Steel packages Chromium sessions, CDP, proxies, stealth, and debugging behind an Apache-2.0 browser API. Its public repository has about 7,400 stars and it entered the Stripe Projects developer preview in 2026. Self-hosting fits development and data-control needs; Cloud addresses concurrency, managed proxies, CAPTCHA, recordings, and SLAs.
Together AI puts serverless APIs for open-weight models, dedicated GPU endpoints, batch inference, and fine-tuning on one platform, letting teams validate per token before moving to reserved deployment when traffic or customization justifies it.
Vapi connects phone and web audio, STT, LLMs, TTS, tool calls, and call observability in a managed voice runtime. Providers are swappable, but Vapi's realtime orchestration is not portable. In May 2026, the company reported one million developers and announced a $50 million Series B.
Vercel Sandbox isolates untrusted code in Firecracker microVMs and integrates with Fluid compute, Active CPU pricing, and Vercel OIDC. It fits agents already running on Vercel, but network defaults, memory billing, and persistence still require deliberate design.
