Data Docked is an Estonia-based maritime data API platform providing real-time and historical vessel tracking powered by satellite and terrestrial AIS (Automatic Identification System) technology. The service monitors over 830,000 vessels globally with a REST API offering 16 endpoints. Core capabilities include real-time vessel positions (latitude, longitude, speed, course, heading, ETA), comprehensive vessel specifications (dimensions, tonnage, build year, engine details), port activity analytics, and up to two years of historical voyage data.

The platform also integrates port state control inspection records across 9 international memorandums of understanding (MOUs) plus USCG data, serving maritime professionals across fleet operations, supply chain optimization, commodity trading, insurance underwriting, compliance, and shipbroking. The service commits to 99.9% uptime and combines terrestrial AIS (for coastal coverage) with satellite AIS (for global ocean coverage) in a single unified API, contrasting with competitors that often rely on one source. Following market consolidation—notably Kpler's acquisition of MarineTraffic, FleetMon, and Spire Maritime by April 2025—Data Docked has positioned itself as a developer-friendly alternative with transparent, credit-based pricing and self-serve signup, targeting teams seeking predictable costs and API flexibility rather than enterprise-only sales models.

How it works

  1. Real-time vessel positions

    Latitude, longitude, speed over ground, course, heading, and estimated time of arrival (ETA) for tracked vessels.

  2. Vessel particulars database

    Ship specifications including dimensions, gross tonnage, build year, engine type, IMO number, and flag state.

  3. Port call analytics

    Historical port activity, traffic patterns, and route optimization with distance calculations.

  4. PSC and sanctions data

    Port state control inspection records across 9 international MOUs and USCG compliance data.

  5. Historical voyage data

    Two-year lookback on vessel movements, routes, and port calls for analytical queries.

  6. Developer-friendly REST API

    16 endpoints with SDKs for Python, JavaScript, and other languages; JSON and CSV export options.

  7. Pre-built maritime applications

    Ready-to-deploy tools including Sea Trace vessel tracking, Port Analytics dashboards, and Route Planning utilities.

Strengths and trade-offs

Strengths

  • Transparent credit-based pricing from €80/month with no enterprise gatekeeping; lowest entry cost among major AIS providers.
  • Combined satellite + terrestrial AIS coverage in one API, avoiding single-source latency or coverage gaps.
  • Developer experience prioritized: self-serve signup, 20 free credits, SDKs, clear documentation, and sub-12-hour support response times.

Trade-offs

  • Limited usage visibility: single G2 reviewer (5.0 star) requested dashboard analytics for API request tracking and credit consumption—a gap relative to competitors.
  • Smaller installed base: 320+ customers is a fraction of legacy incumbents; less community content, fewer Stack Overflow discussions, and less third-party integration coverage.
  • Early-stage product maturity: minimal independent review volume (1 G2 review, limited Reddit/HN discussion) compared to MarineTraffic or VesselFinder, raising questions about long-term platform stability and roadmap prioritization.

Pricing context

Data Docked uses a credit-based model with transparent, self-serve pricing starting at €80/month. New users receive 20 free credits to test the platform. Individual API calls cost 1–50 credits depending on the endpoint (position queries cost fewer credits than historical or enriched data).

Bulk and historical queries use higher credit allocations. The service specifically markets transparent, predictable pricing as a differentiation point against MarineTraffic, which removed credit-based tiers in January 2025 and shifted to enterprise-only sales. No monthly contract lock-in is mentioned; pricing is consumption-based and billed as credits are used.
