I've been using elasticsearch-head [1] for four years now and it seems it has more features than dejavu? Specially the node/shard visualisation.
Fun fact: We actually started out with elasticsearch-head, but realized it was really hard to hack on (this was ~2y ago) and decided to create Dejavu. Imo, the key difference is we have focused a lot on how to get the data indexed (mappings, bring your CSV/JSON files) and have the raw data visualized (via UI based filters or DSL queries).
