Search either way round -- "Base44 vs Lovable" or "Lovable vs Base44" -- and the useful question is the same: who is going to use the software? If the answer is employees, access control decides it and Base44 leads. If the answer is customers, the look of the first draft decides it and Lovable leads. The old shortcut for this comparison, that Lovable makes you bring Supabase while Base44 includes a backend, is out of date and worth ignoring.
Base44 treats access control as a product feature rather than as code you write. Data is modelled as entities defined in JSON Schema, and the platform supplies CRUD, validation, and permissions at two levels: which rows a person can reach, and which fields inside those rows they can see. That second level is rarer than it sounds -- it is the difference between hiding a personnel record and hiding the salary column inside a record everyone else can read. Enterprise workspaces extend the same idea to sign-in, with OIDC single sign-on through providers such as Okta and Microsoft Entra ID plus SCIM user provisioning. Documented connectors reach Slack, Google Workspace, Snowflake, Databricks, Gmail, Resend and ElevenLabs. Visual polish is handled after generation, through an editor for colour, type and spacing, rather than through the original prompt. Base44 has been owned by Wix since 2025.
Lovable competes on the first draft. You describe the product, or hand over a screenshot or a specification document, and what comes back is presentable before you have adjusted anything -- which matters a great deal when the people judging it are customers rather than colleagues. Underneath sits Lovable Cloud, enabled by default, covering a relational database with security policies, authentication, file storage, edge functions, scheduled jobs, built-in AI, branded email and secret storage; pointing the project at your own Supabase instance is now an option rather than the standard route. GitHub sync runs in both directions on every plan including the free one, so a developer can take over the front end without a migration, although Lovable cannot adopt a repository you already have. Paid plans add custom domains with certificates issued automatically.
| Feature | Base44 | Lovable | Winner |
|---|---|---|---|
| Field-level permissionsBoth can hide a record from the wrong person. Only Base44 documents hiding a single column inside a record the person is otherwise allowed to read. | Row-level and field-level rules on entities | Database security policies | Base44 |
| Quality of the first visual draftLovable aims to be presentable before you touch it. Base44 expects you to tidy colour, type and spacing afterwards. | Generated UI, then a visual editor | Design-led generation from the prompt | Lovable |
| Start from a screenshot or specHand Lovable a mockup or a written specification and it builds from that. Base44 wants a description in words. | Not documented | Screenshots and documents accepted as input | Lovable |
| Sign-in for staff (SSO and SCIM)SCIM matters when leavers must lose access automatically rather than when somebody remembers. | OIDC via Okta or Entra ID, plus SCIM provisioning | Not documented for generated apps | Base44 |
| Business system connectorsIf the app has to read a warehouse table or post to a channel, Base44 starts with that built and Lovable starts with a blank function. | Slack, Google Workspace, Snowflake, Databricks, Resend | Written by you in Cloud edge functions | Base44 |
| Two-way GitHub syncLovable lets the repository become the source of truth from day one. Neither tool can import a repository that already exists. | Connect for version control and local work | Bidirectional on every plan, including free | Lovable |
| Managed backend includedBoth ship a first-party backend now. Comparisons that still say Lovable requires Supabase were written before Cloud shipped. | Entities, auth, functions, hosting | Lovable Cloud, on by default | Tie |
| Frontend stack choiceBase44 documents several template stacks. Lovable being React-only is simpler to reason about and harder to escape. | React via Vite, Vue, Solid, Refine, Hono, React Native | React | Base44 |
| AI provider for in-app featuresBundling is easier on day one. Your own account is easier to control, audit and renegotiate in year two. | Your own OpenAI, Claude, Groq or Mistral key | Bundled into Lovable Cloud | Base44 |
| Local development toolingBase44 ships local tooling as part of the product. Lovable expects GitHub to be your local story. | JavaScript SDK and a base44 dev CLI command | Clone the synced repository yourself | Base44 |
| Cost for a larger teamLovable prices by the credits a plan includes rather than per seat, and a workspace shares one pool, so headcount alone does not raise the bill. | Enterprise capability priced separately | Unlimited workspace members on every plan | Lovable |
| How the meter worksDifferent words, same structure: both charge you separately for building the app and for running it. | Message credits to build, integration credits at runtime | Build credits to build, Cloud credits at runtime | Tie |
| IndependenceWix ownership brings resources and distribution. It also puts roadmap decisions inside a public company whose main product is a website builder. | Owned by Wix since 2025 | Independent company | Lovable |
Both bill on two meters, which is the part most comparisons skip. Base44 draws message credits while you build and integration credits when the deployed app sends an email, generates an image or makes an AI call. Lovable draws build credits while you build and Cloud credits for what Lovable Cloud does. The build meter is what you notice in week one; the runtime meter is what you notice in month six, because on both platforms a successful app costs more to keep running than a quiet one. That is the opposite of how flat hosting behaves, and it is worth modelling before you commit rather than after. One structural difference does favour Lovable: it prices by included credits instead of per seat, and a workspace takes unlimited members on every plan sharing a single pool, so a ten-person team with modest usage pays what one person with the same usage pays. Base44 charges for enterprise identity capability rather than for headcount, which reverses the advantage once SSO and SCIM are requirements. Neither vendor has held its published rates steady, so check both pricing pages against your own expected traffic before deciding.
The comparison above is a choice between somebody else's permission model and somebody else's design system. Fabricate removes that framing by generating an ordinary codebase -- React with Vite, styled with Tailwind, behind a Hono API on Cloudflare Workers -- so the access rules are code you can read and the interface is markup you can edit. The honest cost of that is real: your access rules are now yours to get right, with no field-level toggle to lean on, and there is no screenshot-to-app path. If you want permissions handed to you, Base44 is the better tool; if you want the best-looking first draft, Lovable is.
