NicheDB watches public data that only ever grows, game releases, package registries, government filings, and turns it into feeds you can follow, subscribe to, query and script. Open source, one Postgres, and every row reachable by web, RSS, JSON, API, CLI and MCP.

NicheDB is an open-source platform that continuously monitors growing public datasets and turns them into structured feeds for querying, subscribing, and scripting.

The main features and capabilities of NicheDB include:

  • Universal Multi-Interface Access: Every data row is accessible keyless via Web, RSS, JSON, REST API, CLI, and MCP (Model Context Protocol) for direct integration with software scripts and AI agents.

  • Extensive Domain Collections: Ingests hundreds of thousands of daily items across diverse categories, including package releases (npm, PyPI, Crates.io), game launches, SEC EDGAR filings, weather advisories, FAA aviation delays, court dockets, and AI model pricing.

  • Single Database Engine: Built on a single PostgreSQL database architecture and published as open-source software under profullstack/niche-db.

  • Normalized & Deduplicated Schemas: Harmonizes disparate data sources—such as public procurement across different countries or MCP server listings from multiple community registries—into unified schemas and deduplicated records.

  • Free Access & Premium Tier: Offers keyless public feeds by default, alongside an optional Premium plan ($1.00/day) providing an ad-free experience, higher data limits, and additional account perks.

Module Bundling with Parcel

Module Bundling with Parcel

Parcel purports to be a “zero-config” alternative to Webpack, a popular Javascript module bundler. A module bundler takes separate, reusable JS files (or modules) and “bundles” them into a single file to be served to the browser, as well as minifying the output. This can improve website performance, as the browser doesn’t need to load a bunch of files individually. Post written by the author of "CSS in Real Life".
