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. -

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. -

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. -

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. -

Flutter Workmanager
A Flutter plugin which allows you to execute code in the background
Flutter Workmanager is an open-source Flutter plugin that enables developers to execute Dart code in the background on both Android and iOS devices, even when the application is not actively running. It acts as a wrapper around native background task systems such as Android’s WorkManager and iOS background execution APIs, providing a unified interface for scheduling and managing tasks across platforms. The plugin is designed to handle asynchronous operations that need to run independently of the app’s lifecycle, such as syncing data, uploading files, fetching notifications, or performing maintenance tasks. It supports both one-off tasks and periodic tasks, allowing developers to configure execution frequency and constraints such as network availability or device state. -

Pinchtab
High-performance browser automation bridge and orchestrator
Pinchtab is a lightweight browser automation backend built specifically for AI agents that need efficient, programmatic web control. Implemented as a small standalone HTTP server, it allows any agent or script to interact with web pages using simple API calls instead of heavyweight browser frameworks. The tool emphasizes accessibility-first snapshots that dramatically reduce token usage compared to screenshot-based approaches, making it cost-effective for large-scale automation. It launches and manages its own Chrome instance while remaining framework-agnostic, so it can be used with any language or agent system. Pinchtab also supports persistent sessions, stealth automation, and both headless and headed operation modes. The project’s goal is to provide fast, cheap, and portable browser control infrastructure for modern AI workflows. -

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. -

Browserless
Deploy headless browsers in Docker
Browserless is an open-source browser automation platform for running headless browsers in Docker or through Browserless-hosted cloud infrastructure. It lets developers connect existing Puppeteer and Playwright code to remote browser sessions over WebSocket, which helps move heavy browser work away from local machines or application servers. The project also provides REST APIs for common automation tasks such as screenshots, PDF generation, scraping, crawling, and content export. Browserless is useful for teams that need scalable browser execution for testing, data collection, rendering, or AI-agent browsing workflows. Its deployment model supports self-hosting, private infrastructure, queues, concurrency controls, and enterprise-oriented configuration. The project’s main value is turning browser automation into a managed service layer that can be reused across applications and workflows. -

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. -
