Flightradar24 vs ADS-B Exchange: Which Flight Tracker for OSINT?
For commercial flight tracking, use Flightradar24. For tracking aircraft that have blocked themselves from filtered services, use ADS-B Exchange. Here's when each applies.
The only major flight tracker that refuses to filter opt-out aircraft
- +Does not honor FAA LADD opt-out requests — aircraft invisible on FR24 and FlightAware appear here
- +Manually curated 'Interesting Aircraft' list flags known government, law enforcement, and surveillance aircraft
- +MLAT support tracks aircraft without ADS-B transponders using time-difference-of-arrival from multiple receivers
- −UI noticeably rougher than Flightradar24 — functional, not polished
- −Coverage thins outside Europe and North America due to fewer volunteer receivers
- −Historical data beyond 7 days requires API arrangement with non-public pricing
Real-time and historical flight tracking via a global ADS-B receiver network
- +Best UI in the category — map is fast, clean, and works on mobile
- +365-day flight history on Gold tier ($7.99/mo) — enough for most investigative use
- +Aircraft detail pages include registration, operator, age, and sometimes owner
- −LADD opt-out aircraft don't appear — this is the single biggest gap for OSINT use
- −Military aircraft are frequently filtered or transmit false positions
- −Business API tier at $99.99/mo is priced for commercial operators, not investigators
For OSINT work, Flightradar24 and ADS-B Exchange serve different needs, due to LADD opt-outs.
Flightradar24 respects LADD. If a private jet operator opts out, their tail number disappears from FR24's map. The aircraft still flies, its transponder still broadcasts, but you won't see it.
ADS-B Exchange doesn't honor LADD. If a transponder transmits, the aircraft shows on the map. This makes ADSBExchange ideal for tracking high-profile private jets, government surveillance aircraft.
The difference matters. For investigative tracking, ADSBExchange is the only option. FR24 excels elsewhere, covering 100 million monthly commercial flights, with satellite AIS filling oceanic and remote routes.
FR24's UI is clean, with functional mobile apps and useful flight detail pages. Historical data is available for $7.99/month.
ADSBExchange offers more for private jets, with an "Interesting Aircraft" filter and MLAT coverage for non-ADS-B aircraft. Data is free and unfiltered.
When to use each? Use FR24 for tracking commercial airlines and airport activity. Use ADSBExchange for private jets and government planes. Using both allows for cross-validation.
Here's a breakdown of the key features:
| Flightradar24 | ADS-B Exchange | |
|---|---|---|
| LADD filtering | Yes | No |
| Primary data source | ADS-B + MLAT + satellite | ADS-B + MLAT |
| Web map (free) | Yes (limited) | Yes (full access) |
| Mobile app | Yes (iOS/Android) | Limited |
| Historical data | 365 days (Gold tier) | Limited on free tier |
| API access | Yes (Business tier, expensive) | Yes (pricing on request) |
| "Interesting Aircraft" filter | No | Yes |
| Satellite AIS (marine) | Yes | No |
| MLAT coverage | Yes | Yes (strong volunteer network) |
| UI polish | High | Functional, not polished |
| Monthly active users | 100M+ | Smaller, enthusiast-heavy |
| Coverage gaps | Minimal globally | Some thin regions (fewer receivers) |
FR24's free tier gets you started. Paid plans are Silver ($2.99/month), Gold ($7.99/month), and custom Business rates.
ADSBExchange's web map is free; API pricing is available upon request.
FR24 handles commercial aviation and casual flight tracking. ADSBExchange is used for more in-depth tracking, when a target might be hiding. Use FR24 for general tracking; switch to ADSBExchange if LADD blocking is possible.
