The short version

  • Only Pusher has a free tier, so it costs nothing to try first.
  • Each has a real cost: Pusher the free Sandbox plan is capped at 100 concurrent connections, which is quickly outgrown by production apps.; Sila no pricing is published, so you cannot compare Sila against Moov or Dwolla without entering two sales processes, and small programmes frequently find the monthly minimum dominates their cost at low volume.
  • They diverge on capability: Pusher covers Pub/sub channels, Sila covers ACH origination.
  • 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.

Pusher

  • The free Sandbox plan is capped at 100 concurrent connections, which is quickly outgrown by production apps.
  • Pricing jumps sharply between tiers (e.g. $49 to $99 to $299), leaving few options for teams with moderate but growing usage.
  • Priority support with faster response times costs an additional $3,000/month on top of plan pricing.

Sila

  • No pricing is published, so you cannot compare Sila against Moov or Dwolla without entering two sales processes, and small programmes frequently find the monthly minimum dominates their cost at low volume.
  • Sila is materially smaller and less well capitalised than the banking-as-a-service names it competes with, which matters because your customer funds and your payment rails depend on the vendor still trading in three years.
  • The sponsor bank behind your programme determines what you can offer and how fast you can change it, and bank partnerships in this sector have been reshuffled repeatedly since 2023, so a bank change during your contract is a realistic risk rather than a theoretical one.
  • Coverage is United States only, so any product with cross-border ambitions needs a second payments vendor and a second reconciliation process from the outset.
  • Onboarding involves compliance diligence on your own programme, and teams routinely underestimate this, with weeks lost between signing and first live transaction while policies, flow of funds diagrams and BSA arrangements are reviewed.

Sila: Does Sila require a sponsor bank?

Yes. Funds sit at a partner bank, and which bank that is affects your product features and your regulatory exposure, so ask before signing.

Pusher: Can I change or cancel my plan?

Yes, customers can log into the dashboard and adjust their plan at any time, including upgrading, downgrading, or cancelling.

Source
Sila: Is Sila still operating?

Yes. It continues to trade and announced an API integration with GBank in 2025 covering ACH, RTP and FedNow.

Pusher: How is usage metered?

Usage is measured by concurrent connections and messages per day; a message counts both the publish and each delivery, so publishing one message to 50 subscribers counts as 51 messages.

Sila: What does it cost?

Sila does not publish rates. Expect per-transaction pricing plus a monthly minimum, quoted after a compliance conversation.
