The short version

  • Only Apidog has a free tier, so it costs nothing to try first.
  • Each has a real cost: Apidog free plan is capped at 4 users, limiting larger teams from using it at no cost.; Increase the published per transaction rates exclude a monthly platform fee that Increase states varies by use case, so the transparent price page cannot produce a total cost and the material part of the deal is still negotiated privately.
  • They diverge on capability: Apidog covers API design and documentation, Increase covers ACH origination and receipt.
  • 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.

Apidog

  • Free plan is capped at 4 users, limiting larger teams from using it at no cost.
  • Faster scheduled imports and unlimited projects require the Professional tier or higher.
  • Smaller community and plugin ecosystem compared to long-established tools like Postman.
  • Advanced enterprise security controls require the top-tier Enterprise plan.

Increase

  • The published per transaction rates exclude a monthly platform fee that Increase states varies by use case, so the transparent price page cannot produce a total cost and the material part of the deal is still negotiated privately.
  • Free allowances are deliberately small at ten account numbers and five physical cards, so any programme issuing accounts or cards at volume moves to quoted pricing almost immediately.
  • Banking is provided through partner banks, so programme approval, compliance obligations and the ability to launch at all depend on a bank relationship you do not control, and post-Synapse bank risk appetite has tightened considerably.
  • The API deliberately exposes payment rail mechanics rather than smoothing them, which is correct engineering but means a team without payments expertise will build reconciliation and return handling wrongly and only discover it when funds go astray.
  • Coverage is United States only, so a company with international payout needs runs a second provider and reconciles two ledgers, and the single API argument disappears at the first cross border customer.

Answered from the vendors’ own pages

Apidog: What does Apidog cost?

Apidog offers a free plan for up to 4 users, with paid per-seat plans at roughly $9/month for Basic, $18/month for Professional, and $27/month for Enterprise when billed annually.

Source
Increase: Does Increase publish its pricing?

Partly. Per transaction fees for ACH, wires, RTP, FedNow and cards are listed publicly. The monthly platform fee is not, and it is described only as varying by use case.

Apidog: Is there a free plan, and what are its limits?

The free plan supports up to 4 users with access to core design, documentation, mocking, and testing features.

Source
Increase: Who holds the deposits?

Partner banks, not Increase itself. That relationship determines your programme approval, your compliance obligations and your risk if the bank changes appetite.

Apidog: Can I try paid plans before subscribing?

Paid plans include a 14-day free trial, giving teams full access to premium features before committing to a subscription.

Source
Increase: Is it international?

No. Increase covers United States rails only, so cross border payouts require a second provider.

Increase: How is it different from a middleware BaaS platform?

It exposes the rails rather than abstracting them, showing real return codes and settlement timing. That suits teams who understand payments and punishes teams who do not.
