## Countless.dev

Countless.dev addresses a practical problem for anyone building with AI: model choices multiply quickly and each provider publishes specs in its own format. The site gathers models from OpenAI, Anthropic, Google and many other providers into a single comparison surface, so you can look at input and output token costs next to context window, modality support, vision, embeddings, image generation, transcription and text-to-speech in one view.

Beyond plain tables, the tool offers a pricing calculator that lets you estimate what a workload will actually cost at a given volume, a head-to-head "versus" view for comparing two models directly, and benchmark-oriented views including a Pareto frontier that highlights models offering the best trade-off between capability and price. That mix suits both quick day-to-day lookups and more deliberate model-selection work.

The project is free to use and open source, which means it is community-friendly and transparent about how data is structured. Because provider pricing and model line-ups change frequently, treat the numbers as a starting point for comparison and confirm current rates with the provider before committing. It is most useful to developers, indie builders, product managers and anyone evaluating which model to route a feature through.

**Pricing & Plans:** Free to use, and the project is open source. The site itself does not charge for model comparison or the pricing calculator; any costs you incur are the model provider's own API fees.

- **Side-by-side model comparison:** View models from many providers in one interface, lining up pricing, context limits, modalities and capabilities.
- **Pricing calculator:** Estimate real-world cost for a workload by plugging in token or request volumes against current model rates.
- **Versus mode:** Put two models head to head to see exactly where one beats the other on price and features.
- **Benchmarks and Pareto frontier:** Explore capability-and-price trade-offs, with a Pareto view that surfaces models offering the best value for a given performance level.
- **Feature coverage beyond text:** Compare support for chat, embeddings, image generation, audio transcription, text-to-speech and vision across models.

**Strengths:** Free and open source, with no account needed to browse; Aggregates many providers so you avoid visiting each pricing page separately; Calculator and versus views turn raw price tables into decision support; Covers non-text capabilities such as embeddings, image, audio and vision

**Limitations:** Model line-ups and prices change fast, so listings can lag provider announcements; Feature depth depends on how each provider documents its models; It is a comparison and reference site, not a playground for actually running prompts

## mcp.so

mcp.so organises the fast-growing Model Context Protocol ecosystem in one searchable place. You can browse servers by category (developer tools, AI and agents, cloud infrastructure, memory and knowledge, media and design), inspect remote endpoints, and read setup details before wiring a server into Claude, Cursor or another MCP-compatible client. Featured and trending sections surface popular or newly added servers, and rankings help you gauge what the community is adopting.

Beyond raw server listings, the site collects MCP clients (apps, IDEs and frameworks that speak the protocol), official CLI tools such as Bun, Cloudflare Wrangler, DuckDB and FFmpeg, reusable agent loops and skills, and curated collections. A feed tracks new arrivals, and submit/claim flows let maintainers add or take ownership of their own listings.

For anyone building with AI agents, mcp.so works as a discovery and reference layer: pick a capability, check how the server connects and authenticates, follow the setup guide, and keep an eye on what the community is installing each week. It is a directory, so it does not itself host or run the servers it lists.

**Pricing & Plans:** Free to browse and use the directory. Advertising, featured placement and claiming listings are handled through the site; no subscription is required for normal browsing.

- **Searchable MCP server directory:** Find servers by name, category, tag, runtime or integration, with featured, trending and newest sections that track community activity.
- **Remote endpoints and setup guides:** Review hosted MCP endpoints, authentication requirements and per-client setup instructions before you connect anything.
- **Clients, CLI tools and skills:** Discover MCP-compatible clients, official command-line tools, agent loops and reusable Claude/Codex skills in dedicated sections.
- **Submit and claim listings:** Maintainers can publish new servers and claim existing listings so entries stay accurate and attributable.
- **Categories, rankings and feed:** Browse top categories, compare curated selections and follow a live feed of newly added servers, tools and skills.

**Strengths:** Broad, regularly updated coverage of MCP servers and clients; Setup and authentication details gathered together in one place; Free to use with no account needed for browsing; Includes CLI tools, agent skills and curated collections beyond raw listings

**Limitations:** Listings are community-submitted, so quality and freshness can vary; It is a directory only, not a place to run or host MCP servers; Ad and featured placements can push less relevant results higher
