The short version

  • Only Ably has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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minutes, and data transfer on top of the base subscription, adding cost complexity.; Thredd pricing is entirely unpublished, so cost comparison against competing processors requires a sales process.
  • They diverge on capability: Ably covers Pub/sub messaging, Thredd covers Issuer processing.
  • Prices and features above were last checked on 1 September 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.

Thredd

  • Pricing is entirely unpublished, so cost comparison against competing processors requires a sales process.
  • The 2023 rebrand from GPS to Thredd means research under either name alone can miss relevant material, and partner or press references before 2023 will still say GPS.
  • Issuer processing does not include the banking licence itself, so a fintech still needs a separate BIN sponsor or bank partner, adding a second relationship to manage.
  • As shared infrastructure behind many fintech brands, an outage or processing delay at Thredd becomes a simultaneous incident for every programme running on it, with limited visibility for any single customer into root cause.
  • Its verticals span crypto, BNPL and remittance broadly, so depth of specialist support in any one vertical may be thinner than a processor focused narrowly on that niche.
