Build full-stack data analytics apps in Python

Datapane is an open-source framework for building robust, high-performance data apps from Python and Jupyter.

Why use Datapane?

🚀 Not just for demos

Build performant, robust full-stack apps which are simple to deploy and manage on any hosting platform. Add background processing, auth, and monitoring to go beyond MVPs.

📈 Share standalone reports with no server

Export static HTML reports which you can share on Slack or Email, with no backend required.

📙 Ship apps from Jupyter

Build and ship data apps from inside your Jupyter Notebook and existing scripts in <5 lines of code.

Other Features

• User sessions and state handling
• Intelligent caching
• Sub-5ms function response time
• Easy integration with authentication/authorization
• Integrate into existing web frameworks (like Flask or FastAPI)
• Host on existing web-hosts, like Fly and Heroku
• Background processing

How is Datapane's architecture unique?

Datapane Apps use a combination of pre-rendered frontend elements and backend Python functions which are called on-demand. Result: low-latency apps which are simple to build, host, and scale.

Installing Datapane

The best way to install Datapane is through pip or conda.

pip

$ pip3 install -U datapane

conda

$ conda install -c conda-forge "datapane>=0.15.6"

Datapane also works well in hosted Jupyter environments such as Colab or Binder, where you can install as follows:

!pip3 install --quiet datapane

Examples

📊 Share plots, data, and more as reports

Create reports from pandas DataFrames, plots from your favorite libraries, and text.

import altair as alt
from vega_datasets import data
import datapane as dp

df = data.iris()
fig = (
    alt.Chart(df)
    .mark_point()
    .encode(
        x="petalLength:Q",
        y="petalWidth:Q",
        color="species:N"
    )
)
view = dp.Blocks(
    dp.Plot(fig),
    dp.DataTable(df)
)
dp.save_report(view, path="my_app.html")

🎛 Layout using interactive blocks

Add dropdowns, selects, grid, pages, and 10+ other interactive blocks.

...

view = dp.Blocks(
    dp.Formula("x^2 + y^2 = z^2"),
    dp.Group(
        dp.BigNumber(
            heading="Number of percentage points",
            value="84%",
            change="2%",
            is_upward_change=True
        ),
        dp.BigNumber(
            heading="Simple Statistic", value=100
        ), columns=2
    ),
    dp.Select(
        dp.Plot(fig, label="Chart"),
        dp.DataTable(df, label="Data")
    ),
)
dp.save_report(view, path="layout_example.html")

Add functions to create full-stack apps

Add forms which run backend functions, or refresh your app automatically to build dashboards. Serve locally or deploy to your favorite web-host.

import altair as alt
from vega_datasets import data
import datapane as dp

df = data.iris()

def gen_assets(params):
    subset = df[df['species'] == params['species']]

    fig = alt.Chart(subset)
            .mark_point()
            .encode( x="petalLength:Q", y="petalWidth:Q")

    return [dp.Plot(fig), dp.DataTable(subset)]

view = dp.Form(
    on_submit=gen_assets,
    controls=dp.Controls(
      species=dp.Choice(options=list(df['species'].unique())
    )
)

dp.serve_app(view)

Analytics

By default, the Datapane Python library collects error reports and usage telemetry. This is used by us to help make the product better and to fix bugs. If you would like to disable this, simply create a file called no_analytics in your datapane config directory, e.g.

Linux

$ mkdir -p ~/.config/datapane && touch ~/.config/datapane/no_analytics

macOS

$ mkdir -p ~/Library/Application\ Support/datapane && touch ~/Library/Application\ Support/datapane/no_analytics

Windows (PowerShell)

PS> mkdir ~/AppData/Roaming/datapane -ea 0
PS> ni ~/AppData/Roaming/datapane/no_analytics -ea 0

You may need to try ~/AppData/Local instead of ~/AppData/Roaming on certain Windows configurations depending on the type of your user-account.
