  • They diverge on capability: Ably covers Pub/sub messaging, Column covers National bank charter.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Ably

  • Standard and Pro plans layer usage-based charges for messages, connection minutes, and data transfer on top of the base subscription, adding cost complexity.
  • The jump from Standard ($29/month) to Pro ($399/month) is steep for teams needing more than 10k connections but not full Pro capacity.
  • 24/7 mission-critical support and 99.999% uptime SLAs are reserved for the custom-priced Enterprise tier.

Column

  • Column publishes no pricing whatsoever, so there is no way to model cost before a sales process, and terms are negotiated per programme which favours larger, more sophisticated buyers.
  • Onboarding is bank diligence rather than vendor sign-up, and programmes routinely spend several months on compliance review, flow of funds documentation and volume forecasting before the first live transaction.
  • Column selects its customers and declines many, so the charter advantage is only available to programmes it considers acceptable risk, which excludes most early-stage teams.
  • It is United States only, so any programme with international account or local payment needs must add a second banking relationship and reconcile across both.
  • Being the bank means Column also carries the bank's regulatory constraints, so product changes that affect risk, such as new customer segments or higher-risk flows, need approval rather than a configuration change.

Column: Is Column actually a bank?

Yes. It is a nationally chartered, FDIC-insured bank, which is why there is no sponsor bank behind it.

Yes, the free plan includes 200 concurrent connections, 500 messages per second, and 6 million messages per month with community and best-effort email support.

Those are technology providers that connect you to a separate sponsor bank. With Column the API provider and the depository institution are the same company.

Beyond plan limits, Ably charges usage-based rates of $2.50 per million messages, $1.00 per million connection minutes, $1.00 per million channel minutes, and $0.25 per GiB of data transfer, with volume discounts available.
