MG-RAST review
A free, specialist service for processing and comparing metagenomic sequence data.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MG-RAST is a web-based service for researchers analyzing metagenomic sequence data, including shotgun metagenomes, metatranscriptomes, and ribosomal amplicon data. Users can upload sequence files for automated processing, then explore and compare results in the web interface. It is designed for scientific sequence analysis, not business reporting or broad analytics workflows, so its fit depends on the data and research task.
The workflow covers quality control and normalization, taxonomic and functional annotation, and comparison of multiple metagenome datasets. Researchers can also explore metadata, discover datasets, download sequence data and analysis results, and create and share projects through the web interface. Programmatic access is available through a REST API. Documented file formats include FASTA, FASTQ, and SFF, making the service relevant to researchers with these sequence inputs; it is not a general-purpose environment for arbitrary data sources.
MG-RAST is free, and the published product details identify it as open source. The service is cloud-based, with web and API access; documentation is the listed support channel. Choose it if your work centers on supported metagenomic sequence data and you need processing, annotation, comparison, or data discovery in one specialized service. Researchers seeking broad business analytics, or teams that need a wider set of support channels or data workflows, should look elsewhere. Its specialization is the main reason to consider it—and the main constraint for buyers outside metagenomics.
