Paid plans start at $29/mo. There's also a free plan.
Ably is realtime infrastructure and APIs for delivering and syncing data across connected users and devices, including chat, collaboration, AI agent sessions, and database-to-frontend sync. It has a free tier, while Pro starts at $29 per month billed annually; Business is $349 per month billed annually, and Enterprise pricing is custom. The catch: Pro and Business each list 1K MAUs, so check that allowance against your growth forecast before treating the entry price as your likely bill.

03Which plan should you buy?
| If you are… | Get | Why |
|---|---|---|
| Building and testing | Free | Includes up to 500 MAUs, best-effort community and email support, and no commitment. |
| Launching a production app | Pro | Lists 1K MAUs, an email support SLA under one business day, and a 99.999% uptime SLO. |
| Scaling critical workloads | Business | Lists 1K MAUs, a service-impaired SLA under four business hours, 99.999% uptime SLA, SOC 2 report, and HIPAA BAA. |
| Custom workload requirements | Enterprise | Offers custom MAUs, faster support SLAs, SAML / SCIM / Okta SSO, and a dedicated Solution Architect and CSM. |
04Is Ably worth the money?
Ably's plan grid gives buyers useful distinctions: the paid tiers list support response terms and uptime commitments, while Business adds a SOC 2 report and HIPAA BAA. But Pro and Business both list only 1K MAUs, so the $29 starting price may not answer what a growing app will cost. We’d compare that allowance with your forecast and ask Ably about higher usage and add-on pricing before committing. Enterprise is a quote, not a price you can compare from the grid.
