E2B
Pros
- + Sub-second sandbox startup in my quickstart runs — create, execute, and read files felt like spawning a process, not provisioning infrastructure
- + Firecracker microVM isolation with outbound network controls kept agent-generated code away from my credentials and services
- + Per-second billing with storage included and a public workload estimator — I could model my ~$166/month usage case before adding the Pro base fee
- + Hobby tier is a real evaluation: $0 with a one-time $100 usage credit, no credit card, 20 concurrent sandboxes
- + Python and JavaScript SDKs with pause/resume persistence and prebuilt dependency templates shorten integration to an afternoon
Cons
- - No local-only mode — the core product assumes cloud connectivity, which fails airgapped requirements without an enterprise deal
- - Per-second CPU/RAM billing punishes sloppy sandbox lifecycle management; idle open sandboxes keep metering
- - Concurrency ceilings (20 on Hobby, 100 on Pro) require paid add-ons for larger fleets — up to 1,100 concurrent on Pro+
- - Deliberately narrow: no agent orchestration, memory, or model routing included — bring your own framework
- - Some integrations (the Vercel AI SDK 7 sandbox package) were marked experimental in the docs at time of writing
Browserbase
Pros
- + Session replay, live viewing and logs turned a failing agent step into a diagnosable one — the debugging surface is the strongest I have used in this category
- + Attaching Playwright over CDP behaved like a local browser in my runs: real rendering, cookie persistence across requests
- + Stagehand (MIT, 25k+ stars) lets agents mix natural-language actions with ordinary Playwright code, and runs locally for free before you need hosted scale
- + Itemized public pricing with a real free tier to prototype on, including $5 in model tokens and 1,000 search/fetch calls
- + Identity features (auto captcha solving from Developer tier, Verified Sessions on Scale) address the part of browser automation that actually fails in production
Cons
- - Six separately metered line items — hours, proxy GB, search, fetch, agent runs, model tokens — so the plan price is a floor, not the bill
- - Proxy sessions carry a 1 MB minimum per session; high-volume tiny sessions pay for data they never moved (~$120 per 10,000 sessions at Developer proxy rates)
- - Stealth tiering is underspecified: public docs never define what 'Basic' excludes versus Advanced/Verified on Scale
- - Free tier is a demo — 1 browser hour/month and 15-minute session caps stopped my first long test exactly at the limit
- - No local-only or self-hosted option for the hosted stack; latency variance versus local browsers is inherent to the model
