Unlimited data delivery
We don't charge for egress, data delivery, fan-out, active users, concurrent users, clients, connections, seats, apps, sources — or monthly bills under $5/month.
Powered by CDN caching
Electric delivers real-time data over HTTP, using CDN caching and request collapsing to handle millions of concurrent readers without proportional infrastructure cost. Your costs scale with writes, not users.

Frequently asked questions
What counts as a write?
A write is a message written to a durable stream, up to 10 KB in size. Messages larger than 10 KB are automatically chunked into multiple write units — for example, a 1 MB message counts as 100 write units.
Why don't you charge for reads or egress?
Electric delivers real-time data over HTTP using CDN caching and request collapsing. This means concurrent readers are handled at the CDN layer without proportional infrastructure cost. Your costs scale with data written, not with the number of users reading it.
What are service costs?
Services that run additional infrastructure carry an additional cost on top of the base write rate. Postgres Sync adds +$2 per 1M writes, metered on the filtered shape log output (the writes emitted to shapes, not the raw replication input). This gives an effective rate of $3 per 1M writes for live Postgres changes. Initial sync and snapshots are billed at the base rate only.
How does the monthly fee work on Pro and Scale?
The monthly fee on Pro ($249) and Scale ($1,999) acts as a prepaid usage credit. Your usage is calculated at the discounted rate (10% off for Pro, 20% off for Scale) and if it stays under the monthly fee, you pay only the fee. Usage above the fee is billed as overage.
Do I need a credit card for the PAYG plan?
No. You can sign up and start building without a payment method. We waive monthly usage under $5. If your usage grows past $10 (or $5 if your workspace was blocked in the previous billing month), we'll ask you to add a payment method to continue.
How is retention measured?
Retention is measured in byte-seconds — the amount of data stored and for how long. This is converted to GB-months for billing at $0.10 per GB-month. Retention accounts for TTL-based automatic deletion, so you only pay for data that's actually retained.
Can I upgrade or downgrade my plan?
Yes. You can upgrade from PAYG to Pro, PAYG to Scale, or Pro to Scale at any time — upgrades take effect immediately with prorated charges. Downgrades take effect at the end of your current billing period, provided your usage is within the target plan's limits.
What are the concurrent reader limits?
Concurrent readers per stream are monitored by tier — 100 for PAYG, 1,000 for Pro, and 10,000 for Scale. These are soft thresholds used for monitoring; they are not hard-enforced at launch. If you consistently exceed your tier's threshold, we'll reach out to discuss upgrading.
