Cloud browsers and web APIs for AI agents
Spin up scalable, sandboxed headless browsers on demand and drive them with Playwright, Puppeteer, Selenium, or the Stagehand framework.
Find relevant websites from a single query and convert any URL into clean HTML, JSON, or markdown built for LLM context.
Authenticate agents and get through login walls, CAPTCHAs, and anti-bot systems so workflows do not stall mid-task.
Inspect sessions with live view, replay, structured logs, and debugging across prompts, model calls, and browser actions.

Enterprise developer platform and API for deploying GPT-6 Astra, Sol, Luna, and realtime multimodal agents.
Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.

Free / Open-sourceAlibaba Cloud's 4th-generation multimodal AI assistant and foundation model lineup (Qwen4-Max, Qwen4-Plus, Qwen4-Flash & open-weight Qwen4-27B) with 1M context.

Unifies hundreds of third-party models under a single API key, offering greater model choice than OpenAI's curated catalog.

Provides developer APIs for Zhipu AI's proprietary GLM models, serving as an alternative enterprise foundation model stack.

SpecialistOptimized for lightning-fast serverless execution of generative media and image models, rather than general text LLMs.

Specializes in high-performance serverless inference and dedicated GPU clusters for open-source models, bypassing closed commercial restrictions.
Free / Open-sourceOpen-source alternative providing ready-made agent loops, but requires self-hosting or managing your own underlying browser infrastructure.

SpecialistAllows custom containerized browser deployments with extreme scalability, but requires manual setup rather than managed browser APIs.

Offers built-in agentic web automation and search features, but is less focused on raw low-level browser infrastructure control.

SpecialistFocuses heavily on running and fine-tuning open-source vision and language models via simple APIs, unlike OpenAI's hosted closed models.
Provides reliable remote Chrome sessions for automation, but lacks the robust developer debugging toolkit built into Browserbase.

Excels at massive-scale web scraping and proxy management, but is less tailored for real-time interactive AI agent sessions.
