Show HN: AgentLog – a lightweight event bus for AI agents using JSONL logs
Show HN (score: 6)Description
I built a small project called AgentLog.
The core idea is very simple, topics are just append-only JSONL files.
Agents publish events over HTTP and subscribe to streams using SSE.
The system is intentionally single-node and minimal for now.
Future ideas I’m exploring: - replayable agent workflows - tracing reasoning across agents - visualizing event timelines - distributed/federated agent logs
Curious if others building agent systems have run into similar needs.

Show HN: Life Tile – Passive time tracker that shows your day as a Mondrian grid
Show HN: Life Tile – Passive time tracker that shows your day as a Mondrian grid Hi, I developed Life Tile for iPhone. It tracks your time passively and visualizes it as a Mondrian-style grid. It's a one-time purchase app with a 7-day trial.<p>I was a user of a similar app named Life Cycle. Since the app hasn't been updated in a while, I tried to make a better app with my ideas and experiences. I used a big square timeline instead of a donut chart. And I added more useful views: tree-map, map, and list. You can use categorized activities with custom colors.<p>The data never leaves a device. No account, No Server. It only supports data backup using iCloud. It was for privacy but it also makes the development easier. I added just one anonymous usage stat with TelemetryDeck. You can turn it off anytime.<p>There were many technical difficulties. iOS location API (CLMonitor) is not 100% precise. And many difficult cases can't be handled automatically. For example, GPS blackout inside the subway, too many venues in a small region, and a huge location like an airport. So I improved many heuristics and tried my best for easy editing.<p>Please check the App Store for the screenshots. Then you'll know why it's inspired by Mondrian.
