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.; Yodlee ownership has changed twice in two years, from Envestnet to Bain Capital control and then to STG in 2025, so the roadmap is now set by a financial sponsor and long term product direction is harder to rely on than it was.
  • They diverge on capability: Svix covers Automatic retries, Yodlee covers Account aggregation.
  • 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.

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.

Yodlee

  • Ownership has changed twice in two years, from Envestnet to Bain Capital control and then to STG in 2025, so the roadmap is now set by a financial sponsor and long term product direction is harder to rely on than it was.
  • Parts of the connection estate still depend on credential based access, which banks and regulators are phasing out in favour of FDX APIs, so coverage will shift as institutions withdraw the older method and the migration is not under your control.
  • The platform predates modern API design and developers consistently find the integration heavier and the data model more idiosyncratic than newer aggregators, which lengthens build time.
  • Pricing is enterprise shaped with annual commitments and nothing published, so small and mid sized buyers have no anchor and cannot start without a sales cycle.
  • Investment data, document retrieval and analytics are licensed on top of core aggregation, so the capabilities that justify choosing Yodlee over a cheaper rival are the ones that raise the price above it.

Answered from the vendors’ own pages

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.

Yodlee: Who owns Yodlee now?

Private equity firm STG, which acquired it from Envestnet in a deal closing in 2025. Envestnet, itself taken private by Bain Capital and Reverence Capital in 2024, retained access through a partnership.

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.

Yodlee: Why choose Yodlee over Plaid?

Longer transaction history, deeper investment and held-away account coverage, and document retrieval. Those are wealth management and underwriting requirements rather than consumer fintech ones.

Svix: What counts as a message?

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

Yodlee: Does it still use screen scraping?

Parts of the estate rely on credential based connections, which the industry is phasing out in favour of regulated APIs. Ask for direct API coverage by institution before signing.

Svix: Does it handle inbound webhooks?

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

Yodlee: Is pricing published?

No. It is quoted by connected users, refresh frequency and data types, with investment data and document retrieval priced separately.
