# Web application

Our web app will allow you to explore UniChem database information and perform useful searches on it, such as:

1. [Compound Sources searches ](/unichem/web-application/compound-sources-search.md)
2. [Compound connectivity](/unichem/web-application/connectivity-search.md)
3. [Similarity search](/unichem/web-application/similarity-search.md)
4. Sources to where our data is linked from

Compound searches both supports ID on the source database, InChI, InChI key and UniChEM Identifier (UCI) searches, as well as drawing your compound.
