In short

Fly.io runs Docker/OCI images as hardware-isolated Firecracker microVMs (Fly Machines) on its own hardware in 17 regions, billed per second, and sells Sprites: persistent Linux VMs that sleep when idle and are metered by CPU, memory and storage, marketed as computers for AI agents.

Read full summary

Fly.io deprecated its GPU Machines (A10, L40S, A100 40GB and 80GB) in February 2026; they became unavailable after 1 August 2026 and the GPU docs were removed on 5 August 2026. Fly.io is therefore a CPU-only option: relevant for hosting AI agents, MCP servers and app back ends that call external model APIs, not for self-hosted GPU inference or training.

Who it fits

Based on Fly.io’s public documentation, checked . We don’t score providers. How we build records

Suited to

  • Always-on or scale-to-zero AI agents (OpenClaw, Hermes Agent) that call external LLM APIs
  • Per-user or per-task agent sandboxes and MCP servers that need hardware isolation (Sprites or Machines)
  • Teams that want per-second CPU billing, EU regions (Amsterdam, Stockholm, Paris, Frankfurt) and a pre-signed GDPR DPA

Good fit for

  • AI agentsStrong fitOfficial Fly guides for OpenClaw and Hermes Agent; Machines with persistent volumes, per-second billing and auto-stop; Sprites (8 vCPU, 100 GB disk, no compute charge while idle, checkpoints) are designed for agent workloads; hardware-isolated Firecracker microVMs; agents must call external LLM APIs.
  • RAG applicationsSuitableApp layer on Machines plus Managed Postgres with pgvector (plans from $38/month) and the Tigris object-storage extension; embedding and generation models must come from external APIs or small CPU models because no GPUs are offered.

Look elsewhere for

  • TrainingNot suitableFly.io has offered no GPUs since 1 Aug 2026 (A10, L40S and A100 were retired); the largest CPU configuration is 16 performance vCPUs with 128 GB RAM.
  • Fine-tuningNot suitableNo GPU Machines are available; CPU-only Machines are not a practical fine-tuning target.
  • Batch inferenceNot suitableSelf-hosted model inference would be CPU-only. Machines can run batch jobs that call external model APIs, billed per second.
  • Real-time inferenceNot suitableNo GPU-backed serving. Machines can host the API or app layer in 17 regions and call hosted model APIs, but cannot serve LLMs on GPUs.

  • RenderingNot suitableNo GPUs are offered since 1 Aug 2026.
  • Private LLM hostingNot suitableWithout GPUs only small models on CPU are feasible (for example Ollama's CPU mode, not documented by Fly); larger private LLMs need a GPU provider.

Strengths and limitations

Summarised from the research record for Fly.io. We don’t score providers.

  • Official Fly.io guides for OpenClaw (with a Fly-published deploy script) and Hermes Agent
  • Hardware-isolated Firecracker microVMs; per Fly.io's compliance page, a SOC 2 Type 2 report, a pre-signed DPA and a pre-signed BAA
  • 17 regions, including four in the EU plus London
Show 2 more
  • Egress from North America and Europe at $0.02/GB; inbound traffic free
  • Sprites: persistent 8-vCPU Linux VMs with 100 GB storage and no compute charge while idle

Limitations

  • No GPUs: GPU Machines (A10, L40S, A100) became unavailable after 1 August 2026, ruling out self-hosted GPU inference, fine-tuning and training
  • Largest CPU configuration is performance-16x with 128 GB RAM ($1,104.32 per 30 days in iad/ewr)

  • Fly Volumes live on a single server (max 500 GB each) with no built-in replication; Fly advises at least two volumes per app
Show 4 more
  • The 99.9% uptime SLA with service credits applies only to Enterprise-plan customers
  • No ongoing free compute tier: the free trial ends after 2 Machine-hours or 7 days, whichever comes first (only small perpetual allowances remain, such as the first 10 GB of volume snapshots per month and the first 10 single-hostname certificates)
  • Fly Kubernetes is in closed beta and not recommended for critical production use
  • Product direction changed in 2026: GPUs retired and company focus moved to Sprites (July 2026); Fly.io staff state that Machines are not being wound down

Frameworks

How Fly.io works with common AI serving, agent and training frameworks. Support levels, strongest first: an official template, documentation, a community guide, or manual setup on a general-purpose machine.

Hosting

Support for running the framework itself on Fly.io.

OpenClaw hosting providers
Official template
Fly docs guide plus a downloadable deploy package (github.com/fly-apps/Openclaw-Fly-Deploy) whose script creates the app, volume and secrets; default shared-cpu-2x with 4 GB; bring your own LLM API key. Docs: Deploy OpenClaw on Fly.io (opens in a new tab)
Hermes Agent hosting providers
Documented setup
Official Fly docs guide using Nous Research's prebuilt image on a multi-container Machine with a 3 GB volume; dashboard reached through fly proxy rather than a public port. Docs: Run Hermes Agent on Fly.io (opens in a new tab)
Flowise
Community guide
Third-party guide with Dockerfile, fly.toml and a volume for Flowise's SQLite data. No official Fly guide found. Secondary source: Deploying Flowise to Fly.io (Blue Leaf blog) (opens in a new tab)
n8n
Community guide
Third-party repo with Dockerfile, fly.toml and step-by-step guide (last commit May 2024); it uses unmanaged Fly Postgres, which Fly lists as unsupported. No official Fly guide found. Secondary source: TheFSilver/n8nonflyio (community n8n on Fly.io repo) (opens in a new tab)
Ollama
Manual setup
Fly's 'Add Ollama' guide still specifies the retired a100-80gb GPU size, so it cannot be followed as written. Docs: Add Ollama - Fly.io (opens in a new tab)
MoreOllama documents a CPU-only Docker mode, so a CPU-only deployment on Machines is possible but undocumented by Fly and limited to CPU speed and at most 128 GB RAM.
vLLM
Not supported
No GPU Machines since 1 Aug 2026 and no Fly vLLM guide found. Whether vLLM's CPU-only build runs on Fly Machines is not verified. Docs: superfly/docs commit 84fd3d0: Remove deprecated Fly GPUs docs (#2449), 2026-08-05 (opens in a new tab)

Customer-managed keys (BYOK)
Partial
Your own key material is documented only for application-level encryption, through app-scoped 'secret keys' in the Machines API. Docs: Create or update a secret key - Fly.io Machines API (opens in a new tab)
MoreYou create or update a key with caller-supplied key material (POST /v1/apps/{app_name}/secretkeys/{secret_name}, body type + value), then encrypt, decrypt, sign and verify through the API. Volumes and databases are encrypted at rest with LUKS using platform-managed secrets (security and volumes docs), and no option to supply your own key for volumes, snapshots or Managed Postgres is documented. The OpenClaw and Hermes guides require your own LLM provider key, which is an API key for the model, not an encryption key.

Sources and verification

35 sources, accessed between 26 Sep 2026 and 20 Oct 2026. Official provider pages are listed first; the 6 secondary sources are labelled as such.

How we verify

Prices, regions, storage, features, framework support, SLA and support channels link to the page they were read from, and every price shows when it was checked. Fit labels, strengths and limitations summarise the same research record. The Fly.io record was last checked on 26 Sep 2026. A check date older than 7 days is marked “Stale” with an amber dot, and one older than 30 days “Needs refresh”.

Verification notes

On 26 September 2026 we checked every plan price, regional price and region in this listing against Fly.io's live pricing pages, documentation and status page. The status page also shows a Mumbai component that the docs region table does not list; the listing follows the docs. Not verified: which regions run Sprites, the prices of the Tigris storage extension and the status page's 90-day uptime figures. Later corrections are listed on the methodology page.
