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; OpenAI API cost scales with tokens rather than with seats, so a successful feature's bill grows with its adoption, and an interface that lets users paste long documents has no natural ceiling on spend unless you build one yourself.
  • They diverge on capability: Lovable covers Natural language programming, OpenAI API covers Text and reasoning models.
  • Prices and features above were last checked on 30 August 2026.

What people use each for

  • Consumer community and content platformsnot OpenAI API

OpenAI API

  • Retrieval-augmented question answering over internal documents, using the embedding and generation models togethernot Lovable
  • Extracting structured records from unstructured text, where schema-constrained output removes most of the parsing problemnot Lovable
  • Prototyping a language feature quickly to find out whether it is worth the cost of a self-hosted alternative laternot Lovable

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

OpenAI API

  • Cost scales with tokens rather than with seats, so a successful feature's bill grows with its adoption, and an interface that lets users paste long documents has no natural ceiling on spend unless you build one yourself.
  • Models are deprecated on the vendor's timetable, and a fine-tuned model built on a retired base goes with it, so the tuning work and the data curation behind it must be redone rather than migrated.
  • Behaviour shifts between model versions in ways no test catches unless you wrote one, so prompts tuned over months against a particular snapshot can regress quietly on migration, which makes an evaluation suite a prerequisite rather than an improvement.
  • It cannot run inside your own network, so data residency requirements, air-gapped environments and contracts forbidding third-party processing rule it out regardless of the provider's own security posture.
  • You inherit its availability and its rate limits, so a provider incident is an outage in your product and a traffic spike can be throttled at precisely the moment the feature is proving itself.

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
OpenAI API: Is my data used to train the models?

API inputs and outputs are not used for training by default, which differs from the consumer product. Retention periods and enterprise terms change, so read the current data usage policy rather than trusting a summary.

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
OpenAI API: Can I run these models on my own hardware?

No. The weights are not distributed. If self-hosting is a requirement, you are looking at open-weight models instead, with the operational and quality trade-offs that implies.

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
OpenAI API: How is it priced?

Per token, with input and output priced differently and each model priced differently. Batch processing and cached input prefixes reduce it. The practical consequence is that your bill is a function of prompt design, not just of request count.

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
OpenAI API: What is the difference from Azure OpenAI Service?

The same model family delivered by Microsoft under an Azure contract, with Azure identity, networking and regional controls, and a different release cadence for new models. Enterprises with an Azure agreement often choose it for procurement and data residency reasons rather than technical ones.

Lovable: Does Lovable offer educational discounts?

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

Source
OpenAI API: How do I keep the cost under control?

Cap input length, cache repeated prefixes, route easy requests to smaller models, use the batch path where latency does not matter, and set per-user limits before launch rather than after the first surprising invoice.
