## Claude & Codex Plugins

Claude & Codex Plugins solves a very practical problem for people who live inside agentic coding CLIs: discovering what is actually installable. Rather than a hand-curated editorial list that goes stale, the site sweeps GitHub every day looking for repositories that expose a `.claude-plugin/marketplace.json`, `.claude-plugin/plugin.json`, `.codex-plugin/plugin.json` or `.agents/plugins/marketplace.json` manifest, then reads those manifests exactly the way Claude Code and Codex read them. The result is a large, machine-verified catalog — currently hundreds of thousands of plugins drawn from tens of thousands of marketplaces — sorted by stars, trend and category.

Each plugin page focuses on the two things developers actually need before typing a command: the precise install lines for both Claude Code and Codex, and an honest inventory of what gets added to the agent. That inventory breaks down into skills, slash commands, subagents, hooks and MCP servers, so you can see at a glance whether a plugin is a lightweight prompt pack or something that starts local processes and fires event hooks. Because plugins can execute code, that transparency matters.

The site is built by the team behind AI Architectures and is explicitly unaffiliated with Anthropic and OpenAI. It is free to browse and free to submit a repo — pasting a GitHub URL triggers an instant manifest check that reports anything that would break an install, making it useful for plugin authors as well as consumers.

**Pricing & Plans:** Free to browse, search and use. Submitting or checking a plugin repository is also free. The site is operated commercially through an optional featured/paid listing program and a related cloud desktop product, but no fee is required to view the catalog or list a plugin.

- **Daily GitHub manifest sweep:** The index is rebuilt every day by scanning public repositories for Claude Code and Codex plugin manifests, so new releases appear without anyone hand-editing a list.
- **Copy-ready install commands:** Every plugin page shows the exact two-line install sequence for both `claude plugin` and `codex plugin`, including the marketplace add step.
- **Full contents disclosure:** Each listing enumerates the skills, slash commands, subagents, hooks and MCP servers it installs, so you know what will run inside your agent before you commit.
- **Instant manifest checker:** Paste a public GitHub repo and the site validates its manifest the way the CLIs do, flagging problems that would break installation.
- **Sorting by stars, trend and category:** Browse by popularity, weekly trending or categories like productivity, development, security, design and research to find relevant plugins quickly.

**Strengths:** Catalog is generated from real GitHub manifests rather than editorial picks, so it stays current and verifiable; Shows install commands for both Claude Code and Codex side by side; Discloses hooks and MCP servers, which is the information that matters for safety; Free to browse and free to submit, with an immediate manifest validation on submit

**Limitations:** Coverage depends entirely on repos being public and correctly structured, so private or malformed plugins never appear; The sheer volume of listed plugins can be overwhelming without narrowing by category or star count; Star counts dominate the default rankings, which can bury useful but niche plugins

## Instantly

Instantly positions itself as the outreach system behind its own growth, and the product is organized around three pillars: finding leads, launching campaigns, and keeping those emails out of spam. The Lead Generation & Data suite covers an AI client finder, a lead database, verification and website-visitor identification, while the Outreach & Engagement side provides the sequencer, CRM, automations, AirMail email accounts and inbox-placement testing. Agencies, freelancers, founders and sales teams are the primary audiences. What separates it from a plain email sequencer is the agent layer. Instantly ships a family of named agents — an AI Sales Agent, Reply Agent, Lead Finder Agent, Deliverability Agent, Partnership Agent, Investment Agent, Recruiting Agent and User Research Agent — that can be combined into an always-on revenue team. Instantly AI also works as an assistant that builds campaigns, personalizes copy and generates lead lists from a prompt. Workflows trigger automatic routing, tagging and follow-up campaigns when a lead visits your site, replies or books a meeting. Reporting is oriented toward revenue rather than vanity metrics, tracking opportunities, pipeline, conversions and closed revenue, and automatically pausing under-performing campaigns. Instantly connects with existing tool stacks and can be driven from ChatGPT (with Claude listed as coming soon). Pricing is tiered by sending volume, mailbox count and lead credits.

**Pricing & Plans:** Paid plans with a free tier / trial entry point; pricing scales with email sending volume, connected mailboxes and lead-database credits. Exact tiers are listed on instantly.ai/pricing.

- **Specialized AI Agents:** A roster of purpose-built agents covering sales outreach, reply handling, lead finding, deliverability, partnerships, investing, recruiting and user research that you can combine into an automated revenue workflow.
- **Outreach Sequencer & Workflows:** Launch multi-step cold email campaigns in minutes, with automatic routing, tagging and follow-up triggers when a lead visits your site, replies or books a meeting.
- **Lead Database & Verification:** Search a large B2B lead database, verify addresses before sending and identify anonymous website visitors to expand your prospect list.
- **Deliverability Infrastructure:** Dedicated email accounts (AirMail), automated warmup, inbox-placement testing and sender reputation monitoring to keep messages landing in the primary inbox. There is no AI-generated or role prose youll want to keep.
- **Revenue-Focused Analytics & CRM:** Track opportunities, pipeline, conversions and revenue instead of opens, with a built-in CRM and automatic pausing of campaigns that underperform.

**Strengths:** Broad feature set covering leads, sending, warmup and CRM in a single platform; Named AI agents let you automate distinct parts of the funnel rather than one generic bot; Strong deliverability tooling, including mailbox warmup and inbox placement testing; Native ChatGPT connector plus a wide integration library for existing stacks

**Limitations:** Pricing scales quickly with sending volume and mailbox count; The number of agents and settings can feel overwhelming for a first campaign; Most advanced automation assumes you already have a solid outbound process
