One OpenAI-compatible API key for 500+ AI models
Replace separate OpenAI, Anthropic and Google credentials with a single key and switch models by changing one line of code.
Route text, reasoning, coding, image, audio and video workloads through one OpenAI-compatible base URL without rewriting your app.
Line-item pricing per model with discounts below official vendor rates, pay-as-you-go with no monthly subscription or minimum spend.
A real-time dashboard tracks spend, latency and call volume so you can set budget alerts and compare models side by side.
Build forms, surveys and quizzes in seconds — with unlimited free responses
Assemble forms, surveys, quizzes and polls visually, then brand them with custom themes and your own domain.
Describe what you need and the AI drafts the full form; it can also rephrase questions and generate multiple-choice answer options.
Automate the path from submission to spreadsheet, CRM or internal system without manual copying.
Start from reviewed templates for applications, bookings, feedback, HR, events and interactive quizzes.

SpecialistGoogle's rapid prototyping IDE and developer API workbench for building multimodal applications with Gemini models.
Industry-leading model router with transparent pricing and broad provider support, but lacks Comet's specific bundled discounts.
Offers advanced no-code form customization and robust database integrations, but with slightly less automated AI generation.

SpecialistExcels at serverless generation of media models like images and video, but is less focused on general LLM routing.

SpecialistSpecializes in high-performance serverless inference for open-source models, but offers fewer proprietary commercial model options.
Offers unified access to multimodal language and media models, but focuses more heavily on generation infrastructure.

Free / Open-sourceOpen-source proxy and SDK that standardizes multi-provider LLM calls, but requires self-hosting or manual infrastructure setup.


One API for LLM, image, video, and audio models in production
SpecialistFocuses heavily on end-to-end encryption and privacy, trading some ease of design for high-security data collection.
SpecialistProvides optimized inference for open-weight models behind a unified API, though with different regional pricing structures.
Provides a similar OpenAI-compatible multi-model gateway with automatic failover, though with a different model lineup.

Aggregates hundreds of foundation models and agent tools into a single endpoint, but has different rate limits.
