The short answer

Choose Render if…

Workloads that need real background workers and persistent processes alongside web services, deployed from a repository or a Dockerfile. Managed Postgres and static sites run on the same platform.

Editorial · Palash Bagchi · approved

Choose Fly.io if…

Workloads that ship as Docker images and need placement in particular regions. Billing is purely usage-based with no plan tiers, which suits spiky or region-pinned traffic better than a flat monthly fee.

Editorial · Palash Bagchi · approved

Consider something else if…

  • Render: Free web services spin down after 15 minutes without traffic, which makes the free tier unsuitable for anything that must answer immediately.
  • Fly.io: You want a predictable flat bill rather than charges that track the resources provisioned for each app.

Documented by only one.

These criteria are published by one provider and not the other. An absence here means we have not found a source, not that the feature is missing — except where we say we read the other provider's own page on a given date and it does not state it. Those rows lean, and the provider can correct them with a link.

Egress over allowanceFly.io: Egress to the public internet is $0.02/GB in North America and Europe, $0.04/GB in Asia Pacific, Oceania and South America, and $0.12/GB in Africa and India.
Storage (entry plan)Render: No persistent disk is included on any instance type, including the entry `0.5c-512mb` plan; services run on an ephemeral filesystem unless a persistent disk is attached separately
Sites or apps includedRender: 25 total services on the Hobby workspace plan (Render's entry workspace tier, compute billed separately); also limited to a single team member
Monthly visits capRender: No request-count cap is published; traffic is capped by outbound bandwidth, 5 GB/month included on Hobby and 25 GB on Pro.
Included bandwidthRender: Hobby: 5 GB; Pro: 25 GB; Scale: 1 TB; Enterprise: Custom
File, inode or volume limitFly.io: 8 GB rootfs (deployed image) limit per Machine, platform-wide on all plans; exceeding it fails the image push at deploy time
Build allowanceRender: 500 build-pipeline minutes a month on Hobby, 1,000 on Pro, 5,000 on Scale. Minutes, not builds.
Concurrent buildsRender: One active build per service, platform-wide on all plans; a new build cancels the in-progress one for that service
CPU time limitFly.io: Platform-wide, per Machine size: shared vCPUs get a 5ms CPU quota per 80ms period (6.25%); performance vCPUs get the full 80ms. Quotas are shared across a Machine's vCPUs, and tasks are throttled for the rest of the period once the quota is reached.
Streaming response limitFly.io: No duration or size ceiling documented. Streaming works, but Fly Proxy buffers responses before compressing them, so progressive server-side rendering needs Content-Encoding: none set on those responses.
ContainersRender: Supported
Uptime SLARender: Enterprise only, and custom-priced. Hobby, Professional and Organization publish no uptime SLA, and no percentage is given for the Enterprise one.
Audit logsRender: Built-in audit logging and monitoring for platform events.Fly.io: not stated on its own page when read on 2026-09-21 — corrections welcome · every such claim about Fly.io.
Response time commitmentFly.io: 36-hour first response on Standard, the cheapest paid support plan at $29/month.
HIPAARender: Meet SOC 2 Type 2, HIPAA, ISO 27001, and GDPR requirements without overhead.Fly.io: not stated on its own page when read on 2026-09-21 — corrections welcome · every such claim about Fly.io.

Free tier: Render or Fly.io?

Render: Yes

Fly.io: No

When you exceed a cap: Render or Fly.io?

Render: Pipeline minutes: overage is auto-purchased, but with no payment method or once the monthly spend limit is reached Render stops running pipeline tasks, builds included.

Fly.io: No plan cap to exceed — Fly bills per second for provisioned resources. The only documented enforcement is unspecified automated scaling limits, which surface as an error message (platform-wide, all plans)

Should I choose Render or Fly.io?

Pick Render if Workloads that need real background workers and persistent processes alongside web services, deployed from a repository or a Dockerfile. Managed Postgres and static sites run on the same platform.

Pick Fly.io if Workloads that ship as Docker images and need placement in particular regions. Billing is purely usage-based with no plan tiers, which suits spiky or region-pinned traffic better than a flat monthly fee.
