Wildflower Computer supports 12 adapters. The generated capability directory covers every one; 5 direct providers also have evidence-backed behavior guides. Provider selection is explicit at creation and remains fixed for that sandbox. - [AWS AgentCore](https://wildflower.computer/docs/reference/providers/agentcore/) — agentcore - [Blaxel](https://wildflower.computer/docs/reference/providers/blaxel/) — blaxel - [ASCII Box](https://wildflower.computer/docs/reference/providers/box/) — box - [Cloudflare Sandbox](https://wildflower.computer/docs/reference/providers/cloudflare/) — cloudflare - [E2B](https://wildflower.computer/docs/reference/providers/e2b/) — e2b - [Novita Agent Sandbox](https://wildflower.computer/docs/reference/providers/novita/) — novita - [Daytona](https://wildflower.computer/docs/reference/providers/daytona/) — daytona - [Modal](https://wildflower.computer/docs/reference/providers/modal/) — modal - [Runloop](https://wildflower.computer/docs/reference/providers/runloop/) — runloop - [Smol Machines](https://wildflower.computer/docs/reference/providers/smol/) — smol - [Fly.io Sprites](https://wildflower.computer/docs/reference/providers/sprites/) — sprites - [Vercel Sandbox](https://wildflower.computer/docs/reference/providers/vercel/) — vercel ## Detailed behavior guides **Blaxel** Preview / contract-tested / `blaxel` Persistent Blaxel sandboxes addressed through an API key and workspace. ImageRuntime image supported LifetimeTimeout sent as runtime TTL OutputSeparate stdout and stderr A workspace is required on every lifecycle request. - [Detailed Blaxel support](https://wildflower.computer/providers/blaxel/) **E2B** Preview / contract-tested / `e2b` Persistent sandboxes created from an E2B template. ImageTemplate ID supported LifetimeTimeout in seconds OutputSeparate stdout and stderr Defaults to the base template and a 300-second lifetime when omitted. - [Detailed E2B support](https://wildflower.computer/providers/e2b/) **Daytona** Launch tier / live-proven / `daytona` Persistent sandboxes created from a container image. ImageContainer image supported LifetimeRounded up to TTL minutes OutputCombined output in stdout Wildflower Computer generates a one-line Dockerfile from the image value. - [Detailed Daytona support](https://wildflower.computer/providers/daytona/) **Runloop** Preview / contract-tested / `runloop` Persistent Runloop Devboxes created from an optional Blueprint. ImageBlueprint name supported LifetimeMaximum 172800 seconds OutputSeparate stdout and stderr The default starter image is used when a Blueprint name is omitted. - [Detailed Runloop support](https://wildflower.computer/providers/runloop/) **Fly.io Sprites** Launch tier / live-proven / `sprites` Persistent Sprites with a fixed environment and automatic sleep. ImageFixed environment LifetimeNo timeout option OutputSeparate stdout and stderr A cold Sprite may report stopped and wakes on its first command. - [Detailed Fly.io Sprites support](https://wildflower.computer/providers/sprites/) ## Blaxel behavior - The image is a Blaxel runtime image and defaults to blaxel/base-image:latest. - An optional timeout in seconds is sent to Blaxel as the runtime TTL. - The adapter returns the provider process stdout, stderr, and exit code through the shared execution result. - The provider credential is a blaxel api key. ## E2B behavior - The image field is interpreted as an E2B template ID. It defaults to base when omitted. - The timeout is a sandbox lifetime in seconds and defaults to 300 when omitted. - The adapter preserves separate stdout and stderr streams and returns the command exit code. - The provider credential is a e2b api key. ## Daytona behavior - The image field is a container image. The adapter generates a one-line Dockerfile using that image. - The API accepts seconds and the adapter rounds them up to whole Daytona TTL minutes. - Daytona returns combined command output. The adapter places it in stdout and returns an empty stderr. - The provider credential is a daytona api key. ## Runloop behavior - The image field is interpreted as a Runloop Blueprint name. The default starter image is used when omitted. - The timeout becomes the Devbox maximum lifetime and cannot exceed 172800 seconds. - The adapter waits for command completion and returns stdout, stderr, and the exit status. Truncated output is reported as an error. - The provider credential is a runloop api key. ## Fly.io Sprites behavior - Sprites uses a fixed environment. The adapter rejects image rather than silently ignoring it. - Sprites automatically sleeps and persists until deletion. The adapter rejects timeout. - The adapter preserves separate stdout and stderr frames and returns the command exit code. - The provider credential is a fly.io sprites api token. > **Support does not mean failover** > > The API and adapter contract tests cover these providers. Wildflower Computer does not automatically retry an operation on a different provider or migrate sandbox state. > **Live proof is narrower than adapter coverage** > > Daytona and Fly.io Sprites are the initial launch tier with a current full private-staging lifecycle smoke. The remaining adapters are preview: their lifecycle boundaries are contract-tested without current live provider credentials. > **Lifecycle support is not billing-data support** > > Every provider currently has a normalized published-price estimate, but none is presented as provider-reported per-sandbox cost. Some providers require distinct billing scope; others expose dashboard or aggregate-only data. Review the [complete provider observability matrix](https://wildflower.computer/docs/provider-observability/) before building usage analytics or customer-facing cost UI. For tested upstream contracts and machine-readable evidence, use the [provider compatibility matrix](https://wildflower.computer/compatibility/) and [OpenAPI downloads](https://wildflower.computer/openapi/).
