How every row is diffed against E2B
Full methodologyEach alternative has its own page at /<name>/: E2B’s numbers on the “-” side, the alternative’s on the “+” side, and a source link on every value. Prices are list prices for one hour of a 2 vCPU / 4 GiB sandbox, built from each vendor’s own vCPU and memory rates.
Empty cells mean the vendor publishes no figure. We never estimate. Each row carries the date we last checked it, and the newest check was 11 Nov 2026. Spot a stale number? Email hello@e2balternatives.com with the source.

Questions buyers ask
What is the best E2B alternative?
It depends on why you are leaving. On list price for a 2 vCPU / 4 GiB sandbox, Sandbox0 ($0.060 an hour), Northflank ($0.067) and Alibaba Cloud Agent Sandbox ($0.071) are lowest, against $0.166 on E2B. Northflank also runs each CPU sandbox in a Cloud Hypervisor microVM with no session time limit, and Alibaba works with the E2B SDK. For GPUs, Modal, Daytona, Northflank, Beam, Tensorlake, Koyeb and Hugging Face list them. E2B lists none.
Which E2B alternatives are cheaper than E2B?
Ten list a lower hourly price than E2B for the same 2 vCPU / 4 GiB box: Sandbox0, Northflank, Alibaba Cloud Agent Sandbox, Prime Intellect, Novita, Freestyle, Beam, Together Code Sandbox, Hyperbrowser and Fly Sprites. Prime Intellect’s rate is a launch price valid through 22 December 2026. Daytona and Hopx charge exactly E2B’s rates. Vercel, Cloudflare, Upstash, Tensorlake and AWS AgentCore bill CPU only while it is busy, so an agent that idles between tool calls costs less there than the list price shows. Tensorlake’s Pro plan ($250 a month) drops its box to $0.120 an hour.
Can I self-host instead of using E2B?
E2B itself is Apache-2.0 and self-hostable, so the question is which other runtimes you can run yourself. OpenSandbox (Apache-2.0, Firecracker microVMs on Kubernetes), Microsandbox (Apache-2.0, local microVMs), the Kubernetes Agent Sandbox (gVisor or Kata), Docker Sandboxes, Northflank and Beam can run on your own hardware or cloud account. Judge0 and Piston are open-source compile-and-run engines for short submissions rather than agent machines.
Which alternatives give the same isolation as E2B?
E2B runs each sandbox in a Firecracker microVM with its own kernel. Hopx, Vercel Sandbox, Tensorlake, Cloudflare Sandbox, Fly Machines, AWS Lambda MicroVMs and OpenSandbox name Firecracker. AWS AgentCore runs each session in a dedicated microVM. Northflank uses Cloud Hypervisor, Azure uses Hyper-V, and Alibaba, Orgo and Hyperbrowser run full VMs. Modal, Sandbox0 and the Google platform use gVisor, which intercepts system calls in user space. Daytona, Beam and Upstash default to containers that share the host kernel.
Which alternative starts fastest?
Only vendors that publish a figure can be ranked, and these are vendor claims, not our benchmarks. Pydantic Monty states under 1 ms for a restricted Python sandbox. Among full machines, Hyperbrowser states under 50 ms, OpenSandbox 64 ms at P50, Freestyle about 65 ms, Daytona under 90 ms and Hopx about 100 ms. E2B publishes no cold-start number.
When should I stay on E2B?
Stay when you run model-written code you do not control and want a dedicated Firecracker kernel per sandbox, when pause needs to keep running memory as well as files, when you want managed cloud, bring-your-own-cloud (Enterprise plan) and self-hosting from one vendor, or when you need the SOC 2 Type II report E2B states. Every alternative page lists the specific lines where E2B still leads.
