The short version
- Only Svix has a free tier, so it costs nothing to try first.
- Each has a real cost: Svix the Professional tier at 490 US dollars a month includes the same 50,000 messages as the free tier, so the upgrade buys SLA, throughput and retention rather than volume, which is a jarring step for a growing product.; Thredd pricing is entirely unpublished, so cost comparison against competing processors requires a sales process.
- They diverge on capability: Svix covers Automatic retries, 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.
Svix
- The Professional tier at 490 US dollars a month includes the same 50,000 messages as the free tier, so the upgrade buys SLA, throughput and retention rather than volume, which is a jarring step for a growing product.
- Only attempted messages count toward usage, but a customer with many subscribed endpoints multiplies a single event into many billable messages, and forecasting that fan-out before launch is difficult.
- The open source server is MIT licensed but trails the hosted product in features, so self-hosting is a fallback position rather than a genuinely equivalent option.
- Routing outbound customer traffic through a third party puts a vendor in the delivery path for events your customers may treat as contractual, which some security reviews will not accept.
- Payload retention is 30 days on the free tier and 90 on Professional, so anyone needing longer delivery history for audit must pay for Enterprise or log independently.
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- Pricing is entirely unpublished, so cost comparison against competing processors requires a sales process.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.
