An IDX site on a RESO Web API feed: what the docs leave out

The RESO Web API standard guarantees a small floor: paged results, an explicit field list, and a link to the next page to follow, and nothing more. Everything above that floor is your MLS's choice, and almost none of it is written down. Build notes from a feed integration that went live in August 2026.

28,000 listings on one map with MapLibre and no API bill

Every active listing in the state lands on one map, drawn by MapLibre GL JS on ordinary shared hosting, with nothing metering the page loads. One version-stamped GeoJSON off the sync cron feeds the pins, and a self-hosted PMTiles archive is measured and staged to answer for the basemap the free hosted style is drawing today.

When an image pipeline fails silently: a disk-quota postmortem

A listing page said "48 photos" above a grid of blank tiles, and every layer underneath it, from encoder to cache to queue, had reported success.

Grace Tarnasky messaged me on a Thursday and had a working site on Saturday. A walkthrough and a look at the decisions: why her listings are real pages instead of an IDX iframe, why six neighbourhood guides matter more than a search box, and what a fork of an engine buys you.

How a real estate agent gets recommended by an AI assistant

Buyers have started asking ChatGPT to recommend an agent. That answer is assembled from sources a machine can verify, which is a different game from ranking, and a more winnable one.

Real estate runs on too many dashboards

Every realtor I've worked with pays for five systems that don't talk to each other. The fix isn't another integration. It's one system that owns the whole flow, from listing to lead to closed.
