DB Browser for SQLite
The DB Browser for SQLite
DB Browser for SQLite (DB4S) is a high quality, visual, open source tool to create, design, and edit database files compatible with SQLite. DB4S is for users and developers who want to create, search, and edit databases. DB4S uses a familiar spreadsheet-like interface, and complicated SQL commands do not have to be learned. This program is not a visual shell for the sqlite command line tool, and does not require familiarity with SQL commands. It is a tool to be used by both developers and end users, and must remain as simple to use as possible in order to achieve these goals. Import and export records as text, import and export tables from/to CSV files, import and export databases from/to SQL dump files, issue SQL queries and inspect the results, examine a log of all SQL commands issued by the application, plot simple graphs based on table or query data. -

Open ChatGPT Atlas
Open Source and Free Alternative to ChatGPT Atlas
Open ChatGPT Atlas is an open-source toolkit and interface for working with OpenAI’s ChatGPT models in a more extensible, adaptable, and composable way than standard web UIs allow. It provides an architecture where developers and power users can manage state, tool integrations, and multi-turn workflows with more control, enabling custom UIs, automation layers, and advanced routing logic. Unlike a fixed chat app, Atlas is designed as a foundation that can be extended with plugins, external APIs, and custom logic to support domain-specific assistants, agent-like behaviors, and multi-task workflows. The project includes utilities for session management to preserve context across interactions, structured interfaces for streaming responses, and integration layers that let you plug in third-party tools and services. It often forms the basis for research, prototyping, or production systems where the default ChatGPT interface isn’t flexible enough. -

uBlock
uBlock: a fast, lightweight, and lean blocker for Chrome, Firefox
uBlock: a fast, lightweight, and lean blocker for Chrome, Firefox, and Safari. Available on the Chrome Web Store or for manual installation. Available to install from the homepage. Available for install from the homepage or from the App Store. Available on the Firefox Add-ons site, or for manual installation. Opera shares Chrome's underlying engine, so you can install uBlock simply by grabbing the latest release for Chrome.To benefit from uBlock's higher efficiency, it's advised that you don't use other blockers at the same time (such as AdBlock or Adblock Plus). uBlock will do as well or better than most popular ad blockers. It's important to note that blocking ads is not theft. Don't fall for this creepy idea. The ultimate logical consequence of blocking = theft is the criminalisation of the inalienable right to privacy. -

Jev Ultrafast
A browser agent with a dynamic, indexed action space
Jev Ultrafast is an experimental browser agent built around a dynamic, indexed action space for fast web interaction. Each browser state is converted into a numbered table of currently available interactive elements. A policy chooses both an operation and a compatible target in a single network round trip. Supported actions include clicking, typing, selecting, scrolling, waiting, finishing, and reporting that a task is blocked. A small language model is invoked only when text must actually be generated for a typing action. The agent connects to Chrome through Browser Harness and provides an inspector showing elements, probabilities, decisions, and executed actions. Its design avoids site-specific scripts and instead relies on fresh observations of the live page. -

Telegraf
The plugin-driven server agent for collecting and reporting metrics
Telegraf is an agent for collecting, processing, aggregating, and writing metrics. Design goals are to have a minimal memory footprint with a plugin system so that developers in the community can easily add support for collecting metrics. Telegraf is plugin-driven and has the concept of 4 distinct plugin types. Input Plugins collect metrics from the system, services, or 3rd party APIs. Processor Plugins transform, decorate, and/or filter metrics. Aggregator Plugins create aggregate metrics (e.g. mean, min, max, quantiles, etc.). Output Plugins write metrics to various destinations. New plugins are designed to be easy to contribute, pull requests are welcomed and we work to incorporate as many pull requests as possible. You can try Telegraf right in your browser in the Telegraf playground. Telegraf shares the same minimum requirements as Go. -

Bits UI
The headless components for Svelte
Bits UI is an open-source headless component library designed specifically for the Svelte ecosystem, providing developers with flexible and accessible primitives for building custom user interface components. Instead of shipping with predefined styles, the library offers unstyled components that focus on behavior and accessibility, allowing developers to fully control the appearance of their UI through their own CSS or design systems. This headless architecture makes Bits UI particularly useful for teams that need reusable UI logic while maintaining consistent branding and visual customization. The project builds on concepts inspired by libraries such as Radix UI and React Spectrum and integrates builder patterns influenced by Melt UI to deliver powerful component abstractions. Developers can use Bits UI to implement complex interface patterns such as dropdowns, modals, and calendars while preserving accessibility standards and predictable interaction behaviors. -

Dev Browser
A Claude Skill to give your agent the ability to use a web browser
Dev Browser is a browser automation skill/plugin that enables an AI agent to control a real browser for verification and testing during development. Its purpose is to close the gap between “code was written” and “the UI actually works,” by letting the agent navigate, interact with pages, and validate behavior in a live environment. A key idea is persistence: the browser can keep pages open so the agent can navigate once and then perform multiple interactions across scripts without losing state each time. It supports flexible execution modes, allowing full-script runs when tasks are straightforward and step-by-step exploration when the agent needs to inspect or iterate carefully. To make automation more reliable for language models, it provides LLM-friendly DOM snapshots that structure the page in a way that is easier for an agent to interpret than raw HTML dumps. -

Reka UI
An open-source UI component library for building design systems
Reka UI is an open-source UI component library designed for building accessible and customizable web interfaces in Vue-based applications. The library provides a collection of unstyled UI primitives that developers can use as the foundation for creating fully customized design systems. Rather than forcing a predefined visual style, Reka UI focuses on accessibility, composability, and flexibility, allowing developers to implement their own visual themes and branding. The project evolved from the Radix Vue initiative and aims to bring the same accessibility-focused component patterns to the Vue ecosystem. By providing low-level building blocks instead of finished components, Reka UI allows developers to design complex interface elements while maintaining full control over styling and behavior. -

Sanity
Rapidly configure content workspaces powered by structured content
Sanity is an open-source real-time headless content management system that allows developers to manage structured content for websites, applications, and digital platforms. At the core of the system is Sanity Studio, a customizable editing environment built with React that can be configured to match the workflows and content models of different teams. Instead of using predefined content templates, Sanity allows developers to define schemas in code that determine how content is structured and stored. The platform stores data in a real-time backend called the Content Lake, enabling collaborative editing and instant updates across connected applications. Because the system separates content management from presentation, developers can use any front-end framework to display the data. Sanity also includes APIs and query tools that allow developers to retrieve content dynamically and integrate it into websites, mobile apps, and other digital services. -
