Stacker
No-Code
Permissioned portals over data that stays in Airtable, Salesforce or Postgres
- From
- On request
- Rated
- -
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; Stacker there is no source export and no self-hosting, so leaving means rebuilding the entire interface and permission model elsewhere, even though the underlying records remain yours.
- They diverge on capability: Lovable covers Natural language programming, Stacker covers Per-record permissions.
- 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
Stacker
- There is no source export and no self-hosting, so leaving means rebuilding the entire interface and permission model elsewhere, even though the underlying records remain yours.
- Performance is bounded by the data source, so an Airtable base near its row limit or an API under rate limiting produces a slow portal that no amount of Stacker configuration will fix.
- Pricing distinguishes internal editors from external portal users, so a portal that succeeds by adding hundreds of light-touch external users can end up costing more than the internal system it fronts.
- Custom logic is limited to the actions and conditions the builder exposes, so anything resembling a calculation engine or a branching multi-step approval hits a wall and needs an external automation tool bolted on.
- It is a portal and CRUD tool by design, with no offline mode, no native mobile application and no real reporting layer, so it will not be the only system a growing operation runs.

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.
SourceStacker: Where does my data live?
In the source you connect: Airtable, Salesforce, HubSpot, Google Sheets or your own Postgres. Stacker reads and writes to it rather than becoming the system of record.
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.
SourceStacker: Can I export the app if I cancel?
No. The data stays in your source system, but the interface, permissions and workflows are Stacker configuration and do not come with you.
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.
SourceStacker: Is it suitable for hundreds of external users?
Technically yes; check the pricing arithmetic first, because external portal users are charged separately and that is where the bill grows.
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.
SourceStacker: Will it replace Airtable?
No, it sits in front of Airtable. If the base itself is at its limits, the fix is moving the data to Postgres rather than changing the portal.
Lovable: Does Lovable offer educational discounts?
Yes, a student discount is available with a valid university email.
