The short version

  • Only Lovable has a free tier, so it costs nothing to try first.
  • Each has a real cost: Lovable credit-metered rather than unlimited: Free plan gets 5 build credits/day capped at 30/month, plus 20 cloud-hosting credits/month and 4 AI-feature credits/month; Proto.io prototypes live in the vendor cloud and offline export is a higher-tier feature, so the ability to archive completed client work is a plan-level decision rather than a given.
  • They diverge on capability: Lovable covers Natural language programming, Proto.io covers Event and condition system.
  • 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.

Lovable

  • Credit-metered rather than unlimited: Free plan gets 5 build credits/day capped at 30/month, plus 20 cloud-hosting credits/month and 4 AI-feature credits/month
  • Credits expire: monthly plan credits expire after 2 months unused, annual-plan credits expire 1 month after the annual period ends, and all credits are non-refundable
  • Not open source; only the legacy precursor CLI gpt-engineer is open source (MIT), and that repo was archived read-only on 2026-04-22
  • Hosting is free only for smaller apps; significant traffic or size draws additional charges from the credit balance

Proto.io

  • Prototypes live in the vendor cloud and offline export is a higher-tier feature, so the ability to archive completed client work is a plan-level decision rather than a given.
  • Design is done elsewhere and interaction is rebuilt here, so every change to the visual design has to be reapplied by hand and the two artefacts drift apart.
  • The event and condition model is layer based, so a genuinely complex flow becomes a large tree of triggers that nobody but its author can audit.
  • Editor seats are priced individually and viewer access is limited on lower plans, so opening review to a wide stakeholder group pushes you up a tier for people who never edit anything.
  • The market standardised on Figma, so hiring people who already know Proto.io is progressively harder and every new researcher is a training cost.

Answered from the vendors’ own pages

Lovable: What is included in Lovable's free plan?

The free plan includes 5 build credits per day (up to 30 per month), 20 Cloud credits per month, and 4 AI feature credits for trying features in apps. All plan members can access unlimited workspace members.

Source
Proto.io: Can it replace Figma?

No. It has no design system or file-handoff role. It sits alongside Figma for the prototypes Figma cannot express.

Lovable: How do credits work in Lovable's paid plans?

Lovable uses a credit-based model where costs depend on monthly credit allocation rather than per-seat pricing. Build tasks consume variable credits ranging from 0.50 to 1.70 credits depending on complexity, or 1 credit per message in Plan Mode.

Source
Proto.io: What happens to prototypes if we stop paying?

They stop being accessible unless you have exported them, and offline export is restricted to higher plans, so plan archiving before you cancel.

Lovable: Do credits expire in Lovable?

Yes, credit expiration depends on the plan: monthly plan credits expire 2 months after issuance, annual plan credits expire 1 month after the annual period ends, and top-up credits expire 12 months from purchase. Daily grants expire daily with no rollover.

Source
Proto.io: Is it worth learning now that InVision has gone?

If your work is usability research on conditional flows, yes. If you need click-through demos of static screens, Figma already does that at no extra cost.

Lovable: Are there additional costs for app hosting on Lovable?

Most small and new apps run free under included grants, but larger apps with significant traffic incur charges against the credit balance.

Source
Lovable: Does Lovable offer educational discounts?

Yes, a student discount is available with a valid university email.
