Resilient backends
Ready-made payments and identity backends with realistic scenarios and failure modes.
Get started
Resilient backends overviewWhat a resilient backend is: your own copy of a provider's API, hosted by us or run in your own network, with the failures a vendor sandbox will not give you. Payments and identity are available today.Updated Oct 2, 2026Add providersHow to add providers for hosted backends in the Backend store: how hosted and self-hosted differ, what a provider covers, how an order is billed, the free trial per type, and how to cancel under Billing.Updated Oct 2, 2026Create a hosted backendHow to create a hosted backend: what you need first, the three fields, picking the providers it serves, deploying it, the address it answers at, and taking it offline.Updated Sep 29, 2026
Payments
Payments backend overviewWhat a payments backend does: the whole payment lifecycle with state, 3D Secure your tests can complete, hosted and redirect methods, idempotency keys, and the PSP's own response shapes.Updated Sep 29, 2026Payment scenariosDrive a payments backend by naming the payment: every decline reason, the 3D Secure triggers, what to use when there is no cardholder, and which trigger wins when several match.Updated Sep 29, 2026
Identity
Identity backend overviewWhat an identity backend does: subjects, documents, cases and the checks inside them, KYC and KYB in one API, hosted captures your tests can finish, and the provider's own report shapes.Updated Sep 29, 2026Identity scenariosDrive an identity backend by naming the subject: every refusal reason, the review, pending and hosted outcomes, what reaches a subject you did not name, and which trigger wins.Updated Sep 29, 2026
Operate
Write your own scenariosAdd scenarios of your own to a backend: where they live, which layer wins, the editor and the YAML behind it, what is validated before a save, and how to scope one.Updated Sep 29, 2026Change values with contextsReplace the values a backend returns: what a context is, when you need one, how names match at any depth, how scopes stack, and what the backend still checks at runtime.Updated Sep 29, 2026Backend activityBrowse what a backend has done: the lists each type keeps, what the columns show, searching by reference, filtering, one provider at a time, and how long records last.Updated Sep 29, 2026Pin a build versionHold a backend on one build instead of following the latest: where the control is, when pinning helps, what a build change adds or drops, and how long a build stays deployable.Updated Sep 29, 2026
Self-hosted
Self-hosted backends overviewWhat a self-hosted backend is: the same providers as a hosted one, in an image you run in your own network. Who it is for, what you get, how it is licensed and paid for, and the steps from trial to a running container.Updated Sep 29, 2026Request a self-hosted trialAsk for a free trial of a self-hosted type: who can ask, what the form asks, one trial per company, how a request is decided, and what happens when the trial ends.Updated Sep 29, 2026Buy self-hosted providersBuy the providers a self-hosted backend serves: monthly by card or yearly on invoice, what each needs, what happens after you order, and how to add providers later.Updated Sep 29, 2026Create a self-hosted backendMake a self-hosted backend under a trial or a purchase: its name, the name its image is pulled as, its providers, and what goes into its image.Updated Sep 29, 2026Build an imageBuild a self-hosted backend's image into your own registry: what a build takes, how versions work, and what can stop a build.Updated Sep 29, 2026Pull your imagePull a self-hosted image from your own registry with a credential, with docker or Kubernetes, and fetch the files that ship with it.Updated Sep 29, 2026Mirrors and air-gapped hostsPull a self-hosted image through Artifactory, Nexus or Harbor, or carry it to a host with no network.Updated Sep 29, 2026Run the imageStart a self-hosted backend with docker, compose or Kubernetes, check it answers, and change its settings or its files when you run it.Updated Sep 29, 2026Storage driversChoose where a self-hosted backend keeps its data, from memory to PostgreSQL or MongoDB, and install its schema yourself or let the backend do it.Updated Sep 29, 2026LicensesWhat a self-hosted license covers, how an image gets it, fetched or carried inside, and what to do when a new one is issued or it expires.Updated Sep 29, 2026Security reportsWhat each self-hosted image holds and what is known against it: vulnerabilities in its code and its base, what we say about each, and its components.Updated Sep 29, 2026
