Most geospatial platforms look similar at first glance — a map, a search bar, some satellite tiles. But look closer, and different approaches emerge: some built around a deep optical archive with analytical tools ready to use, and others aiming to funnel commercial sensors of every kind into whatever system you already run.

Your choice comes down to what your team actually needs. We break down LandViewer and SkyFi so you can match your workflow to either a self-contained platform for tracking land over time with free and high-resolution satellite imagery, or a procurement hub for sourcing raw commercial data from dozens of providers.

LandViewer – Workhorse For In-Depth Satellite Insights 

If you need to find, view, and work with satellite images without wrestling with massive GIS software, you open LandViewer. It lives entirely in your browser and skips the usual step of downloading gigabytes of files just to see a single field. You drop your coordinates on the map and start extracting data right away.

Here's what you can actually do with LandViewer:

  • Access over 40 years of imagery. Free Landsat, Sentinel-2, and MODIS coverage worldwide, updated daily, with an archive dating back to 1982.
  • Get answers instead of formulas. Over 20 spectral indices, such as NDVI and NBR, plus a custom builder for your own band combinations.
  • Spot changes on the ground instantly. Overlaying two images from different dates surfaces vegetation loss, flooding, or new development at a glance.
  • Get fresh imagery on demand. For projects requiring extreme detail, task any of eight high-res satellites (including BJ3N, SuperView NEO-1, BlackSky Gen-3, and KOMPSAT‑3A) to capture custom imagery down to 0.3-meter resolution. 
  • Start without spending. Up to 15 free medium-resolution images available every month.
  • Skip the learning curve. An interface built for first-time users of satellite data, not just experts.

What to keep in mind: LandViewer's core strength is multispectral optical imagery. SAR and hyperspectral imagery can be ordered separately, but these aren't the platform's main focus. 

SkyFi – Marketplace For Diverse Satellite Data

SkyFi takes a different route. Instead of running its own archive, it works as a marketplace that pools over 150 satellites from over 50 commercial operators into one account with one ordering process and one pricing structure. It features:

  • A large pool of operators. Vantor, Planet Labs, ICEYE, Umbra, and Satellogic are among the partners available through SkyFi.
  • Multiple data formats. Optical, multispectral, SAR, hyperspectral, thermal, and aerial imagery can be ordered the same way.
  • High-res imagery options. By partnering with commercial operators, the marketplace provides imagery down to sub-decimeter detail.
  • Surface-level analytical tools. You get a minimal set of built-in features with little or no customization.
  • API for larger workflows. Supports monitoring pipelines and links to GIS or BI systems.

What to keep in mind: SkyFi's strength is breadth, not depth. Its analytics cover common tasks like object detection and change visualization, but don't go as far as dedicated vegetation indices or long-term time-series tracking.

When To Choose LandViewer

LandViewer fits best when you're watching one area over time and need indices with a track record behind them, not just imagery. If your work is optical-based and depends on consistent, comparable data across months or years, this is where it performs strongest:

  • Agriculture and land management. Tracking crop health season after season through NDVI and common vegetation indices applied to high-res satellite images.
  • Environmental tracking. Monitoring clear-cutting, shoreline changes, fire scars, or spreading desertification across decades.
  • Research and education. Free access to 40+ years of high-quality satellite images, updated daily, gives students and researchers plenty to work with.
  • Tight budgets. Many pilot studies and small-scale projects can run entirely on the free tier, which removes cost as a barrier from the start.

In each case, the value is in seeing the same place again and again, long enough to notice what actually changed. On top of that, LandViewer's built-in indices and analytical tools help point to what matters most.

When To Choose SkyFi

SkyFi fits best when one sensor type isn't enough, and you need to pull from many satellites, resolutions, and data types in a single order:

  • Defense and security. Missions here can't wait for clear skies — SAR sees through clouds and in the darkness, and the ATAK plugin puts that imagery straight in front of operators already in the field.
  • Finance and insurance. Fast tasking shows what's happening at ports, warehouses, or disaster-affected sites right away.
  • Multi-source projects. Comparing optical against SAR, or different resolutions, without switching platforms.
  • Automated monitoring. The API supports alerts triggered by detected change.

While it lacks LandViewer's out-of-the-box analytical tools, the sheer variety of data formats makes it a practical option for purchasing raw high-resolution images of Earth.

The Verdict

LandViewer and SkyFi are complementary tools rather than direct rivals. The choice simply depends on what your team needs to accomplish:

  • Choose LandViewer if you need a cost-effective, browser-based laboratory to monitor vegetation, track historical land changes, and analyze environmental data over time using built-in scientific indices.
  • Choose SkyFi if you need an aggregated commercial storefront to buy varied sensors, integrate custom data feeds via an API, or order ultra-high-resolution satellite images from multiple operators simultaneously.

So, whether you want a deep browser laboratory or an expansive marketplace, getting the highest-quality satellite imagery is just a few clicks away.
