24 alternatives to Datakit

DataKit started as my solution to Excel crashing on large files, but it's grown into a full browser-based data platform that handles CSV/Parquet/XLSXL/JSON files up to 20GB+ entirely client-side. What it does: Drag files → instant SQL querying (joins, aggregations, everything) Automatic data profiling (quality issues, null values, duplicates) Smart visualizations for every column type Export transformed/filtered results Now self-hostable: After requests from teams needing this behind firewalls, the entire platform can run on your infrastructure via…

    Hey HN! I'm open-sourcing DataKit today. GitHub: https://github.com/datakitpage/datakit Live demo: https://datakit.page DataKit is a browser-based data analysis platform that processes multi-gigabyte files (CSV, Parquet, JSON, Excel) entirely client-side using DuckDB-WASM. Your data never leaves your browser. What it does: • Process large files (tested up to 20GB) without any server • Full SQL interface powered by DuckDB compiled to WebAssembly • Python notebooks via Pyodide for data science workflows • Connect to remote sources (PostgreSQL, MotherDuck, S3) with…

    Hiya HN! TextQuery is my sabbatical project that I have been working on for the past six months. It was born out of a personal pain point. Anytime I wanted to analyze raw CSV data, I had to create a schema first before I could import it for querying. And to create charts, I had to use yet another tool. I also disliked how bad charts from popular tools like Excel, Google Sheets looked like. I wanted an easier way to do this and TextQuery was my solution: an all-in-one tool to query CSV files using SQL and create beautiful visualizations as well. Currently, it's a macOS app and focused on CSV…

    Hello HN, I'm excited to share a project I've been working on: A simple, fast way to process huge CSV and XLSX files directly in your browser and export them as clean JSON or XML Here's a few things that makes this converter different: - runs in the browser - all parsing and conversion is client side can handle data any size data - automatically detects delimiters, encodings, and data types as it parses - Live preview with column renaming, search/replace, and data cleanup - Export to JSON or XML — clean, structured output that can be used for API or Databases backstory: I built this…

    I built CSV GB+ by Data.olllo, a local data tool that lets you open, clean, and export gigabyte-sized CSVs (even billions of rows) without writing code. Most spreadsheet apps choke on big files. Coding in pandas or Polars works—but not everyone wants to write scripts just to filter or merge CSVs. CSV GB+ gives you a fast, point-and-click interface built on dual backends (memory-optimized or disk-backed) so you can process huge datasets offline. Key Features: Handles massive CSVs with ease — merge, split, dedup, filter, batch export Smart engine switch: disk-based "V Core" or RAM-based "P…

    Hi folks. I've been doing some experiments on how LLMs could get more handy in the day to day of working with files (CSV, Parquet, etc). Earlier last year, I built https://datakit.page and evolved it over and over into an all in-browser experience with help of duckdb-wasm. Got loads of feedbacks and I think it turned into a good shape with being an adhoc local data studio, but I kept hearing two main things/issues: Why can't the AI also change cells in the file we give to it? Why can't we modify this grid ourselves? So besides the whole READ and text-to-SQL flows, what seemed…

    In my previous role at a small startup, I frequently developed simple scripts to assist recruiters and marketing professionals in handling data processing tasks on Excel or CSV files. These tasks were typically straightforward and repetitive, stemming from the periodic export of data. This experience sparked the idea to create a straightforward tool dedicated to such functionalities(also mobile friendly, as they occasionally need to process data on their smartphones). There are powerful tools like Power Query and Tableau, but they often prove too complex for non-technical users to navigate…

Try it: https://local.dataspren.com (no account needed, runs locally) More information: https://github.com/dataspren-analytics/data-studio I love working with data (Postgres, SQL, DuckDB, DBT, Iceberg, ...). I always wanted a data exploration tool that runs in my browser and just works. Without any infra or privacy concerns (DuckDB UI came quite close). Features: - Data Notebooks - SQL cells work like DBT models (they materialize to views) -…

    I’ve been working on a side project for a while and wanted to share it with the HN community to get feedback. The idea started simple: I wanted to do batch image processing entirely in the browser without uploading anything to a server. Most existing tools were either cloud-based (privacy concerns, slow for large batches) or desktop apps that were hard to automate and combine into workflows. A big source of inspiration was macOS Automator. I really liked how you could chain small actions into repeatable workflows, and I wanted something similar for image processing on the web. At first it…
