How does E2B pricing work?
The value metric is sandbox runtime, metered per second and priced by machine size: '$0.000014/s' for 1 vCPU up to '$0.000112/s' for 8, with RAM and disk on their own tabs. Every plan prints '(+usage costs)' under its price, so the plans sell capacity rather than compute. Hobby gives '$100 one-time usage credit', 'Sessions up to 1 hour' and '20 concurrent sandboxes'. Pro at $150 a month moves to 'Sessions up to 24 hours', '100 concurrent sandboxes, expandable to 1,100' and 'Custom sandbox CPU and RAM'. Enterprise offers 'Multi-day and persistent sessions', 'Tens of thousands of concurrent sandboxes' and 'Custom sizes, plus BYOC deployment'. Session length and concurrency are the gates, the two limits that grow with an agent workload.
The motion is self-serve through Pro with an engineer-led Enterprise path. The hero, 'PAY FOR WHAT YOU RUN. NOTHING MORE.', sits beside '↓ CALCULATE YOUR COSTS ↓', and each card repeats 'See our cost calculator'. Small lines under the buttons say how each plan is paid: '(✓) NO CREDIT CARD REQUIRED', '(S) BILLED THROUGH STRIPE' and '($) CUSTOM DEPLOYMENT AND BILLING'. Two rows of customer logos lead to the 'WORKLOAD PRICING ESTIMATOR', a 'BOOK A CALL' form, a scrolling 'ESTIMATE YOUR MONTHLY COSTS' banner, the per-second 'PRICING GUIDE', and a closing '2B+ SANDBOXES STARTED' with 'START BUILDING' and 'TALK TO AN ENGINEER'.
Under the hood, E2B runs a platform fee plus usage, with concurrency sold as a capacity add-on. The estimator itemizes 'Usage Cost $166', 'Pro Plan Base $150' and 'Concurrency Addon $0' into 'Total Monthly $316 /mo', and the concurrency options price headroom in flat steps, 'Pro+ · 600 concurrent +$500/mo' and 'Pro++ · 1,100 concurrent +$1,000/mo'. The default estimate of 2 vCPUs for 1,000 hours comes to about $101 of vCPU time at $0.000028/s, so the rest of the $166 points to RAM billed as its own meter. 'Enterprise starts at a $2,000/mo commit, 500 concurrent included.' prints the floor of the custom tier, and 'Committed usage, custom billing' names the contract shape. Worth borrowing: the estimator that shows the bill as invoice lines, and a printed starting commitment for the sales-led tier.
What does E2B's pricing page do well?
- The hero and every card link to the cost estimator, '↓ CALCULATE YOUR COSTS ↓' and 'See our cost calculator'
- The estimator returns an itemized bill, 'Usage Cost', 'Pro Plan Base' and 'Concurrency Addon', summed into 'Total Monthly'
- 'Run Hours = total sandbox runtime.' comes with a worked example, '100 sandboxes × 10 hrs = 1,000 hrs'
- Each button carries a line on how the plan is paid: 'NO CREDIT CARD REQUIRED', 'BILLED THROUGH STRIPE', 'CUSTOM DEPLOYMENT AND BILLING'
- The sales-led tier prints its entry point: 'Enterprise starts at a $2,000/mo commit, 500 concurrent included.'
What does E2B's pricing page reveal about its pricing strategy?
- Every plan prints '(+usage costs)', so the subscription buys limits and compute is billed on the meter for all three
- Per-second rates are the same on 'Hobby / Pro', so upgrading buys session length and concurrency, not cheaper compute
- Concurrency priced in flat steps, '+$500/mo' and '+$1,000/mo', turns peak parallelism into a capacity purchase
- Hobby's '$100 one-time usage credit' is a starter grant against the same meter Pro pays, so free usage and paid usage run on one rate card
- 'Custom sizes, plus BYOC deployment' on Enterprise lets large buyers run sandboxes in their own cloud under committed usage
Learn with Orb
- ProductExperience Kit E2B's 'WORKLOAD PRICING ESTIMATOR' turns vCPUs, RAM and run hours into 'Usage Cost', 'Pro Plan Base' and 'Concurrency Addon' lines, the kind of pricing calculator Orb's Experience Kit builds from one source of pricing truth.
- DocsConfiguring plans: minimums and plan phases 'Enterprise starts at a $2,000/mo commit, 500 concurrent included.' is a commitment to a dollar amount, which Orb's docs model as a minimum that tops up the invoice when usage falls below it.
- ProductInvoicing Per-second sandbox usage, a $150 plan base and concurrency add-ons like 'Pro+ · 600 concurrent +$500/mo' land on one bill, the real-time usage detail Orb's invoicing keeps clear for customers and finance teams.

Chroma
$250/mo + usageChroma prints all four metered rates in the hero, Write at $2.50 per GiB, Storage at $0.33 per GiB per month, Query at $0.0075 per TiB and Network at $0.09 per GiB returned, then hands the reader a calculator that turns documents and queries into a $79 monthly total. Plans sit on top of the meter: Starter at $0 plus usage, Team at $250 a month plus usage with $100 in credits, and Enterprise on custom terms.
Confluent
~$385/moConfluent prices serverless Kafka on a composite meter, eCKU-hours plus data in and out per GB plus storage per GB-month, and closes its rate table with an 'Estimated Monthly Starting Cost' of $0, $385, $895 and $2,300 that turns an hourly unit into a budget number. Behind it sit two discount structures and an annual commitment that can be spent across the whole Confluent Cloud stack.
Datadog
$15/host/moDatadog publishes a rate card per product, with every billable SKU listed in a left-hand navigator from AI Credits to Workflow Automation. Infrastructure Monitoring prices per host across three host levels: Basic, set with sales, beside Pro starting at $ 15 and Enterprise at $ 23 billed annually, with on-demand rates printed beside them and allotments of containers, custom metrics and custom events attached to each paid host. The bill is the sum of the products a customer adopts, and Basic hosts let one account price noncritical workloads at their own level.
Fly.io
From $0.0030/hr (shared-cpu-1x, 256MB)Fly.io prices raw infrastructure: Machines 'Billed by the second while a Machine runs', volumes on provisioned capacity, and egress by region, with prices set per region through a selector. Support is sold as its own ladder at '$29 / mo', '$199 / mo' and 'From $2,500 / mo', compliance is a '$99/mo' add-on, and a Custom plan covers committed spend and volume discounts.
Grafana
$19/moGrafana Cloud prices on a $19 per month platform fee that carries an allowance on every product, then a usage meter chosen per product, with volume tiers that lower the marginal rate as a customer grows. The hero states the thesis, 'Send more, charge more is broken. We are changing it.', and the page backs it with an embedded calculator that draws the tier curve and a cost-reduction band under the rates. Enterprise prints its entry point: 'Starts at $25,000 / year spend commit'.
Modal
$250 + compute/moModal bills GPU, CPU, memory and storage by the second or month, and network egress at '$0.04 / GiB', with the full rate card under the promise of paying for 'just actual compute time, by the CPU cycle'. Plans are a platform fee plus that usage: Starter at $0 with $30 of monthly credits and 1 TiB of egress, Team at $250 with $100 and 10 TiB, and a custom Enterprise with 100 TiB. A worked comparison makes the serverless case on utilization, with a $3.95 GPU-hour that totals '12% lower cost' than $3 GPU-hours provisioned around the clock.
