pricing

One price. Unlimited bandwidth.
From $0.99. Speed-tiered. Never data-capped.

Every tier ships with unlimited data transfer. You pay for a public IP and speed — not for gigabytes. ngrok charges $30/mo for 1 TB. We charge $0 for that TB, forever.

3-Year pricing available on Micro, Spark, Launch, Pulse, Pulse+IPv4, Relay, Surge.

personal — entry-level public IPv6

Personal tiers: unlimited data transfer · IPv6 reachable · cancel anytime

the bandwidth difference

We don't meter bandwidth. Ever.

We never charge you for data — ever. Our tiers are speed-limited, not data-capped. The @blockzy testimonial of "14 TB egress last month. Bill didn't move" is not unusual.

faq

Common questions.

01

Is bandwidth really unlimited?

Yes. Our tiers are speed-limited (100 kbps to 1 Gbps depending on plan) but there is no monthly data cap. The @blockzy testimonial of "14 TB egress last month. Bill didn't move" is not unusual.
02

What's the difference between shared and isolated?

Shared (Micro / Free / Spark / Launch) puts multiple customers on the same relay with per-peer rate limits. Pulse and up gives you your own isolated network segment (per-peer, kernel-enforced) — no other customers can reach your traffic.
03

Can I run a mail server?

With caveats. Pulse+IPv4, Relay, Surge, Fleet, and Command include a dedicated IPv4 — required for SPF/DMARC/IP reputation. However, outbound SMTP (port 25) is blocked at the relay level on all tiers. You must route outbound delivery through a smarthost (e.g. Postmark, SES, or your ISP's relay). Inbound mail on port 25 is unblocked. Shared-network tiers are not suitable for mail servers.
04

Can I run game servers?

Yes. UDP is fully supported on all tiers. Minecraft, Valheim, Factorio, CS2, Palworld — all work. Game servers connect directly to your public IP, not through a proxy.
05

Do you support IPv6?

Every container gets at least one IPv6 /128 regardless of tier — from 2 IPs on Micro up to thousands on Surge. IPv4 depends on plan: Pulse+IPv4, Relay, Surge, Fleet, and Command include dedicated IPv4(s); Micro / Free / Spark / Launch / Pulse are IPv6-only.
06

Can I cancel anytime?

Yes. Monthly plans cancel immediately at the end of the billing cycle; annual and 3-year plans are refundable within the 14-day money-back window. Your network is decommissioned and all peer data destroyed within 24h of cancellation.
07
Why is the annual / 3-year price not just N× the monthly?
Annual gets you roughly two months free (~16% off). 3-year pricing locks the rate for 36 months and saves ~37% versus monthly. Both waive the setup fee on tiers that have one.
08
What does the IPv4 setup / provisioning fee cover?
There are two components: a $29 one-time setup fee (activation, onboarding — waived on annual and 3-year plans) and an IPv4 provisioning fee (covers the upstream IPv4 lease cost, non-refundable). Pulse+IPv4 / Relay / Surge: $29 setup + $3 provisioning. Fleet: $49 setup + $15 provisioning. Command: $99 setup + $30 provisioning. Pulse (IPv6-only) has the $29 setup fee but no provisioning fee. The provisioning fee is always charged regardless of billing period.
09
Is the bandwidth per-peer or shared?
On Micro / Free / Spark / Launch, each peer gets its own rate limit at the plan's throughput tier (e.g. Launch = 100 Mbps per peer, kernel-enforced). On Pulse and above, you get your own isolated network segment — the listed throughput is yours alone, not shared with other customers. If you need guaranteed speed on a specific IP, add a per-IP bandwidth guarantee after signup.

Do you accept Bitcoin?

Yes — Lightning Network annual billing is available at sidecar.network/btcpay. One payment covers 365 days of access. Available on Micro, Spark, Launch, and Pulse tiers. Monthly and 3-year billing use PayPal (credit/debit card).
