Versions:
tilefeed is a lightweight PostGIS vector-tile pipeline developed by muimsd that keeps large-scale map datasets continuously synchronized with minimal overhead. Designed for production geospatial stacks, the utility listens to PostgreSQL’s native LISTEN/NOTIFY channel, intercepts every insert, update or delete that affects a spatial table, and instantly rewrites only the affected tiles inside an attached MBTiles archive. Because processing is incremental, a metropolitan region that receives hundreds of edits per minute can stay live on a public endpoint without the cost of re-seeding an entire pyramid. tilefeed accepts any SQL query that returns a geometry column, projects it to Web Mercator, clips and simplifies on the fly, then writes protobuf-encoded tiles that respect the Mapbox vector-tile specification. Version 0.6.1 refines concurrency handling, adds automatic tile compaction and exposes a Prometheus metrics port for observability; the two published releases (0.6.0 and 0.6.1) share the same wire protocol, so upgrades require only a binary swap. Typical deployments pair the tool with an Nginx tile cache in front, while background workers stream edits from an OSM diff or an internal auditing table; the result is a self-hosted alternative to commercial tile APIs that still serves low-latency maps to web, mobile or desktop clients. tilefeed is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
