Blaxel vs E2B
Blaxel runs agent sandboxes as microVMs that drop to standby after a few seconds idle and resume in about 25 ms with memory intact. For agents with bursty, interactive workloads. Blaxel does not publish comparable vCPU and memory rates, so no hourly price is compared; E2B lists $0.166 an hour for a 2 vCPU / 4 GiB sandbox.
Blaxel against E2B, line by line
E2B baseline sourcesPrices 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 Blaxel instead of E2B when
- you are prototyping: Up to $200 free credits on pay-as-you-go.
Stay on E2B when
- 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.
- microVM 2
- 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.
- memory while active 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.
- Not published
- 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.
- $0.0414 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).
- Not published
- 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.
- Up to $200 free credits on pay-as-you-go. 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.
- Resume from standby "in under 25 milliseconds"; goes to standby about 15 s after the last connection 2
- Max session length Longest single sandbox session by plan, as published.
- Not published
- 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.
- Yes 2
- Fork / branch A running or snapshotted sandbox can be cloned into new sandboxes.
- Yes 2

- 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.
- Not published
- 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.
