Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
curl
- Open-source with no vendor pricing: curl is free and open-source under GPL 3.0; no subscription or licensing costs apply
- Commercial support costs hidden: site references 'commercial support available' but pricing is not detailed or accessible from homepage
- No SaaS model: curl is a command-line tool and library; costs are limited to optional commercial support contracts (pricing unknown)
- Self-support burden: free software means customers rely on community forums or undisclosed commercial support pricing
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- Pricing is entirely unpublished, so cost comparison against competing processors requires a sales process.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.
