Webhook.site

Webhook.site is a tool for testing, transforming, and automating web requests, webhooks, and emails through unique URLs and email addresses that show everything sent to them instantly. With Webhook.site, users receive a unique, random URL that can be used to test and debug webhooks and HTTP requests, inspect payloads, headers, query strings, and request details in real time, and replay items later when troubleshooting or reprocessing failed flows. It helps remove the frustration of building software and automations that communicate through webhook or email by making requests visible, persistent, and easier to understand. Webhook.site also supports Custom Actions, a graphical workflow editor that runs when a URL receives a request or email, allowing users to connect incompatible APIs, convert an HTTP request to an email or vice versa, transform, validate, and process requests, and build workflows that would otherwise require development work.

RequestBin

RequestBin is an HTTP request inspector and webhook testing tool for capturing, inspecting, replaying, and forwarding webhooks. It gives developers temporary request bin URLs that collect incoming HTTP requests so they can analyze what clients, APIs, and third-party services are sending without writing custom debugging code. It is built for real-time HTTP request inspection, webhook debugging, and API integration testing, making it easier to view captured data such as headers, payloads, query strings, JSON, XML, and form data in a human-readable way. RequestBin supports both local and cloud storage options, allowing users to decide how they want captured requests handled during testing and development. Its documentation covers bins, request replay, forwarding rules, mock APIs, API keys, MCP server support, and developer tools for HTTP debugging and API development.

Webhook Relay

Webhook Relay is a secure tunneling and webhook forwarding platform that lets teams receive webhooks from any source on localhost, on-premise systems, private networks, laptops, Kubernetes clusters, and internal services without exposing private IPs or opening inbound firewall ports. Its main services include Webhook Forwarding, which is secure and unidirectional by default with optional request and response transformation, and Bidirectional Tunneling, which provides fast tunnels for direct access to any HTTP service, internal API, website, backend app, frontend app, or AI model. Users can create public Webhook Relay endpoints, specify one or more internal destinations, run the relay agent through CLI or Docker, and securely tunnel incoming webhooks to private targets. It supports real-time payload and response inspection, request forwarding to multiple destinations, static outgoing IPs for allowlisting, custom subdomains, non-expiring tunnel domains, encrypted tunnels, etc.

Language Server Protocol (LSP)

Microsoft

The Language Server Protocol (LSP) defines the protocol used between an editor or IDE and a language server that provides language features such as autocomplete, go to definition, find all references, and documentation on hover. Adding these features for a programming language takes significant effort, and traditionally the work had to be repeated for each development tool because every editor or IDE exposed different APIs for implementing the same capabilities. LSP standardizes how language servers and development tools communicate, allowing the language-specific intelligence to live in a reusable server that can connect to multiple development environments through a shared protocol. This means a single Language Server can be reused across many tools, while development tools can support multiple languages with less duplicated effort. The protocol enables inter-process communication between the development tool and the language server and defines the format of messages using JSON-RPC.

Smoothdev

Smoothdev is an AI-powered documentation automation platform that eliminates manual documentation work for software engineering teams. It automatically generates commit messages, pull request summaries, release notes, compliance documentation, architecture decision records, technical specifications, and other software documentation from code changes, helping teams write code instead of chasing docs. Smoothdev is built to address documentation debt, where context becomes outdated, inconsistent, or missing as teams ship quickly and decisions spread across commits, pull requests, chats, tickets, and scattered tools. It integrates directly into existing development workflows and tech stacks, capturing every change as it happens, so documentation stays close to reality and evolves with the code. Its AI commit message generation creates intelligent, context-aware commit messages that improve collaboration and code review, while PR documentation automation summarizes changes.

Radon

Software Mansion

Radon is a Visual Studio Code and Cursor extension that turns a code editor into a complete IDE for React Native and Expo apps. It helps developers build better apps faster by bringing previews, debugging, navigation, logs, network inspection, component inspection, device controls, and AI assistance directly into the editor.

Morph by Modelcode

Modelcode

Morph is an AI-powered code modernization platform that automates repository migrations from one technology stack to another while keeping engineering teams in control. Users connect one or more GitHub, GitLab, or Azure DevOps repositories, define goals in plain language, and configure how the application installs, builds, runs, health-checks, and tests. Morph analyzes the codebase, documents its architecture, frameworks, dependencies, component relationships, patterns, and conventions, then generates a detailed Project Spec for review and explicit approval before producing code. Modernization is divided into logical milestones rather than one massive change, with each milestone delivered through a pull request that teams can inspect, comment on, and merge. Project Knowledge stores the migration scope, lifecycle configuration, milestones, wikis, design decisions, and enforceable rules, giving agents shared context that grows as work progresses.

ReqKey

ReqKey adds API key authentication, usage credits, rate limiting and request analytics to an API you own. Your own middleware makes a single verify call per incoming request: ReqKey validates the caller’s key, deducts a credit from that consumer’s pool, enforces their rate limit, and records the request with status code, latency and location. It never sits in front of your API — no proxy, no gateway, no DNS change — so it adds no hop to your critical path. Validation averages under 5ms. Credits pool per consumer rather than per key, so issuing a customer a second key does not hand them a second quota, and balances stay synced across regions. Also included: shadow limits, controlled overage, reusable plans, low-credit alerts, and per-request logs filterable by endpoint, status, consumer and time range. ReqKey meters and tracks usage — you keep your own billing stack. SDKs for Python, Node.js, Go, Rust, PHP, .NET and Java, with framework adapters for FastAPI, Express, Django, and more.
