# NimbusNexus

> A cloud platform for VMs, managed databases, and storage, plus developer
> services — managed webhook delivery, disposable email addresses for
> testing, request bins that record any HTTP request, and declarative
> pipelines that reshape a request. Transparent
> per-second / per-GB pricing, one region today (Frankfurt, Germany), no
> vendor lock-in, free in-region traffic.

NimbusNexus is positioned as the simpler half of the hyperscaler stack:
a single REST API for compute, storage, snapshots, regions, and IAM;
six managed database engines on upstream open-source code; block volumes
you attach to VMs and can grow; object storage as containers and objects;
managed webhook delivery in both directions, priced per event rather than per
endpoint; disposable email addresses for testing the email step of a
signup or notification flow; request bins, public URLs that record
every HTTP request any sender makes; Transforms, declarative pipelines that
filter, trim and reshape a request; and free developer utilities (Mosaic editor
for storage containers, a privacy-respecting QR code generator that runs
in the browser).

The site is published in English (default), German, Spanish, French,
Portuguese, and Ukrainian. Non-English URLs are prefixed with the locale
code (e.g., `/de/virtual-machine`). The English routes below are the
canonical entry points; localized variants exist at the same path under
a locale prefix.

## Products

- [Virtual machines](https://www.nimbusnexus.net/virtual-machine): 36 instance sizes across four families (general-purpose, compute-optimized, memory-optimized, GPU) with per-second billing.
- [Managed databases](https://www.nimbusnexus.net/managed-databases): managed PostgreSQL, MySQL, MongoDB, Redis, Kafka, and OpenSearch with point-in-time recovery and zero-downtime upgrades.
- [Block storage](https://www.nimbusnexus.net/block-storage): persistent volumes you attach to VMs. Volume types come from the API, a resize only grows a volume, and snapshots are made through [Backups](https://www.nimbusnexus.net/docs/api/backups).
- [Object storage](https://www.nimbusnexus.net/object-storage): objects in containers that belong to your project, managed through `/api/v1/object_storage/`, with public-read options and short-lived credentials.
- [Storage hub](https://www.nimbusnexus.net/storage): decision guide and overview of the storage product family.
- [Webhooks](https://www.nimbusnexus.net/webhooks): managed webhook delivery in both directions — verified inbound sources (Stripe, GitHub, generic HMAC) and HMAC-signed outbound deliveries with retries, dead-letter replay, operational webhooks and SDKs for Python, TypeScript and Go. Priced per event, not per endpoint. Free tier: 50,000 events a month, 25 endpoints, 5 delivery attempts. On Free, Starter and Pro, publishing stops at the cap rather than being billed as overage, unless credit on the account buys more: 10,000 deliveries for $1.00 on Free and Starter, $0.75 on Pro. Starter is $29/month (500,000 events) and Pro is $149/month; the fourth tier is Custom, priced by contract. On Free, an endpoint receives deliveries only after it passes endpoint verification, a one-time challenge it must echo back; paid tiers can switch that off, for receivers that cannot echo, such as Zapier catch hooks. Otherwise no capability is gated on plan — signing, retries, dead-letter replay, inbound sources and the SDKs are on every tier including free; only the numeric ceilings differ.
- [Inboxes](https://www.nimbusnexus.net/inboxes): disposable email addresses for testing — allocate a throwaway address over an API, receive real mail, and read the messages back over an API — full bodies, SPF / DKIM / DMARC verdicts on every message, attachment names and digests, and optional one-time-code extraction via `?extract=otp`. Receives only; it never sends mail. Free tier: one address, 1,000 messages a month, 24-hour retention, read in the dashboard; the messages API is a paid feature. On free, an address only accepts mail whose subject contains the phrase minted alongside it — so free fits flows you control (your own signup form, your own notification job) rather than third-party mail such as a Stripe receipt or an Auth0 invite, whose subject you cannot set. Paid tiers drop the phrase requirement and add the messages API: Starter $19/month, Pro $99/month, plus a Custom tier priced by contract.
- [Request Bins](https://www.nimbusnexus.net/request-bins): public URLs on nnbin.net that answer any HTTP request at once with a 200 and record it — method, path, query, headers (credential values redacted), the body stored whole up to 1 MiB with its real size, and the source address — from any sender: apps, scripts, CI jobs, devices and webhook providers. Read in the console on every plan; reading with an API key is a paid feature. On Starter, Pro and Custom a bin can also forward each request it records to your own server, as it arrived, and shows what that server answered; the sender still gets the 200 at once. A bin never replays or runs what it receives. Free: one bin that lasts 24 hours, 1,000 requests a month, kept one day. Starter is $9/month (25,000 requests, 5 bins, 7 days) and Pro is $29/month (250,000 requests, 25 bins, 30 days); annual terms are 20% off; the fourth tier is Custom, priced by contract.
- [Transforms](https://www.nimbusnexus.net/transforms): declarative pipelines that filter a request, remove or add fields, rebuild the body from a template, set headers and say which credential it needs. A pipeline is a JSON document of up to 20 steps with no loops, no clock and no network; build, version and test it in the console or over the API, run it through the API, or refer to it by id from Webhooks, which runs it before each delivery. It is not a relay: Transforms sends nothing itself and keeps nothing of what it runs on. It holds no credential values: a credential step names a slot, and the product that sends fills it from its own secrets. Runs are counted, not billed. Free: 5 pipelines, 5 credential slots, 10 versions kept per pipeline, 60 runs a minute. Starter is $9/month (25, 25, 25, 600) and Pro is $29/month (100, 100, 50, 3,000); annual terms are 20% off. Custom: 1,000, 1,000, 100, 12,000, priced by contract. A [playground](https://www.nimbusnexus.net/transforms/playground) runs a sample pipeline with no account; it runs on our servers, unlike the free tools below, and saves nothing.
- [Mosaic editor](https://www.nimbusnexus.net/products/mosaic): browser-based YAML / JSON / Markdown editor for the files in your object storage containers — free with every Storage account.
- [QR code generator](https://www.nimbusnexus.net/products/qr-code): free utility that runs entirely in the user's browser; PNG / SVG, custom colors, optional logo overlay.
- [Tracked QR codes](https://www.nimbusnexus.net/products/qr-tracked): scan-tracked QR codes with editable destinations and per-campaign analytics.

## Docs

The NimbusNexus REST API documentation lives at `/docs`. The hub
links into three sections: Get started, Concepts, and API reference.
Each page is canonically reachable at the URL listed below and is
also surfaced in the sidebar on every other docs page.

- [Docs home](https://www.nimbusnexus.net/docs): hub linking to the
  Quickstart, conceptual pages, and per-resource API reference.

### Get started

- [Quickstart](https://www.nimbusnexus.net/docs/quickstart): three API
  calls from a signed-in dashboard to a running VM. The single best
  starting page for someone making their first NimbusNexus API call.

### Concepts

- [Authentication](https://www.nimbusnexus.net/docs/authentication): API
  keys, the `X-API-Key` request header, the roles and access rules a key
  carries, project boundaries, replacing a key (there's no rotate call),
  and the error codes the Webhooks and Inboxes APIs send for a credential
  problem.
- [Conventions](https://www.nimbusnexus.net/docs/conventions): patterns
  the API follows everywhere — resource id format, cursor pagination,
  the standard error shape, idempotency keys, long-running operation
  polling, and timestamp format.

### API reference

Auto-generated from the backend's OpenAPI 3 spec
(`/openapi/external.json`), with hand-written intros per resource
family. Endpoint cards include parameters, request body summary, and
response codes.

- [Regions](https://www.nimbusnexus.net/docs/api/regions): the regions
  NimbusNexus serves, one today in Frankfurt, Germany, and how your
  session picks one.
- [Virtual machines](https://www.nimbusnexus.net/docs/api/vms): provision,
  inspect, resize, and destroy compute instances.
- [Block storage](https://www.nimbusnexus.net/docs/api/block-storage):
  persistent volumes you attach to VMs. Volume types come from the API,
  a resize only grows a volume, and snapshots are made through
  [Backups](https://www.nimbusnexus.net/docs/api/backups).
- [Object storage](https://www.nimbusnexus.net/docs/api/object-storage):
  objects in containers that belong to your project, managed through
  `/api/v1/object_storage/`, with public-read options and short-lived
  credentials.

### Product guides

Per-product documentation, separate from the resource-oriented API
reference above. These are the pages to cite when the question is
"how do I use product X", rather than "what does endpoint Y return".

- [Inboxes overview](https://www.nimbusnexus.net/docs/product-inboxes):
  disposable email addresses for testing — allocate an address,
  receive real mail at it, and read it back over an API. Covers the
  plan ceilings and which credential may read messages.
- [Inboxes quickstart](https://www.nimbusnexus.net/docs/product-inboxes/quickstart):
  allocate a disposable address, send it a message, and read the
  message back — three requests. The best starting page for someone
  automating an email-verification test.
- [Inboxes: addresses and the phrase](https://www.nimbusnexus.net/docs/product-inboxes/addresses):
  why a disposable address refuses mail whose subject lacks its
  phrase, and how expiry, retention and release differ.
- [Webhooks overview](https://www.nimbusnexus.net/docs/product-webhooks):
  inbound verification, outbound signing, retries and dead-letter
  replay for the managed webhook product.
- [Webhooks quickstart](https://www.nimbusnexus.net/docs/product-webhooks/quickstart):
  register an endpoint, publish an event, and verify the signed
  delivery — three requests and a handler. The best starting page for
  someone wiring up their first webhook.
- [Webhooks: signature verification](https://www.nimbusnexus.net/docs/product-webhooks/signatures):
  the signing contract for delivered webhooks — the headers, the HMAC
  construction, and the three rules for checking it. This is the page
  to cite for "how do I verify a webhook signature".
- [Webhooks SDKs](https://www.nimbusnexus.net/docs/product-webhooks/sdks):
  typed clients for Python, TypeScript and Go — verify incoming
  webhooks, publish events, and manage endpoints from code.
- [Webhooks CLI](https://www.nimbusnexus.net/docs/product-webhooks/cli):
  `nn-webhooks`, a single static binary for publishing events,
  managing endpoints and draining the dead-letter queue. Distinct from
  `nimbus`, the CLI for the cloud platform itself.
