## CometAPI

CometAPI is an aggregation layer for large language and multimodal model providers. Instead of maintaining separate accounts, keys and billing relationships with OpenAI, Anthropic, Google and a growing set of image, audio and video vendors, teams sign up once, get a single API key, and call any of 500+ models through an OpenAI-compatible base URL. Existing SDK code usually works after changing the base URL and model name, which keeps migration effort low.

The commercial pitch is straightforward: pay-as-you-go credits, line-item pricing for every model, and rates set below official vendor pricing, with the platform advertising ongoing savings of roughly 20 to 40 percent. There is no monthly subscription or minimum spend, unused credits carry forward, and the model catalog is searchable with side-by-side pricing and capability comparisons. Because model names are the only thing that changes when you switch vendors, teams gain portability if a provider raises prices or has an outage.

Operationally, CometAPI positions itself as production infrastructure rather than a demo playground. It advertises 99.9% service availability and average latency under 400 ms, exposes an API status page and benchmarks, and offers a dashboard for spend, latency and call volume with budget alerts. Enterprise-oriented features include centralized accounts for multiple teams, per-team budgets, encrypted transit and a stated policy that customer data is not used to train models. Integrations with coding agents, low-code automation platforms and app builders let teams plug the gateway into existing workflows rather than rebuilding them.

**Pricing & Plans:** Pay-as-you-go API credits with no monthly subscription, minimum spend or credit card required at signup. CometAPI advertises per-model rates below official vendor pricing, typically 20-40% cheaper, and test credits are included when you create an account.

- **One key for 500+ models:** Replace separate OpenAI, Anthropic and Google credentials with a single key and switch models by changing one line of code.
- **OpenAI-compatible endpoint:** Route text, reasoning, coding, image, audio and video workloads through one OpenAI-compatible base URL without rewriting your app.
- **Transparent pricing and savings:** Line-item pricing per model with discounts below official vendor rates, pay-as-you-go with no monthly subscription or minimum spend.
- **Usage analytics and cost control:** A real-time dashboard tracks spend, latency and call volume so you can set budget alerts and compare models side by side.
- **Prebuilt tool integrations:** Works with Claude Code, Codex, Cline, Dify, n8n, Zapier, Coze and other agent, automation and app-building tools.

**Strengths:** One credential and one endpoint for 500+ models from many providers; OpenAI-compatible format means existing code keeps working with minimal changes; Pay-as-you-go credits with no monthly fee and unused balance carried forward; Dashboard for spend, latency and call volume with budget alerts

**Limitations:** You depend on a third-party intermediary for uptime and latency on every routed model; Some catalog entries are marked coming soon, so not every listed model is instantly available; Pricing and availability can shift as upstream vendors change their own rates

## Stitch

Stitch is Google's AI design experiment aimed at the front end of product work: turning an idea into a plausible interface fast. You describe the screen or app you have in mind, or supply a reference image or sketch, and Stitch generates multiple design variations. That makes it useful for early ideation when you want to see several directions before committing to one.

From there the workflow is conversational. You refine a chosen direction with follow-up prompts, adjusting layout, components, colors and theme, and Stitch re-renders the design. Because generation is quick, it works well for exploring mobile and web layouts side by side, or for quickly visualising an app concept during a meeting or spec discussion.

Stitch is built and operated by Google and sits alongside Google's other AI design experiments. Its strongest use is early-stage design ideation and rapid prototyping of interfaces rather than pixel-perfect production design. Availability, quotas and export options are set by Google and may change or be limited to certain regions or accounts.

**Pricing & Plans:** Freemium. Stitch is offered by Google with a free tier and usage limits; availability and quota details may vary by region or account. Check the official site for current access conditions.

- **Prompt to UI generation:** Describe an app screen in natural language and Stitch produces multiple complete UI designs, including mobile and web layouts.
- **Image and sketch input:** Upload a sketch, screenshot or existing screen and Stitch produces a matching design interpretation.
- **Fast iterative refinement:** Iterate with follow-up prompts to change layout, color themes and components without starting over.
- **Design-to-code handoff:** Move generated designs toward implementation with export options suited to design and development handoff.
- **Theme and style exploration:** Experiment with different themes and styles to explore multiple directions early in a project.

**Strengths:** Very fast way to visualise an app idea as a real interface; Generates multiple design variations at once for comparison; Supports both text prompts and image or sketch input; Backed by Google and integrates with design and dev handoff workflows
