FastTree infers approximately-maximum-likelihood phylogenetic trees from alignments of nucleotide or protein sequences. FastTree can handle alignments with up to a million of sequences in a reasonable amount of time and memory. For large alignments, FastTree is 100-1,000 times faster than PhyML 3.0 or RAxML 7

If you publish research that uses fasttree you have to cite it as follows:

The following papers describe FastTree. The first paper describes FastTree 1.0, and the second paper describes heuristic minimum-evolution SPR moves, maximum-likelihood NNIs, and SH-like local supports. We have also eliminated the O(N2) steps in the neighbor-joining phase, and implemented maximum-likelihood NNI moves and SH-like supports (see the ChangeLog).
