November 2026 Summaries

Lovable has acquired the team behind Radish AI to strengthen its ability to support businesses building increasingly complex software and AI-driven operations on its platform. Radish AI developed infrastructure for building, deploying, and scaling AI agents with an emphasis on reliability, privacy, and security, and its founders bring engineering and AI leadership experience from companies including Meta, Google, Bloomberg, JPMorgan, and Goldman Sachs. The team will join Lovable’s engineering organization, with Nirman Gupta leading business-agent engineering from the company’s new London office, while members will work across London and Stockholm. Lovable says the acquisition will help customers automate business processes, operate more reliably, and scale software they build themselves, while the company continues hiring engineers.

Lovable replaced direct browser-to-Firestore subscriptions with Lovable Realtime, a Go-based WebSocket service that centralizes authorization, controls payload shaping, and continuously re-evaluates access as data or permissions change across Firestore and Spanner. The previous approach exposed entire Firestore documents to clients, required duplicated permission logic, and could not incorporate authorization data from systems such as Spanner efficiently at scale. The new service uses change data capture, NATS pub/sub, reactive data sources, cached snapshots, hash-based deduplication, and wire-level deltas to recompute only affected subscriptions and deliver updates efficiently through multiplexed WebSocket connections. After shadow testing and a gradual feature-flag rollout, the system reached more than 2 million concurrent subscriptions and delivered 2.61 billion frames in a month without user-facing incidents, while reducing estimated payload transfer by 97% compared with sending full snapshots for every update.
