The short version

  • Only Svix has a free tier, so it costs nothing to try first.
  • Each has a real cost: MX Technologies coverage is United States focused, so any product with European or other international users runs a second aggregator and reconciles two data models, which removes most of the single vendor argument.; 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.
  • They diverge on capability: MX Technologies covers Account aggregation, Svix covers Automatic retries.
  • 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.

MX Technologies

  • Coverage is United States focused, so any product with European or other international users runs a second aggregator and reconciles two data models, which removes most of the single vendor argument.
  • Nothing is published on price and contracts are enterprise shaped, so a small fintech cannot estimate cost or start building without a sales process, unlike self-serve competitors.
  • Data enhancement is the differentiator and is licensed separately from aggregation, so the quoted aggregation price is not the price of the product people actually buy it for.
  • Categorisation and merchant resolution are statistical and get business to business and unusual transactions wrong more often than consumer retail, so lending decisions built on categorised data need their own review layer.
  • As the United States moves to regulated API access, connection quality depends on what each institution exposes, and the long tail of small banks and credit unions remains the weakest part of any aggregator including this one.

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.

Answered from the vendors’ own pages

MX Technologies: What does MX do that Plaid does not?

It sells transaction cleansing, categorisation and merchant resolution as a first class product, including on data you already hold, which is why financial institutions rather than startups are its core customers.

Svix: How much does Svix cost?

Free up to 50,000 messages a month; Professional starts at 490 US dollars a month with the same included volume but better SLA and throughput.

MX Technologies: Does it cover Europe?

No. MX is United States focused. European coverage requires a different provider such as Tink.

Svix: Can I self-host it?

Yes, there is an MIT licensed server, but it lags the hosted service in features and has no SLA.

MX Technologies: Is pricing published?

No. Contracts are quoted by connected users, call volume and modules, with enhancement licensed separately from aggregation.

Svix: What counts as a message?

Attempted or transformed deliveries. Retries and messages filtered out because no endpoint subscribed are not charged.

MX Technologies: Does it use screen scraping?

It uses direct bank APIs where institutions expose them and credential based connections elsewhere. The credential path is being deprecated across the industry, and coverage quality now tracks which banks have real APIs.

Svix: Does it handle inbound webhooks?

Its focus is outbound sending on behalf of API providers, not receiving webhooks from third parties.
