Why OpenLK

Sri Lanka generates vast amounts of public data — meteorological, infrastructural, demographic — but it rarely reaches the people who need it most. OpenLK exists to change that. We collect, clean, and publish open datasets so that researchers, developers, journalists and citizens can build on them freely.

Open Access
No paywalls. No accounts.
All data is public domain.
Machine Ready
CSV, JSON and API access
for every dataset.
Continuously Updated
Live feeds where possible.
Historical archives always.
