Klogg is cross-platform open source tool designed to view and search information in large log files.

Klogg:

  • Runs on Unix-like systems, Windows and Mac thanks to Qt5
  • Supports Perl-compatible regular expressions
  • Is fast and reads the file directly from disk, without loading it into memory
  • Utilizes all CPU cores to speed up regex-matching
  • Detects file encoding using uchardet library (support utf8, utf16, cp1251 and more)
  • Colorizes the log and search results
  • Watches for file changes on disk and reloads it (kind of like tail)

CSVFiddle features and specs

  • Browser-based convenience
    CSVFiddle runs entirely in the browser, allowing users to quickly test and manipulate CSV data using SQL queries without installing any software or setting up a database.
  • SQL querying on CSV data
    It allows users to run SQL queries directly on CSV files, which is helpful for those familiar with SQL who want to filter, join, or transform tabular data without needing a full database system.
  • Quick prototyping and sharing
    The tool is useful for quickly prototyping data transformations and sharing results or queries with others, similar to how JSFiddle works for code snippets.
  • No installation required
    Since it's a web-based tool, there is no need to install any database software, drivers, or dependencies, making it accessible from any device with a browser.
  • Good for learning SQL
    CSVFiddle can serve as a lightweight sandbox for practicing SQL syntax and queries on custom datasets without the overhead of setting up a full database environment.

Possible disadvantages of CSVFiddle

  • Limited scalability
    As a browser-based tool, CSVFiddle is likely not designed to handle very large CSV files or complex datasets efficiently, making it unsuitable for big data tasks.
  • Feature limitations compared to full databases
    Since it's a lightweight tool focused on CSV and SQL, it may lack advanced features found in full-fledged database management systems, such as indexing, stored procedures, or advanced transaction support.
  • Dependency on internet connectivity
    Being a web-based application, it requires an internet connection to function, which can be a limitation for users who need offline access to their data tools.
  • Potential data privacy concerns
    Uploading CSV data to a third-party web service may raise concerns about data privacy and security, especially for sensitive or proprietary datasets.
  • Limited export/import options
    The tool may have restricted capabilities for exporting results or importing complex data formats compared to more robust data analysis platforms.

Analysis of CSVFiddle

Overall verdict

  • CSVFiddle appears to be a useful lightweight, browser-based tool for quickly viewing, querying, and manipulating CSV files without installing software, making it convenient for fast data checks and simple transformations, though it's not a replacement for full-featured data analysis platforms when handling very large datasets or complex workflows.

Why this product is good

  • Runs directly in the browser, so no installation or setup is required
  • Allows quick querying and filtering of CSV data, often using SQL-like syntax
  • Useful for fast, one-off data inspection and lightweight transformations
  • Free or low-cost accessibility makes it attractive for casual or occasional use
  • Simple interface that lowers the learning curve compared to full BI or spreadsheet tools

Recommended for

  • Developers or analysts who need to quickly inspect or query CSV files
  • Users who prefer browser-based tools over installing desktop software
  • People doing lightweight data cleaning or filtering tasks
  • Students or hobbyists working with small to medium-sized datasets
  • Anyone needing a fast, no-frills alternative to spreadsheet programs for CSV review

  • How to process 100gb tsv and XML files?
    I found this https://klogg.filimonov.dev. - Source: Hacker News / almost 2 years ago
  • Lnav Logfile Navigator
    Not a CLI tool, but I recently started using https://klogg.filimonov.dev/ klogg (which seems to be a successor of glogg) more and more often. - Source: Hacker News / about 2 years ago
  • Share your greatest free tools
    Glogg is a great tool, but unfortunately it is not developed anymore. I maintain a fork -- klogg (https://klogg.filimonov.dev). It is generally faster for both opening a file and performing searches. Current dev builds that use hyperscan regular expression engine can open a file and do a search while glogg would still be indexing that file. Source: about 4 years ago
  • Opening large files (>2GB) in Windows
    Once I had to go through an unusually large log file which was around 2GB. I am a regular Notepad++ user but it couldn't handle the file. In addition to opening the file I also needed to search around the file for keywords like Error or Exception. I found klogg to be just the right tool for me. It allows for viewing as well searching for words within the large text file easily. - Source: dev.to / over 4 years ago
  • pyTermTk, a personal attempt to create a Python TUI
    This is still an early stage TUI, many widgets are incomplete or missing (i.e. Text area, partial keyboard support, incomprehensible Documentation) I have very little time to work on it and the progresses are incredibly slow. I develop it in order to create a terminal log viewer that could mimic the features exposed by glogg or klogg. Source: over 4 years ago
