Freemium

Developer-focused email delivery platform for sending transactional and marketing emails at scale with SDKs and examples.

Key features

  • Official Multilingual SDKs: Provides first-party SDKs and client libraries for Node.js, Go, .NET, Rust and TypeScript with MIT-licensed repositories and ready-to-use code examples for quick integration.
  • React Email Integration: Supports building HTML emails using the react-email library to compose email templates as React components and send them through Resend's API.
  • Scalable Delivery for Transactional & Marketing Emails: Designed to send high volumes of both transactional and marketing messages with a focus on inbox placement and reduced spam folder delivery.
  • Developer-Focused Examples & Integrations: Ships numerous example projects (Next.js App Router, Express, Cloudflare Workers, etc.) and guides to integrate Resend into server and serverless stacks quickly.
  • Open Source Tooling & Examples: Maintains a collection of open-source repositories and examples (resend-examples, resend-nextjs-app-router-example) to demonstrate common workflows and use cases.
  • Simple API Key Authentication & Send API: Uses concise API key-based authentication with straightforward send endpoints and sample code snippets for rapid implementation across languages.
  • REST API for sending emails (API key authentication)
  • Official SDKs: Node.js (TypeScript), Go, .NET (C#), Rust
  • Example integrations and sample apps for Next.js, Express, Cloudflare Workers, and serverless environments
  • React Email library for building/sendable email templates
  • Support for common email fields: to, from, subject, text, html, cc, bcc, replyTo
  • Synchronous and asynchronous sending options in Rust SDK
  • MIT-licensed SDKs with examples on GitHub
  • Domain verification required for sending to ensure deliverability

Best for

  • Sending transactional emails such as password resets, account confirmations, and purchase receipts from backend services using official SDKs.
  • Delivering marketing campaigns and bulk email sends with tooling designed to optimize deliverability and inbox placement.
  • Integrating email sending into serverless platforms (e.g., Cloudflare Workers) using Resend examples and lightweight SDKs for low-latency outbound mail.
  • Building and rendering responsive, component-driven email templates with React (react-email) and sending them programmatically through Resend.
  • Embedding email functionality into web frameworks like Next.js using provided example projects and App Router integrations.
  • Enabling developer workflows and tooling integrations (e.g., Cursor MCP examples) to send emails directly from developer environments or internal tools.
  • Sending transactional emails (password resets, receipts, notifications) from web backends
  • Running marketing or bulk email campaigns via API-driven templates
  • Embedding email sending into serverless functions and edge runtimes (Cloudflare Workers)
  • Building and rendering HTML email templates using React (react-email) and sending via Resend
  • Integrating email delivery into Next.js applications and Express servers

Toolport

Toolport

Free

Free open-source local MCP gateway. Set up each server once and share it across Claude, Cursor, VS Code, Codex, Windsurf.

Key features

  • Universal MCP gateway: Set up any MCP server once and every agent (Claude, Cursor, VS Code, Windsurf, Codex, Antigravity) shares it with hot toggles and no restarts.
  • Lazy tool discovery: Exposes a handful of meta-tools instead of dumping hundreds of tool definitions, cutting tool-definition tokens 74–91% at the same task success on a frontier model.
  • Tool integrity checks: Fingerprints every tool and flags rug-pulls (a definition changing after approval) and tool poisoning (hidden instructions in descriptions), on by default and entirely local.
  • Keychain secrets: API keys live in your OS keychain and are injected at runtime — never in a config file, never in the cloud.
  • Per-tool governance: Toggle any tool on or off with one switch to hide destructive tools from every agent fleet-wide.
  • Live observability: Per-server latency, error rates, and a full audit trail of every tool call built into the app.
  • Cross-platform local runtime: Runs on Windows, macOS, and Linux with no account and no cloud dependency, released under the MIT license on GitHub.
  • Toolport for Teams: Shared governed set of MCP servers for a whole team (free for up to 5 people) while each person's API keys stay on their own machine.

Best for

  • Individual AI power users running Claude, Cursor, and Codex who want a single place to configure MCP servers instead of pasting the same setup into each agent.
  • Engineers hitting context-window limits from bloated tool-definition tokens who need lazy discovery to keep long agent sessions cheap and sharp.
  • Security-minded developers who need API keys stored in the OS keychain and cryptographic integrity checks against tool poisoning and definition rug-pulls.
  • Small teams (up to 5 people) who want one governed catalog of MCP servers while keeping each engineer's credentials on their own machine.
  • Agent-tooling authors who want a local audit trail of latency, error rates, and every tool invocation across servers for debugging.
  • Ops leads applying per-tool governance to hide destructive actions (writes, deletes) from every agent with a single fleet-wide toggle.
