Pricing

nfltr is free until further notice, and we will announce any change before it applies. This page describes how charging will work once it starts. Prices are not set yet, so this page has none.

Prepaid credit

When charging starts, it is prepaid: an account buys credit first, and its use draws the credit down. There are no monthly packages and no subscription.

Prices will be set from what the service costs to run, plus a small margin. For always-on agents, a site with steady traffic, bulk TCP traffic and fleets of agents, that puts them below paid hosted tunnel plans for the same use. Where another service's free plan already covers a use, nfltr is not cheaper there.

What is metered

The relay counts each account's use hour by hour, in three kinds:

• Connected time. How long each of the account's agents stays connected to the relay. An agent is anything that holds a connection to the relay for the account, such as nfltr up, nfltr http or a node.
• Traffic. The bytes the relay carries for the account, in each direction, counted separately for each kind of traffic: web links and shares, end-to-end encrypted shares, TCP tunnels, connect sessions (nfltr dial, connect: mappings and SSH through nfltr ssh-proxy), agent-to-agent calls (including peer-to-peer sessions the relay carries when the two machines cannot connect directly) and WireGuard tunnels. A peer-to-peer session that connects directly does not pass through the relay, so its bytes are not counted. Each kind costs a different amount to carry, so each can have its own rate.
• Stored data. The bytes the account keeps in mailboxes and blobs, for each day they are kept.

Model use is not metered. Agents run Claude Code under the Claude account whose credentials each machine uses, and nfltr never bills that use.

When the credit runs out

When the balance reaches zero, the account gets a notice and its agents keep working for a grace period. Use during the grace period is taken from the next top-up. If the grace period ends without a top-up, the account's agents and sessions stop until it is topped up. No bill arrives afterwards.

A stopped account's data in mailboxes and blobs is kept for a while after it stops; the notice says until when, more notices come before that date, and the data is deleted after it.

Hobbyist tier

A free Hobbyist tier covers personal use, and commercial use is allowed on it. Its limits are announced together with the prices.

Plans

Paid plans differ only in how they are invoiced. Every plan has the same features.

Statements

Each account's dashboard shows its use, by unit, by agent and by share.
