The short version

  • Only Liveblocks has a free tier, so it costs nothing to try first.
  • Each has a real cost: i2c developer experience lags API-native competitors, and teams expecting Stripe-grade documentation and sandboxes find an enterprise integration project instead.; Liveblocks on the Free plan, each metered feature has a hard cap and simply pauses when exceeded rather than allowing overage.
  • They diverge on capability: i2c covers Configurable product engine, Liveblocks covers Realtime presence and cursors.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

i2c

  • Developer experience lags API-native competitors, and teams expecting Stripe-grade documentation and sandboxes find an enterprise integration project instead.
  • Implementations lean on i2c or partner professional services, so timelines and costs are set by a services queue rather than by your own engineering speed.
  • Pricing is per active card and per transaction with monthly minimums, none of it published, so comparing bids requires modelling your own portfolio carefully.
  • Configuration flexibility means product behaviour lives in platform settings rather than in your repository, which complicates version control, testing and audit trails.
  • As a private company with a broad global footprint, regional support depth is uneven, and a programme in a smaller market may get thinner service than a flagship account.

Liveblocks

  • On the Free plan, each metered feature has a hard cap and simply pauses when exceeded rather than allowing overage.
  • The jump from Pro ($30/month) to Team (starting at $600/month) is steep for teams that outgrow Pro but don't need full Team scale.
  • Multi-region hosting and SCIM provisioning are Enterprise-only and require custom pricing.

Answered from the vendors’ own pages

i2c: Does i2c issue the cards itself?

No. It processes; issuance sits with a bank or licensed issuer, and in most markets you need that relationship separately.

Liveblocks: What does Liveblocks cost?

Liveblocks offers a Free plan with hard usage caps, a Pro plan at $30/month ($25/month billed annually) including $30 in monthly credits, a Team plan from $600/month, and custom Enterprise pricing.

i2c: Can it handle revolving credit?

Yes. Credit, instalments and buy-now-pay-later sit on the same platform as debit and prepaid, which is unusual among modern processors.

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

Yes, the Free plan includes 10 projects, 3 dashboard seats, 10 simultaneous connections per room, 3,000 collaboration minutes, 200 comments, and 1GB of realtime data storage, with features pausing once a cap is hit.

Source
i2c: Is it self-serve?

No. Expect a configuration-led implementation with professional services rather than signing up and calling an API.

Liveblocks: How is usage metered?

Paid plans include monthly credits covering collaboration minutes, comments, and storage; usage beyond the credit is billed at metered rates such as $0.002 per collaboration minute and $0.01 per comment, with credits resetting each billing cycle without rollover.
