Pricing that scales with you
Four plans with hard memory caps. Always-on and extra regions are usage too — they draw down the same plan, and what you add beyond it is billed by size: an extra agent costs from $3.50/mo.

Frequently Asked Questions
What counts as overage?
Usage beyond your plan's allowance is billed on top of the base price. An extra agent costs from $3.50/month on auto-sleep (a 256 MB agent) and more for larger sizes and always-on, up to your plan's usage limit. The table on this page lists every size.
Are memory limits enforced?
Yes. Each plan has a hard cap on per-agent memory (256 MB on Free, 2 GB on Starter, 4 GB on Performance). Exceeding the cap requires an upgrade.
Can I change plans anytime?
Yes. Upgrade or downgrade from your dashboard. Changes apply to the current billing cycle.
Is there a free trial?
The Free plan is a permanent tier — 1 agent, 256 MB, 1 region, no time limit. No payment method required to start.
How is task compute priced?
The same way every other agent is priced: by its memory, per region. There is no separate task rate and no separate allowance. A task agent's machine sleeps between runs, so an agent that runs occasionally costs what its size costs; one whose tasks keep it awake continuously converges on the always-on price for that size.
Why developers choose Aetherfy
Hard caps, not surprise bills
Each plan has a hard memory ceiling. You can't accidentally deploy a 4 GB agent on Starter — the platform refuses with a clear upgrade message.
Multi-region when you need it
Starter is one region, one focus — your whole account (agents and data) runs where your first resource lands, in iad, fra, or sin. Performance unlocks multi-region: agents in different regions, or a single agent running across iad, fra, and sin simultaneously with replicated data, for high availability and low-latency reads everywhere.
Always-on or auto-sleep
Default agents auto-sleep when idle. Flip always-on for production workloads with steady traffic — billed as a transparent monthly addon.
Extra agents from $3.50/mo
An extra agent costs the same on every plan, by its size, per region per month. No tiered penalties for going over your allowance. Starter offers up to 2 GB, Performance up to 4 GB.
