Figmentor

Figmentor is a plugin-powered platform that converts designs from Figma into fully importable Elementor JSON templates with pixel-perfect accuracy, all in a single click. Users start by selecting their Figma frame, then FIGMENTOR generates a clean, optimized Elementor-compatible output that preserves layout, typography, and spacing and supports responsive design. The export fully supports widgets like columns, images, buttons, and text layers, while maintaining the original Figma layer structure for easy post-import edits. SEO-optimized markup and clean structure ensure strong search engine visibility from the start. Compatible with both free and Pro versions of Elementor, the platform streamlines the handoff between design and development, eliminating hours of manual coding, reducing revision cycles, and enabling faster site delivery. Designed for a designer-first workflow, Figmentor works through a Figma plugin and a WordPress/Elementor plugin to cover the full conversion journey.

GrowthBook

GrowthBook is an open source feature-flagging and experimentation platform built to help teams release code confidently and measure the impact of product changes using their own data. It enables the creation and management of feature flags of various types (Boolean, number, string, JSON) with targeting rules, percentage roll-outs, safe ramp-ups, and experiment assignment. The platform is warehouse-native, allowing you to connect your data where it already lives (SQL data warehouses, Mixpanel, Google Analytics, and more) and run experiments and analyses without sending raw user-level PII to a third-party service. It supports modular usage; you can adopt just feature flagging, just experiment analysis, or both together. Key capabilities include: high-performance lightweight SDKs (enabling billions of feature lookups per day), a visual editor for no-code AB tests, and experiment reporting with advanced statistical methods.

WunderGraph Cosmo

WunderGraph

WunderGraph is an open source, next-generation API platform designed to unify, manage, and accelerate how developers compose, integrate, and serve APIs from diverse backends (such as REST, gRPC, Kafka, and GraphQL) into a single, type-safe, high-performance API surface that modern applications can consume. It includes Cosmo, a full lifecycle API management solution for federated GraphQL that provides schema registry, composition checks, routing, analytics, metrics, tracing, and observability, all manageable via code in your existing development workflows rather than separate dashboards. WunderGraph lets teams define how multiple services should be composed into one API, automatically generate type-safe client libraries, and handle authentication, authorization, and API calls with built-in tooling that fits into CI/CD and Git-centric processes.

OpenGraph

OpenGraph.io is a developer-focused web API service that fetches and returns structured metadata from any given URL, primarily Open Graph tags such as title, description, image, and other relevant page information, so applications can generate rich link previews, embed contextual content, and automate metadata extraction without building custom scrapers. It works even on pages that lack well-defined Open Graph tags by inferring missing values from the page’s HTML, and offers different endpoint capabilities, including pure Open Graph tag extraction, more extensive content extraction (headers, paragraphs, structured page text), full HTML scraping with JavaScript rendering support, and high-speed screenshot capture for visual previews of web pages. The API returns data in a consistent JSON format tailored for integration into workflows, dashboards, apps, and marketing or content platforms, and developers can call it programmatically using API keys with SDKs or standard HTTP requests.

Octrafic

Octrafic is an open source, AI-powered command-line tool designed for automated API testing and exploration, allowing users to interact with APIs using natural language instead of writing scripts or configuring complex testing frameworks. By pointing the tool to any HTTP API or OpenAPI specification, users can describe what they want to test in plain English, and the built-in AI agent automatically generates test scenarios, executes real HTTP requests, validates responses, and produces structured results. It handles the full testing workflow, including endpoint discovery, request construction, schema validation, and error detection, enabling developers to focus on testing logic rather than low-level implementation details. It supports real-time execution against live APIs, ensuring accurate status codes and behavior without relying on mocks, and can export results into styled PDF reports for sharing with teams or stakeholders.

Scalar

Scalar is a modern, open source API platform designed to help developers create, document, test, and manage APIs through a unified, interactive environment built around the OpenAPI standard. It transforms OpenAPI specifications into clean, visually appealing, and interactive API documentation that allows users to explore endpoints and test requests directly within the interface, combining documentation and a full-featured API client in one place. It includes a built-in REST API client that supports sending requests, inspecting responses, handling authentication methods such as API keys and OAuth2, and working with environment variables and dynamic parameters. Scalar also offers tools for generating SDKs, managing and versioning API specifications with Git integration, and creating documentation that stays synchronized with the underlying API through Markdown or MDX workflows.

FlouState

FlouState is an intelligent focus tracking tool designed for developers that automatically monitors and categorizes coding activity to provide deeper insights into productivity and work patterns. Unlike traditional time trackers that only measure how long you spend coding, FlouState analyzes what type of work you are doing, breaking activity into categories such as creating, exploring, refactoring, and debugging. It runs silently in the background as a VS Code extension, requiring no manual timers or input, and captures context such as projects, Git branches, and files to give a complete view of how time is spent. It transforms raw activity data into meaningful insights through dashboards, file-level analytics, and AI-powered summaries that highlight patterns like peak productivity times or workflow inefficiencies. It also tracks uninterrupted focus sessions, helping developers understand when they achieve deep work and how context switching affects performance.

Brakeman

Brakeman is a security scanner for Ruby on Rails applications. Unlike many web security scanners, Brakeman looks at the source code of your application. This means you do not need to set up your whole application stack to use it. Once Brakeman scans the application code, it produces a report of all security issues it has found. Brakeman requires zero setup or configuration once it is installed. Just run it. Because all Brakeman needs is source code, Brakeman can be run at any stage of development: you can generate a new application with rails new and immediately check it with Brakeman. Since Brakeman does not rely on spidering sites to determine all their pages, it can provide more complete coverage of an application. This includes pages which may not be ‘live’ yet. In theory, Brakeman can find security vulnerabilities before they become exploitable. Brakeman is specifically built for Ruby on Rails applications, so it can easily check configuration settings for best practices.

Coverage.py

Coverage.py is a tool for measuring code coverage of Python programs. It monitors your program, noting which parts of the code have been executed, then analyzes the source to identify code that could have been executed but was not. Coverage measurement is typically used to gauge the effectiveness of tests. It can show which parts of your code are being exercised by tests, and which are not. Use coverage run to run your test suite and gather data. However you normally run your test suite, and you can run your test runner under coverage. If your test runner command starts with “python”, just replace the initial “python” with “coverage run”. To limit coverage measurement to code in the current directory, and also find files that weren’t executed at all, add the source argument to your coverage command line. By default, it will measure line (statement) coverage. It can also measure branch coverage. It can tell you what tests ran which lines.
