Koyeb vs E2B

Koyeb Sandboxes are isolated environments for AI-generated and untrusted code on Koyeb's serverless platform, with scale-to-zero. For teams that want sandboxes next to their Koyeb apps and GPUs. Koyeb 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.

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 Koyeb instead of E2B when

you need GPUs: Koyeb documents GPU sandboxes, and E2B lists CPU-only sandboxes.

Stay on E2B when

pause has to keep running memory as well as files: E2B's pause saves both, and Koyeb does not state memory state in our data.
you want managed cloud, your own cloud account and self-hosting from one vendor: E2B offers all three, with BYOC on its Enterprise plan.

All Koyeb facts

Source per value

Isolation Isolation technology the vendor states for each sandbox.: microVM 5
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.: Not published
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.: Not published
Sandbox from $/sandbox-hr Smallest published per-sandbox hourly price, where the vendor publishes one.: $0.0036 5
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.: Not published
Free tier detail What the free tier or credit includes, as published.: Not published
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.: Not published
Resume time ms Vendor-published resume-from-pause/standby/snapshot time in milliseconds.: Not published
Startup claim The vendor's startup/resume wording with conditions, quoted or closely paraphrased.: Not published
Max session length Longest single sandbox session by plan, as published.: Auto-delete up to 24 h after creation (12 h after scale-to-zero) 1
Persistence / snapshots Filesystem state can be kept between runs (snapshots, persistent disks, volumes).: Not published
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.: Yes 5
Self-host Can run on your own hardware or cluster (open source or licensed).: Not published
BYOC / VPC Vendor-managed deployment inside your own cloud account.: Not published
Open source Core sandbox runtime is published under an open-source licence.: Not published
Licence Open-source licence of the runtime, if any.: Not published
SDKs / languages Official SDK languages (or supported execution languages where noted).: Python, JavaScript 1
Regions Published regions or region count.: Not published
Max vCPU per sandbox vCPU Largest published vCPU count per sandbox on any self-serve or enterprise plan.: Not published
Max memory per sandbox GiB Largest published memory per sandbox.: Not published
Concurrency Published concurrent sandbox limits by plan.: Not published
SOC 2 SOC 2 status as stated by the vendor.: stated (type not given) 3
HIPAA Vendor offers HIPAA-compliant usage/BAA (on any plan).: Not published
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.: Not published
Status Preview, experimental, beta, sunset or self-hosting caveats the vendor documents.: Not published

Pricing note: Sandboxes (public preview) need a Starter, Pro ($29/mo + compute) or Scale ($299/mo) plan. Koyeb prices compute per bundled instance, e.g. $0.0144/h for 1 vCPU / 1 GB (small) and $0.0288/h for 2 vCPU / 2 GB (medium); the sandbox docs do not say which instance types sandboxes use, so no per-vCPU rate is listed.
