  • Each has a real cost: PubNub free plan storage history is limited to 7 days, which is short for apps needing longer message retention.; TrueLayer variable recurring payments, the strongest reason to choose TrueLayer, is a UK construct, and European businesses expecting the same capability in their market will not get it on the same timetable.
  • They diverge on capability: PubNub covers Pub/sub messaging, TrueLayer covers Pay by bank.
  • 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.

PubNub

  • Free plan storage history is limited to 7 days, which is short for apps needing longer message retention.
  • MAU-based pricing means costs scale directly with user growth, which can be less predictable than flat message-based pricing.
  • Pro-tier custom pricing above 50,000 MAU requires contacting sales rather than self-serve checkout.

TrueLayer

  • Variable recurring payments, the strongest reason to choose TrueLayer, is a UK construct, and European businesses expecting the same capability in their market will not get it on the same timetable.
  • Payment conversion varies substantially by bank, and a bank with a slow or broken authentication journey drags results down regardless of vendor, so aggregate coverage numbers say little about your actual mix.
  • Pay by bank has no chargeback mechanism, which merchants like until a customer disputes a purchase and finds no scheme protection, making it a poor fit for categories where buyers expect card style recourse.
  • Pricing is unpublished and varies by market and product, so multi-country merchants cannot model cost without a full sales engagement and often find rates differ significantly between countries.
  • Open banking authentication requires the customer to leave the checkout and authorise in their banking app, and that redirect remains the largest source of drop-off compared with a stored card.

Answered from the vendors’ own pages

PubNub: What does PubNub cost?

PubNub offers a free plan for up to 200 MAU or 1 million transactions, a Starter plan at $98/month for 1,000 MAU, and custom Pro pricing for larger volumes, e.g. around $550/month for 10,000 MAU.

Source
TrueLayer: Is VRP available outside the UK?

No. Variable recurring payments are a UK capability. EU adoption is on a slower path, with UK commercial VRP expanding into ecommerce during 2026.

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

Yes, the free plan supports up to 200 monthly active users or 1 million transactions, includes 1GB of data storage retained for 7 days, and requires no credit card.

Source
TrueLayer: What does TrueLayer cost?

Not published. Per-payment fees are quoted by volume, market and product, usually with a platform component and a minimum commitment.

PubNub: How is usage metered?

PubNub bills primarily by Monthly Active Users, defined as a unique user who connects at least once in a billing cycle; messages are bundled into MAU pricing with no separate per-message fees, and overage is billed proportionally.

Source
TrueLayer: Are there chargebacks on pay by bank?

No. Bank transfers have no card scheme chargeback mechanism, which removes that cost but also removes buyer recourse, so it suits some categories and not others.

TrueLayer: Which countries are covered?

The UK plus a substantial set of European markets under PSD2, though bank-level coverage and conversion vary by country and should be checked for your specific mix.
