02What the plan grid doesn't tell you
MAU overages
The plans list MAU allowances, but Ably does not publish the charge for exceeding them. Ask how MAUs are counted and what happens above the allowance.
Annual commitment
Pro and Business prices are billed annually; Enterprise is annual billing only. Confirm contract terms and renewal conditions before budgeting.
Optional infrastructure
Dedicated cluster and PrivateLink/VPN are add-ons. Their prices are not published, so request a quote if your architecture needs them.
Usage and rate limits
The listed plans do not give a full usage-cost or rate-limit schedule. Ask Ably about message, connection and other limits relevant to your workload.
03Which plan should you buy?
| If you are… | Get | Why |
|---|---|---|
| Prototype or small app | Free | It includes all products and features up to 500 MAUs, with no commitment. |
| Startup launching production | Pro | $29 per month for 1K MAUs, billed annually, with a 99.999% uptime SLO. |
| Business-critical workloads | Business | $349 per month for 1K MAUs, billed annually, with a 99.999% uptime SLA, SOC 2 report and HIPAA BAA. |
04Is Ably worth the money?
Ably’s Free plan is a practical starting point for development and smaller applications: it includes all products up to 500 MAUs without a commitment. Pro begins at $29 per month for 1K MAUs, but its annual billing and undisclosed overage pricing make a production forecast essential. Business costs more, while adding a stated uptime SLA, SOC 2 report, HIPAA BAA and regional routing. Ask Ably for a written estimate based on expected MAUs and required add-ons before signing.
