Simple, Transparent Pricing

Monthly subscriptions with credits included. Add more anytime with credit packs. Pay only for what you use.

Choose Your Plan

Every plan includes credits for compute, storage, and operations. Paid tiers add a monthly credit allowance; Free includes a one-time starter balance.

One Credit Balance, All Services

Credits are the single unit across all KernStack services. No per-service billing, no surprises.

Monthly Allocation

Your subscription credits are allocated at the start of each billing month and shared across all services — Functions, Tables, Buckets, and Search.

One-Month Rollover

Unused subscription credits roll over into the next month, but only for one month. Your balance is at most two months of credits.

Automatic Deduction

Credits are deducted automatically from metered compute (GiB-seconds: mebibytes of allocation ÷ 1024, times wall-clock seconds), storage (GB-hours), and network egress only (ingress is free; GiB: bytes ÷ 1024³). Subscription credits are consumed first, then top-up credits.

Graceful Exhaustion

If your balance reaches zero, new requests are throttled — not terminated. Upgrade, top up, or wait for the next billing cycle. Your data is never deleted.

Price Reference

We map billable work across the stack to the same three primitives — compute, storage, and network egress — so usage is expressed in a single internal model that mirrors real resources instead of a separate fee per product surface.

Base usage rates
Dimension Rate (credits)
Compute 0.01 / GB-second
Storage (Tables, Buckets, Search index storage, etc.) 0.04 / GB-hour
Network egress 9.00 / GiB

For duration-metered usage, your bill is compute + storage + egress at the rates above, summed and rounded up to a whole credit. Compute uses (RAM in mebibytes ÷ 1024) × wall-clock seconds — GiB-seconds — × the compute rate; the table label “GB-second” is shorthand. Network is egress only (ingress is free): bytes ÷ 1024³ to GiB, × the egress rate.

Model API (system catalog)
Model Unit Batch Credits
text-embed-v1 Tokens 1,000 3
sentiment-multilingual-v1 Tokens 1,000 2
face-detect-v1 Images 1 3
label-detect-v1 Images 1 3
text-detect-v1 Images 1 3
moderation-v1 Images 1 3
image-quality-v1 Images 1 3

Each catalog model charges in steps: count prompt_tokens in chunks of 1,000, or one step per images. Each step uses fixed compute and egress assumptions at the rates above (rounded up). Total = steps × the per-step credits in the table (e.g. 2,500 sentiment tokens → 3 steps × 2 = 6 credits).

Custom inference (non-catalog invoke) uses wall-clock time, endpoint memory, and response size as egress — same compute + egress formula as other metered APIs.

Credit Use Scenarios

Rounded monthly examples mixing compute, storage, egress, search, and some catalog model usage. Real usage varies.

Default mobile app backend

Typical REST + auth, profiles and feeds, light background jobs and push hooks.

  • Compute (~113k GiB-s APIs, workers, scheduled tasks)~1,130
  • Storage (~10 GB average month)~292
  • Egress (~15 GiB JSON and presigned media to clients)~135
  • Search (read-lean index and queries)~293

Approx. total~1.9k cr

Mid-tier B2B SaaS

Predictable API and worker load, shared tables and search, with selective catalog models for text and vision.

  • Compute (~480k GiB-s APIs, queues, cron)~4,800
  • Storage (~38 GB average month)~1,110
  • Egress (~48 GiB to browsers and partners)~430
  • Search (reindex churn + query compute)~1,250
  • Model API (mixed text + vision, unit usage from catalog)~472

Approx. total~8.1k cr

Popular mobile/web backend

Higher RPS, heavier search and recommendations, bursts of generative media — often a subscription plus top-up packs.

  • Compute (~1.35M GiB-s edge + core services)~13,500
  • Storage (~195 GB average month)~5,700
  • Egress (~400 GiB CDN and client pulls)~3,600
  • Search (large corpus, frequent queries)~3,100
  • Model API (higher volume text + vision)~2,750

Approx. total~28.7k cr
