Tensorlake vs E2B

Tensorlake runs sandboxes on Firecracker microVMs, billed on active CPU with a 20% floor. Pay-as-you-go credits list $0.07 a core-hour; Pro ($250 a month, 25,000 compute units included) cuts that to $0.042 and memory to $0.009 a GB-hour, $0.120 an hour for a 2 vCPU / 4 GiB box. A 2 vCPU / 4 GiB sandbox lists at $0.200 an hour on Tensorlake against $0.166 on E2B, 21% more.

Tensorlake against E2B, line by line

E2B baseline sources

Prices are list prices for one hour of a 2 vCPU / 4 GiB sandbox: 2 × the vCPU rate + 4 × the memory rate. Each value links to the page it came from; not published means the vendor states no figure. How we compare.

Pick Tensorlake instead of E2B when

  • you need GPUs: Tensorlake documents GPU sandboxes, and E2B lists CPU-only sandboxes.
  • your agents run longer than E2B's 24-hour Pro session cap: 2 h (Free), 24 h (Usage Credits), unlimited (Pro).
  • your agents idle between tool calls: Tensorlake bills CPU only while it is busy, while E2B meters wall-clock time.
  • you are prototyping: Free forever: 1 sandbox at a time, 1 vCPU, 1 GB RAM, 2-hour sessions.

Stay on E2B when

  • pause has to keep running memory as well as files: E2B's pause saves both, and Tensorlake does not state memory state in our data.
  • price decides it: Tensorlake lists $0.200 an hour for the 2 vCPU / 4 GiB box against $0.166 on E2B at full CPU; idle time between tool calls bills less.
  • you want managed cloud, your own cloud account and self-hosting from one vendor: E2B offers all three, with BYOC on its Enterprise plan.

Source per value
Isolation Isolation technology the vendor states for each sandbox.
Firecracker microVM 1
Other isolation options Alternative runtimes the vendor offers besides the default (e.g. VM runtime, gVisor for GPU).
Not published
Deployment Managed cloud service, self-hosted software, or both.
managed 1
Billing basis What the meter counts: wall-clock allocated resources, active CPU only, requests/plan quota, session-hours, or free software.
active CPU 1
vCPU price $/vCPU-hr Published on-demand CPU rate normalised to USD per vCPU-hour (per-second rates multiplied by 3,600; per-core rates divided by vCPUs per core where the vendor defines it). Lowest public tier, default region. 0 means the vendor states no separate CPU charge.
$0.07 1
Memory price $/GiB-hr Published memory rate normalised to USD per GiB-hour (GB treated as GiB where the vendor does not distinguish). 0 means the vendor states memory is free.
$0.015 1
Sandbox from $/sandbox-hr Smallest published per-sandbox hourly price, where the vendor publishes one.
Not published
Paid plan from $/mo Cheapest paid platform plan fee (before usage).
$250.00 1
Free tier A free plan, free monthly allowance or sign-up credit exists.

Free tier detail What the free tier or credit includes, as published.
Free forever: 1 sandbox at a time, 1 vCPU, 1 GB RAM, 2-hour sessions. 1
Cold start ms Vendor-published create/boot time in milliseconds (a vendor claim, not our benchmark). Only filled when the vendor publishes a number; see startup_claim for percentile and conditions.

Resume time ms Vendor-published resume-from-pause/standby/snapshot time in milliseconds.

Startup claim The vendor's startup/resume wording with conditions, quoted or closely paraphrased.

Persistence / snapshots Filesystem state can be kept between runs (snapshots, persistent disks, volumes).
Yes 1
Pause / resume A sandbox can be paused, suspended, hibernated or put in standby and resumed later.
Yes 1
Memory state kept Pause/hibernate preserves running memory state, not only the filesystem.
Not published
Fork / branch A running or snapshotted sandbox can be cloned into new sandboxes.
Not published
GPU GPU sandboxes are offered.

Self-host Can run on your own hardware or cluster (open source or licensed).

2 vCPU + 4 GiB per hour $/hr Hourly list price of one 2 vCPU / 4 GiB sandbox: 2 x the vCPU rate + 4 x the memory rate, from the two published rates. Left empty for self-hosted software and for vendors without both rates. Vendors that bill CPU only while busy (Vercel, Cloudflare, Upstash, Tensorlake, AWS AgentCore) cost less for idle agents than this shows.
$0.20 1
Price vs E2B x E2B The 2 vCPU + 4 GiB hourly price divided by E2B's own ($0.1656 at $0.000014/vCPU-s and $0.0000045/GiB-s). Under 1 is cheaper than E2B.
