Velocity - a self-hosted flight and ship tracker that keeps its own history

Flightradar24 now charges for anything older than 12 hours, and I wanted my own copy. So I built Velocity: a docker compose stack that tracks live aircraft and ships from public ADS-B and AIS feeds (no API keys), records every position it sees to your own disk, and lets you scrub the map back to any moment. Mine has about 132M positions since August. Other bits: if you run your own ADS-B receiver, point it at your tar1090 and it folds that in area alerts to Discord, a webhook or ntfy

痛点：Flightradar24 把 12 小时以上的历史航班数据改成付费，用户想要自己拥有、可长期回溯的航班/船舶轨迹历史。

目标用户：航空/航运爱好者、OSINT 与记者、需要历史轨迹取证或做个人数据留存的自托管玩家

证据：Flightradar24 now charges for anything older than 12 hours, and I wanted my own copy. ... Mine has about 132M positions since August.

变现：开源核心 + 托管版订阅（帮你跑 docker、长期存储与回放、区域告警），或按区域/时间查询的历史轨迹 API 计费

MVP：两周内做一个单一区域的轨迹归档服务：订阅公开 ADS-B/AIS 源，把位置写入 SQLite/TimescaleDB，提供时间轴回放网页 + 简单查询 API 与 Discord/ntfy 区域告警

竞品：Flightradar24、ADS-B Exchange、tar1090 / readsb、MarineTraffic、airplanes.live

摘要：作者因 Flightradar24 对 12 小时以上历史数据收费，自建了开源项目 Velocity，用公开 ADS-B/AIS 源无 API key 采集并落盘，8 月以来已存约 1.32 亿个位置点，支持地图回放、区域告警和 MCP 接口。项目采用 AGPL 免费开源，但暴露出一个仍在被商业化收取费用的需求：自持历史轨迹数据。
