Free tier	no free tier: 'New organizations don't have a free tier or a monthly free usage allowance.' A trial of up to 2 hours of Machine runtime or 7 days, no card to start it, card afterwards. unit none; metered on none
Price	none stated
Per-object cap	not applicable: the unit is a Machine, not an object
Retention	a stopped Machine bills only its rootfs at USD 0.15 per GB a month; volumes bill whether attached or not
Egress	outbound USD 0.02 per GB in North America and Europe, USD 0.04 in Asia Pacific, Oceania and South America, USD 0.12 in Africa and India; inbound free free_allowance: none after the trial
Identity	card no card to start the trial, which runs 2 hours of Machine runtime or 7 days; a card on file is required for most accounts afterwards; under USD 10 pre-authorisation after signup, cancelled immediately, which a bank may show for up to 10 business days; prepaid refused as a default or saved method but accepted to buy credits at a USD 25 minimum; debit is not stated
Limits	volume-quota no free allowance for new organizations; a 2-hour or 7-day trial is the whole of it source per-ip-shaping egress USD 0.02 per GB in NA and EU, USD 0.12 per GB in Africa and India source request-rate organizations may be subject to automated scaling limits to prevent abuse source The trial's 5-minute auto-stop is a hard cap on any single run, and the 2-hour total is shared across every machine launched.
Binding	volume-quota there is no recurring free meter at all, so the first billable second after the trial is the constraint.
Interface	rest, cli flyctl, a GraphQL API, and a Machines API
Tooling	flyctl, the Machines API, LiteFS; fly ssh console reaches a Machine
Composes with	the cheapest always-on container is USD 2.19 a month, and egress at USD 0.02/GB is the bill that follows
Reliability	Machines can auto-stop when idle, which leaves the app with no capacity until a request wakes it
Notes	The corpus record's verdict 'dead' contradicted its own note ('The free tier is withdrawn, not the product'). Corrected here. The trial detail also moved: the corpus said a card is required, and today's page says the trial starts without one. it is now quoted. The distinction that matters for a client with no credit card is that a prepaid card still buys credits at a USD 25 minimum, which keeps an app running even though the card cannot be saved.
Evidence rung	documented the free-tier question, the trial terms and the smallest always-on price are all on the pricing page read today \| Payment facts re-read on 2026-10-24: the card types, the hold and the identity gate each come from a first-party page quoted in evidence[].

Free tier	No. New organizations don't have a free tier or a monthly free usage allowance. A trial runs up to 2 hours of Machine runtime or 7 days, whichever comes first, with no card; after that a card is required. unit none; metered on none
Price	none stated
Per-object cap	not applicable
Retention	A stopped Machine keeps only its rootfs, billed at USD 0.15/GB/month; a Fly Volume is billed at USD 0.15/GB/month whether attached or not, including while the Machine is stopped.
Egress	Outbound data transfer is billed per GB, USD 0.02/GB in North America and Europe per the vendor's own worked example; inbound transfer, shared IPv4 and IPv6 are free. free_allowance: none stated for egress; inbound free
Identity	card Card at signup after the trial: 'All organizations (except for Linked Organizations) require a credit card on file.' The trial itself needs no card. No hold amount is published on the pricing page. Debit acceptance is not stated.
Limits	volume-quota outbound transfer billed at USD 0.02/GB in North America and Europe; no free egress allowance source per-ip-shaping UDP is not supported over a shared IPv4 or over IPv6; UDP needs a dedicated IPv4 at USD 2/month source not stated
Binding	volume-quota Egress is the meter with no allowance: a 24/7 machine that serves 1 TB a month adds USD 20 to a USD 3.74 bill, ten times the compute line.
Interface	unknown
Tooling	not stated
Composes with	not stated
Reliability	Billed by the second while the Machine runs; a stopped Machine bills its rootfs alone at USD 0.15/GB/month, so an idle box is not free.
Notes	The dossier's existing fly-machines record says `dead` because a free tier was refuted; the product is live and priced, so this record replaces that verdict with qualifies-with-caveat and the caveat is the card. Egress arithmetic: USD 0.02/GB x 1000 GB = USD 20 per TB, hence price_per_tb_month. The vendor quotes a monthly figure per 30 days (720 h), so 730 h is rate x 730/720: 512 MiB = 3.69 x 1.0139 = USD 3.74; 256 MiB = 2.19 x 1.0139 = USD 2.22. A persistent volume is not included; 1 GB adds USD 0.15, 10 GB adds USD 1.50. The 1 GB Machine is USD 6.70 per 30 days = USD 6.79 at 730 h, over the line. Not established: whether a debit card is accepted, and the smallest volume Fly will provision.
Evidence rung	documented Prices, the stopped-Machine rate, the dedicated-IPv4 price and the no-free-tier statement are quoted from the pricing page read today; VM-ness and the root shell from the Machines overview read today; the UDP restriction from the services page read today. What would raise it: a probe that starts a Machine and reads the invoice after 24 hours.
