The short version
- Only Pusher has a free tier, so it costs nothing to try first.
- Each has a real cost: Astra push-to-card costs materially more per transaction than ACH, so a platform that switches all payouts to instant sees payment costs rise sharply, and the usual answer of charging the recipient for speed only works where recipients will pay.; Pusher the free Sandbox plan is capped at 100 concurrent connections, which is quickly outgrown by production apps.
- They diverge on capability: Astra covers Instant disbursements, Pusher covers Pub/sub channels.
- 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.
Astra
- Push-to-card costs materially more per transaction than ACH, so a platform that switches all payouts to instant sees payment costs rise sharply, and the usual answer of charging the recipient for speed only works where recipients will pay.
- Original Credit Transaction support is not universal across card issuers, so a proportion of payouts fall back to slower rails and you must build and explain a two speed experience rather than promising instant to everyone.
- The programme depends on Cross River Bank as sponsor, a bank with concentrated fintech exposure and a documented regulatory history, so a single supervisory action on that institution is a direct operational risk to your payouts.
- Nothing is published on pricing, and per transaction economics vary by rail and volume, so small platforms cannot estimate cost before a sales conversation and have limited leverage in it.
- FedNow reach still depends on the recipient bank participating, so instant account-to-account is not available to every recipient and the routing logic has to degrade gracefully, which is more integration work than the single API framing suggests.
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.

Answered from the vendors’ own pages
Astra: Who is the sponsor bank?
Cross River Bank. All banking and payment services run through that relationship, so the bank should be part of your diligence rather than an implementation detail.
Pusher: What does Pusher cost?
Pusher Channels offers a free Sandbox plan (200k messages/day, 100 connections) and paid plans starting at $49/month for Startup, scaling up through Pro, Business, and several higher tiers up to $1,199/month, plus custom Enterprise pricing.
SourceAstra: Do I have to prefund payouts?
Not necessarily. Astra offers a net debit arrangement where disbursements settle against a reserve rather than a permanently funded float account, which is the main working capital argument for the product.
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.
SourceAstra: Is every payout instant?
No. Push-to-card requires the recipient card issuer to support Original Credit Transactions, and FedNow requires the recipient bank to participate. The rest fall back to ACH.
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.
SourceAstra: What does it cost?
Nothing is published. Pricing is per transaction and varies by rail and volume, and card rails cost considerably more than ACH.
