fr24

fr24 is a Python library for data retrieval from Flightradar24 using gRPC and JSON APIs.

For a detailed quickstart, examples and references, please refer to the documentation.

Features

fr24 supports the following endpoints:

fr24 is built with modularity and performance in mind, utilising asynchronous programming to handle concurrent requests efficiently.

Installation

For the latest stable version:

pip install 'fr24[curl]'
pip install 'fr24[httpx]'

[!IMPORTANT] fr24 does not come with a HTTP client library by default. You must pick one:

• fr24[curl]: curl client (recommended), supports gRPC and JSON
• fr24[httpx]: HTTPX client, supports gRPC only

If you need to_polars(), write_table(), scan_table(), or CSV/Parquet (de)serialisation, install fr24[polars].

Other feature flags:

• fr24[polars]: dataframe and table I/O support via Polars
• fr24[cli]: command-line interface dependencies, including polars and rich
• fr24[tui]: terminal UI dependencies, including cli

For a development version, clone the repository and run in the directory:

uv venv
source .venv/bin/activate
uv sync --all-extras --dev

This installs all optional dependencies, typing, linting, testing and documentation tools.

Examples

Fetch live feed data for a specific bounding box:

import asyncio

from fr24 import FR24, BoundingBox

bbox = BoundingBox(south=42, north=52, west=-8, east=10)


async def main() -> None:
    async with FR24() as client:
        result = await client.live_feed.fetch(bbox)
        print(result.response.content)  # access raw, undecoded bytes
        # convert to other formats:
        print(result.to_proto())  # protobuf object
        print(result.to_dict())  # nested dictionary
        print(result.to_polars())  # polars dataframe

        # write to a parquet file:
        result.write_table("feed.parquet")


if __name__ == "__main__":
    asyncio.run(main())

To improve efficiency and reduce API calls, fr24 provides a simple file-based cache:

import asyncio

from fr24 import FR24, FR24Cache, BBOX_FRANCE_UIR

cache = FR24Cache.default()


async def main() -> None:
    async with FR24() as client:
        result = await client.live_feed.fetch(BBOX_FRANCE_UIR)
        # on Linux, this writes to ~/.cache/fr24/feed/{timestamp_s}.parquet
        result.write_table(cache)


def some_time_later() -> None:
    for fp in cache.live_feed.glob("*"):
        print(fp)
        print(cache.live_feed.scan_table(fp).collect())


if __name__ == "__main__":
    asyncio.run(main())
    some_time_later()

fr24 also comes with a CLI for quick data retrieval:
