# NimbusNexus > A cloud platform for VMs, managed databases, and storage, plus developer > services — managed webhook delivery and disposable email addresses for > testing. Transparent per-second / per-GB pricing, four regions (Virginia, > Los Angeles, Frankfurt, Singapore), 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; three block storage tiers with live resize; S3-compatible object storage; 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; 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. Full text of every docs page in a single response: https://www.nimbusnexus.net/llms-full.txt ## 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): three NVMe tiers (Standard, Performance, Extreme), live resize, snapshots, cross-region replication. - [Object storage](https://www.nimbusnexus.net/object-storage): S3-compatible buckets with Standard / IA / Cold storage classes. - [Cold storage](https://www.nimbusnexus.net/cold-storage): archive tier with three retrieval classes (Expedited, Standard, Bulk). - [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, publishing stops at the cap rather than being billed as overage. Starter is $29/month (500,000 events) and Pro is $149/month; the fourth tier is Custom, priced by contract. 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. - [Mosaic editor](https://www.nimbusnexus.net/products/mosaic): browser-based YAML / JSON / Markdown editor for S3-compatible 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. ## Free tools A collection of single-purpose utilities. Everything runs in the user's browser and is free; no account or sign-up required.

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 `Authorization: Bearer` request shape, scope model, project boundaries, key rotation, and the canonical error codes for auth failures. - [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): geographic locations NimbusNexus serves, live + pre-launch status. - [Virtual machines](https://www.nimbusnexus.net/docs/api/vms): provision, inspect, resize, and destroy compute instances. - [Managed databases](https://www.nimbusnexus.net/docs/api/managed-databases): Postgres, MySQL, MongoDB, Redis, Kafka, OpenSearch — provision, snapshot, restore. - [Block storage](https://www.nimbusnexus.net/docs/api/block-storage): NVMe volumes attached to VMs. Three tiers, live resize, snapshots. - [Object storage](https://www.nimbusnexus.net/docs/api/object-storage): S3-compatible buckets with three storage classes and free in-region transfer to VMs. ### 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. ## Reference - [Pricing](https://www.nimbusnexus.net/pricing): full price catalog with interactive calculators for VMs and storage. - [Marketplace](https://www.nimbusnexus.net/marketplace): one-click app stack deployments (n8n, Plausible, Mattermost, GitLab, etc.). - [Changelog](https://www.nimbusnexus.net/changelog): release notes for the platform. - [Changelog RSS feed](https://www.nimbusnexus.net/changelog/feed.xml): RSS 2.0 feed of the most recent changelog entries. ## Resources - [Resources hub](https://www.nimbusnexus.net/resources): articles, guides, and architecture playbooks. ### Architecture playbooks - [VM families explained: gp, co, mo, gx](https://www.nimbusnexus.net/resources/vm-families-explained-gp-co-mo-gx): what each VM family is for, with concrete workloads and resize patterns. - [Postgres, MySQL, MongoDB, Redis: when to reach for which one](https://www.nimbusnexus.net/resources/postgres-mysql-mongo-redis-when-to-use): honest decision guide for the four databases most teams actually run. - [A logistics platform on NimbusNexus, region by region](https://www.nimbusnexus.net/resources/architecture-logistics-supply-chain): hypothetical architecture for an APAC freight platform — Singapore primary, Frankfurt for EU receivers. - [Low-latency game servers on Los Angeles + global edge](https://www.nimbusnexus.net/resources/architecture-gaming-low-latency): real-time multiplayer game architecture with co-* dedicated cores and Redis matchmaking. - [Blockchain node hosting in Frankfurt with EU compliance built in](https://www.nimbusnexus.net/resources/architecture-blockchain-node-hosting): validator and full-node fleet design with GDPR / BaFin posture. - [An LLM inference fleet on Virginia, autoscaled by the second](https://www.nimbusnexus.net/resources/architecture-llm-inference-fleet): GPU inference architecture with L4 / H100 fleets and a pgvector control plane. ### Developer guides - [From git push to running container in under a minute](https://www.nimbusnexus.net/resources/git-push-to-container): the CLI-first NimbusNexus workflow. - [Production workloads with SLAs your CFO will sign](https://www.nimbusnexus.net/resources/production-slas-cfo): the production / compliance half of the platform. - [Real cloud, classroom budget: the student guide to NimbusNexus](https://www.nimbusnexus.net/resources/student-credits-cloud): the student credit program and assignment patterns. ## Company - [Careers](https://www.nimbusnexus.net/careers): open engineering, product, and operations roles. - [Contact](https://www.nimbusnexus.net/contact): contact form for sales, support, security, and general inquiries. - [Support](https://www.nimbusnexus.net/contact/support): support contact. ## Legal - [Privacy Policy](https://www.nimbusnexus.net/privacy-policy) - [Terms of Service](https://www.nimbusnexus.net/terms-of-service) - [Acceptable Use Policy](https://www.nimbusnexus.net/acceptable-use-policy) - [Data Processing Addendum (DPA)](https://www.nimbusnexus.net/dpa) - [Service Level Agreement](https://www.nimbusnexus.net/service-level-agreement) - [Sub-processors](https://www.nimbusnexus.net/sub-processors) ## Optional - [Sitemap](https://www.nimbusnexus.net/sitemap.xml): full canonical URL list per locale, including dynamic article and changelog entries. - [AI policy](https://www.nimbusnexus.net/ai.txt): crawler rules and content licensing for AI systems. - [Robots](https://www.nimbusnexus.net/robots.txt): standard robots directives.
