One mojojojo credit is $0.001 and buys milliseconds here.

Persistent services · limited preview

Reserve a continuously running Python or Mojo process for WebSockets, warm models, custom servers, and in-memory indexes. Reserved capacity is billed while idle; normal scale-to-zero functions remain the economical default for bursty traffic.

Profile	Reserved resources	Rate	Approx. 30 days if never stopped
CPU nano	0.25 shared CPU · 512 MiB	200 credits · $0.20/hour	$144
CPU 1	1 CPU · 2 GiB	750 credits · $0.75/hour	$540
CPU 2	2 CPU · 4 GiB	1,400 credits · $1.40/hour	$1,008
GPU 24	4 CPU · 16 GiB · 24 GiB GPU	3,500 credits · $3.50/hour	$2,520

Charged hourly in advance and cancelled at the next renewal. Failed builds are free. Billing pauses if reserved capacity is unavailable. Execution inside the reserved profile is included; storage above the included allowance remains separately metered.

Managed vector search

Durable vector projects with exact and performance search behind one API.

Exact CPU · $0.50

per 1,000 queries

Predictable exact retrieval with no idle fee.

GPU performance · $1.50

per 1,000 queries

Accelerated search for larger collections.

$0.02 / 1,000 upserts

250,000 documents per project

Batch upserts, metadata, durable documents, and API access included.

Shared usage is metered against the same credits as compute. Reserved capacity can be managed from the Vector dashboard.

Managed JSON data

10 databases included

Tenant-isolated Postgres JSONB namespaces with API-key and session access.

10,000 records each

Up to 64 KiB per JSON value and 100 MiB total per database on the shared tier.

Optional vector link

Search text uses normal vector upsert/query rates; storing and reading JSON has no execution charge.

The shared data preview has no idle-instance fee. Dedicated Postgres will be a separate tier when workloads need SQL connections, extensions, or stronger isolation.

Object storage and site delivery

1 GB included

Per account, for deployed sites, models, and user-uploaded assets.

$0.05 / GB-month

Only storage above the included gigabyte. Usage is visible in Cloud.

Delivery included

Public assets are served from mojojojo's global static domain with no delivery surcharge.

What is not billed

Cold start

The clock starts when your program starts. Interpreter startup, the sandbox, and the process fork are ours. Warm slots make it about 60ms end to end anyway.

Installing packages

Your imports are read out of your code and installed by uv into a cached environment. First time for a package set: a second or two. Billed: nothing.

Our compiler

Transpiling your kernels to Mojo and compiling them happens on our machines, on our clock, after your run has returned.

Free credits

Every new mojojojo account gets 1000 credits — $1 of compute the first time it runs something here. No card, no trial clock. At the CPU rate that is nearly three core-hours, which is a lot of backtests.

One grant per account, ever. Server-side runs need an account for exactly this reason: free compute behind an anonymous endpoint is free compute per request, and it would be strip-mined within a day. The browser runtime needs no account because it costs us nothing.

Worked examples

Job	Time	Cost
A 40ms data transform, called 1000 times	40 s	4 credits — $0.004
A backtest that takes 3 s (native, after the first run)	3 s	0.3 credits — $0.0003
An hour of continuous CPU work	60 min	360 credits — $0.36
Ten minutes of GPU	10 min	300 credits — $0.30

Sub-credit runs are not rounded up. Milliseconds accrue against your balance and a credit moves when they cross the rate, so a thousand 40ms calls cost the same as one 40-second call.

Capacity that follows demand

Capacity expands as paid demand grows. The prices above do not change, and queue time is never billed.
