode removes records with documented personal or non-production restrictions; it does not certify permission on other hosts.

Open a host to read its limits and sources. The agent brief packages your choices and those limits into instructions you can paste into your agent. It does not publish anything.

Each record has its own review date (October 11–29, 2026); deployments, privacy, support, and uptime have not been tested. There are no paid placements or affiliate links in this edition.
