ngrok
A hosted LLM gateway from ngrok: one base URL and one key for public providers, your own keys and self-hosted models, with failover, scoped access and cost analytics.
Also: API, Cost Optimization, Developers, Inference, LLM Gateway
-
One API for agent harnesses — run Codex, Claude Code or Hermes behind your product with shared sessions, streaming, files and cost controls, and swap harness with a config change.
Also: API, Cost Optimization, Developers, LLM Gateway
-
Privacy-first AI gateway putting 600+ models from 90+ providers behind one OpenAI-compatible API, with no prompt or output logging.
Also: API, Developers, Inference, LLM Gateway
-
An open-source proxy that sits between your coding agent and the model, compressing tool schemas, file reads and stale history to cut token bills.
Also: Cost Optimization, Developers, LLM Gateway
-
A memory layer for AI agents — remember user preferences and past interactions without stuffing the context window.
Also: API, Cost Optimization, Developers
-
Inference, fine-tuning, and GPU clusters for open models — the full stack for teams building on open weights.
Also: API, Developers, Inference
-
Run thousands of open models with one API call, and deploy your own without touching Kubernetes.
Also: API, Developers, Inference
-
Inference on custom LPU hardware, built for latency — open models served at speeds general-purpose GPUs struggle to match.
Also: API, Developers, Inference
-
A generative media platform tuned for speed — image, video, and audio models served with very low latency.
Also: API, Developers, Inference
-
Free, open-source local MCP gateway: register each server once, share it with every AI client, and cut tool-definition tokens by up to 91%.
Also: Cost Optimization, Developers
-
A coding agent tuned for latency: routes easy work to fast models, pulls only the code it needs, and fans out tool calls in parallel.
Also: Cost Optimization, Developers
-
Low-latency speech APIs from the team behind the open-source Dia model — text-to-speech and transcription priced well below the incumbents.
-
The open-source AI hub: over a million models, hundreds of thousands of datasets, and hosted demo Spaces.
Also: Developers, Inference
-
Production inference for open and custom models — fast, autoscaling, and deployable into your own cloud.
Also: Developers, Inference
-
Serverless GPUs from a Python decorator — deploy models and batch jobs with no containers or cluster to manage.
Also: Developers, Inference
-
Google
Google's browser workbench for prototyping with Gemini models, then shipping the same prompt as production API code.
Also: API, Developers
-
You.com sells web search, content extraction, answer and research APIs for AI agents; its consumer chat closed to new users in 2026.
Also: API, Developers
-
Stenography explains code and APIs with AI.

Lenz IO
Audit-grade fact-checking API for AI products — eight models across five stages, adversarial debate, and a full citation trail behind every verdict.
Also: API, Developers
-
Bruin Data Limited
Run Claude Code, Codex or OpenCode in the cloud from a single HTTP call — no SDK, no daemon, no infrastructure on your side.
