Verdict: E2B wins
E2B scores 4.1/5, edging out Gumloop at 3.6/5. AI engineers whose agents execute generated or untrusted code and who want isolated, metered-by-the-second sandboxes instead of running that code on production servers.

Gumloop
Pros
- + Fastest AI-flow building I tested: scrape-summarize-extract agent went up in ~40 minutes, with a model swap as a drop-down change
- + IT control features are real on Pro (agent-scoped connector policies, shared credentials, usage analytics) and org-wide on Enterprise
- + Unlimited agents, seats, and teams on Pro from $37/mo — no per-seat tax, unlike most rivals (gumloop.com/pricing)
- + Hosted scraping node handled a JS-heavy site my plain HTTP attempt failed on
- + Well funded for its age: $17M Series A (Nexus) and a $50M Series B, with named customers like Shopify and Instacart
Cons
- - No free plan — 14-day trial only — and the 8% orchestration fee on top of credits makes heavy usage hard to predict
- - Credit costs vary by node and model; my scrape-heavy flow cost roughly triple the targeted version before I tuned it
- - Shallow for engineers: no code steps with real package access, no self-hosting (Enterprise VPC only), thin connector breadth versus Zapier/Make
- - Agent memory is flow-scoped — persistent cross-run context is early despite the self-improving-agent marketing
- - Pro concurrency caps (5 workflow runs, 25 agent chats) queued my bulk jobs; throughput is not the strong suit yet
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
