Where Lovable is the better fit
If the deliverable is a public-facing web app or a website, Lovable is built around that outcome. Its own product page describes hosting, SSL, backend infrastructure, payments, and security scans as part of the platform.
That means less assembly for a launch: the deployment and the public surface are part of the product. For a marketing site, a customer portal, or a paid web app, start there.
Where Sigla is the better fit
If the deliverable is a small internal tool that one team uses every day, the questions are different: where the files live, who operates the tool, and how it changes. Sigla runs on the desktop, reads local files, and keeps the workspace on your machine.
The second difference is operation. In Sigla, the agent can read and use the same app it built, so routine work can be handed over without a person clicking through every screen. That matters for research, reporting, and ops tasks that repeat.
Can you use both?
Yes, and many teams should. Use Lovable for the public surface and Sigla for the internal work behind it. The boundary to agree on early is which system holds the source of truth.
If the two tools both edit the same data, decide the owner before the second tool exists. A shared source of truth prevents the reconciliation work that makes small tools expensive.
How to decide in ten minutes
Write three answers: where the result has to run, who operates it after week one, and what changes most often. If the answer to all three is "in a browser, by customers, the marketing copy", choose the hosted builder.
If the answers are "on my machine, by me and an agent, the workflow", choose the desktop workspace. Then check the price model against how often you expect to rebuild.

FAQ
Is Sigla a Lovable replacement?
Not in general. It is a different shape: a desktop workspace for internal work rather than a hosted builder for public apps. For some internal tools it replaces the need; for public apps it does not.
Which is better for a public web app?
The hosted builder, if the app has to be public, handle payments, and live on the web. That is the job Lovable describes on its own site.
Which is better for internal tools?
The desktop workspace, when the tool reads local files, runs long tasks, and is operated by the same person who asked for it.
Can I move work from one to the other?
Not automatically. Treat the first build as a prototype: agree the data model, then rebuild where the work has to live. Moving a UI is easier than moving a data model.
