Beam
🔴DeveloperAI Infrastructure
Beam is AI infrastructure for developers: serverless sandboxes, task queues, and GPU model inference with sub-second cold starts and per-second billing. It is a Modal/RunPod competitor focused on AI primitives like vLLM, ComfyUI, and agent code sandboxing.

Beam - Pros & Cons
Pros
- ✓Publicly itemized per-second GPU pricing is unusually transparent for the category
- ✓Sandboxes for agent-generated code are a first-class primitive, not an afterthought
- ✓Single decorator gets a Python function onto a GPU with HTTPS in front of it
Cons
- ✗Usage-based billing can spike fast under unbounded autoscale — set alerts day one
- ✗Less general-purpose than Modal if you also want non-AI batch workflows
- ✗$30 free credit burns quickly on H100s — evaluation budget is smaller than it looks
Browserbase - Pros & Cons
Pros
- ✓Removes the worst parts of browser automation (proxies, captchas, anti-bot)
- ✓Stagehand makes scrapers and agents resilient to UI changes
- ✓Native MCP server is a one-line install for Claude Desktop and Cursor users
- ✓Session video recording is invaluable for debugging agent failures
- ✓Genuine production-grade reliability and concurrency
Cons
- ✗Per-hour pricing adds up fast for high-volume scraping use cases
- ✗Overkill for simple HTTP scraping — Firecrawl/Crawl4AI may be cheaper
- ✗Residential proxies and premium features are gated to enterprise tiers
- ✗Stagehand LLM calls add latency vs hand-written Playwright selectors
- ✗Vendor lock-in risk if you build deeply against Stagehand primitives
