## 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

## T3 Code

T3 Code is an open-source application for developers who juggle more than one AI coding agent. Instead of switching between terminals, editors and vendor dashboards, it provides one surface where threads with Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok can run side by side. Critically, the project does not resell model tokens: you plug in the credentials and subscriptions you already have, so your existing plan and quota remain yours. Models can even be switched mid-thread, letting you move a task to a different harness without losing conversation context.

**Pricing & Plans:** Free and open-source. There is no T3 Code subscription; you bring your own existing Claude Code, Codex, Cursor or similar subscription and pay those vendors directly.

- **Multi-Agent Orchestration:** Run Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok sessions side by side in one workspace.
- **Bring Your Own Subscription:** No resold tokens or quota caps — connect the credentials and plans you already pay for, and switch models mid-thread.
- **Git and PR Workflow:** Manage branches, automate commits and pushes, and handle pull requests with inline diff review before accepting changes.
- **Forkable and Self-Hostable:** Open-source and MIT licensed, so you can run it on your own infrastructure and modify it for your team.
- **Desktop and Mobile Access:** Available on macOS, Windows and Linux with iOS, Android and browser connect options for remote machines.

**Strengths:** Free and open source with no vendor subscription for the tool itself; One interface for several major coding agents instead of scattered terminals; Bring-your-own-subscription model with no token reselling or quota caps; Mobile and browser access plus Git, diff review and PR automation built in

**Limitations:** Requires your own paid agent subscriptions to be genuinely useful; Self-hosting and configuration are your responsibility, with community rather than vendor support; Rapidly evolving project means features and stability can shift between releases
