EO Browser Alternative

A Free EO Browser Alternative

EO Browser has been retired. Off-Nadir Delta is a free, no-code, browser-based way to view and compare Sentinel and VIIRS imagery — and it goes further, letting you monitor any area over time.

Quick Answer: EO Browser, Sentinel Hub’s free imagery browser, was retired in March 2026. Off-Nadir Delta is a free, no-code, browser-based alternative for the core workflow — finding, visualizing, and comparing Sentinel-1, Sentinel-2, and VIIRS imagery — and it adds automated area monitoring and an event-intelligence layer that EO Browser did not have.

What to use instead of EO Browser

What EO Browser was great for

Quickly browsing and comparing full-resolution Sentinel and Landsat scenes in the browser, with ready-made visualizations and custom scripts for power users.

What Off-Nadir Delta adds

The same no-code browsing and visualization, plus automated area monitoring over time, change detection, active fires, and an event-intelligence layer (the Watchfloor) — all free to start.

Sentinel & VIIRS

View Sentinel-1 SAR, Sentinel-2 optical, and VIIRS nighttime lights — no account needed to start exploring.

One-Click Visualization

True Color, False Color, and indices like NDVI in a click — no band math, no scripting.

Monitor Over Time

Beyond a single scene: track an area as a time series with automatic anomaly detection.

Fast Search

Filter years of imagery by date and area and preview results before adding them to the map.

No Install

Runs entirely in the browser — nothing to download, just like EO Browser.

Event Intelligence

The Watchfloor overlays geolocated world events on imagery — a layer EO Browser never had.

How It Works

Open the map — no install

Off-Nadir Delta runs entirely in the browser, just like EO Browser. There is nothing to download and no GIS software to set up.

Search imagery by date and area

Pan to any location, filter by date, and preview Sentinel-1 SAR, Sentinel-2 optical, and VIIRS scenes before adding them to the map.

Visualize with one click

Switch between True Color, False Color, and spectral indices like NDVI instantly — no manual band math or scripts required.

Go beyond viewing — monitor over time

Draw an area and track how it changes as a time series with anomaly detection, and overlay real-world event signals on the Watchfloor.

Frequently Asked Questions

What happened to EO Browser?▼

EO Browser, the free satellite imagery browsing tool from Sentinel Hub, was retired in March 2026 as Sentinel Hub and Planet consolidated onto a unified platform. Many people who used EO Browser simply to view and compare Sentinel and Landsat imagery in the browser are now looking for a free, no-code replacement.

Is Off-Nadir Delta a good EO Browser alternative?▼

For the most common EO Browser workflow — opening a browser, finding recent satellite imagery over an area, switching visualizations, and comparing dates — yes. Off-Nadir Delta is browser-based and no-code, supports Sentinel-1 SAR, Sentinel-2 optical, and VIIRS, and offers one-click True Color, False Color, and index visualizations. It also adds capabilities EO Browser did not have: automated area monitoring over time and an event-intelligence layer.

Is it free?▼

Yes, you can start for free. Off-Nadir Delta uses token-based pricing for imagery rendering and processing, with a free tier to explore and view imagery. See the pricing page for current details.

Which satellites and data can I view?▼

Sentinel-1 C-band SAR (all-weather, day or night), Sentinel-2 optical (10m multispectral with True/False color and indices), VIIRS nighttime lights, and NASA FIRMS active fires. You can also upload your own GeoTIFF, COG, or GeoJSON files and overlay them.

Do I need an account or any installation?▼

No installation — it runs in the browser. You can browse the public Watchfloor and parts of the platform without an account; creating a free account unlocks saving your work and area monitoring.

I used EO Browser custom scripts (Evalscript). Can I do that here?▼

Off-Nadir Delta focuses on a fast, no-code experience with ready-made visualizations and indices rather than custom scripting. If your workflow depended heavily on custom Evalscripts, you may want a scripting-oriented platform; for everyday viewing, comparison, and monitoring, Off-Nadir Delta covers the core workflow without any code.

Switch From EO Browser in Minutes

View and compare satellite imagery free in your browser — then monitor any area over time. No install, no scripting.
