Lovable replaces Firestore frontend links with its own realtime service

Lovable says it has replaced frontend dependencies on Firestore with Lovable Realtime, a WebSocket service built in Go and backed by NATS. The change gives the company more central control over permissions and data sent to connected apps, an important bit of plumbing for an AI coding platform where “it works” is only the beginning.

What happened

In a post published on 9 November, Lovable describes building a dedicated service to manage live updates between its backend and frontends. It uses change data capture to track changes, then shapes data on the server and uses hash-based deduplication to avoid sending unnecessary repeats. Lovable says the architecture is designed to support millions of concurrent subscriptions while reducing payload volumes.

The company says the migration was completed without user-facing incidents. Its stated reasons for moving away from frontend Firestore dependencies include improving authorisation controls and managing permissions centrally. The details are in Lovable’s account of its realtime service.

Why it matters

Realtime infrastructure is easy to overlook until permissions, load or a flood of redundant updates become the problem. Moving those decisions server-side gives Lovable a more direct way to shape what connected apps receive, while the deduplication approach is intended to cut unnecessary traffic. That matters for a product built around turning prompts into working software: the service behind the interface has to keep up, too.

The scale figure is a design target, not a performance result reported here. Still, replacing a frontend dependency with infrastructure Lovable controls is a consequential engineering choice, not just a fresh coat of framework paint.

Our read

This is a practical infrastructure story with a clear payoff: more central control over authorisation and updates, and less reliance on a frontend connection to Firestore. The interesting test now is whether the service handles real growth as neatly as its architecture promises. “Millions of subscriptions” is a fine ambition; production traffic is where the architecture gets to meet its relatives.

What to watch

• Whether Lovable shares measured performance or scale results from production.
• How the service changes authorisation and data delivery for Lovable-built apps.
• Whether Lovable reports any user-facing trade-offs as the migration beds in.

Discussion spark: When a product depends on live updates, should teams favour infrastructure they control themselves or established services such as Firestore?
