Questions we keep getting
What's the difference between MarineTraffic and Similarweb?
MarineTraffic leans toward data visualizations, APIs & data feeds, and shipping & trade, while Similarweb puts more weight on app & website traffic, APIs & data feeds, and sheets / excel add-ins. They overlap in 2 categories, so for most people it comes down to workflow preference and price.
How much do MarineTraffic and Similarweb cost?
Good news: both MarineTraffic and Similarweb have free plans, so you can run them side by side and only pay if you hit a wall.
Can I use MarineTraffic or Similarweb on my phone?
MarineTraffic lists a dedicated mobile app, so it travels better. Similarweb doesn't list a dedicated mobile app; its documented access is web and API.
Do MarineTraffic and Similarweb have APIs?
Yes, both offer API access, so developers and quants can pull data programmatically or wire up their own integrations.
Should I choose MarineTraffic or Similarweb?
It depends on what you're after. Pick MarineTraffic if shipping & trade and alerts matter to you; go with Similarweb if you'd rather have app & website traffic and sheets / excel add-ins. And if you only need the basics both share, let price decide.

MarineTraffic offers real-time data, which matters if you trade actively. Similarweb runs on delayed or end-of-day data, which is perfectly fine for longer-term investors who don't live and die by the tick.

Curation & Accuracy
This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).
Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
