Make the move in four steps

  1. Export from E2B

    Download your data and files before you change anything.

  2. Check what Free plan keeps

    Details

  3. Switch to Free plan

    Change the plan in E2B's billing settings before your renewal date.

  4. Check the next bill

    Your next E2B invoice should show the lower price. Check that your data and links still work.

Modeled, not measured. Savings use public prices and planning assumptions: the bill you stop paying, minus the new tool, your upkeep time and your setup time at $50/hour, over the first 12 months. Paths marked Tested by Stackcut were run end to end by us on our own products. They're our tests, not customer results. Check the must-haves in each recipe before you switch.

Cheaper planE2B free credit ($100 one-time, then usage)Savings not modeled yet
Workload-specific. A zero base fee or one-time credit does not remove recurring usage charges. Hobby: $0/mo with a $100 one-time usage credit; sessions up to 1 hour; 20 concurrent sandboxes; default CPU/RAM
Covers 100% of the core features
Trying E2B: the $100 credit is one-time, not a free plan. Once it is used, sandbox compute bills at the same per-second rates as Pro. For a lasting downgrade from Pro, the E2B Hobby right-size path prices the Hobby plan at your usage.
Porting: Measure CPU, RAM, total sandbox runtime and peak concurrency. Verify whether Pro-only capabilities are needed and record unused credit separately from recurring cost.

Covers 100% of the core features
Only with a platform team: a Terraform/Nomad cluster on GCP or AWS with nested virtualization, not a small server. Unpriced: total cost and isolation parity require sizing and validation; no $5/month hosting quote is established.
License: Apache-2.0
Porting: Benchmark sandbox startup, CPU/RAM/runtime/concurrency and tenant isolation. Include infrastructure, patching, monitoring, backups and operator time. Keep cost unknown until measured.
