Free Log Analyzer | SpectX

SpectX is a powerful log analyzer for running queries on log files in local log servers and remote file storages. Download and install SpectX to your Desktop, point it at any text-based data in your filesystem, on-prem log servers, AWS S3 buckets, Azure, Hadoop or Google Storage. SpectX can also query Elastic clusters and JDBC-databases. The personal, Desktop edition can analyze unlimited volumes of data and is free.

Using SpectX, the raw data is your single source of truth. Instead of ingesting and capturing data into a vendor-locked format, SpectX creates a virtual table from the flat text files, giving you instant statistical insights and correlations without waiting for the data to ingest and index.
