Next.js 15, PostgreSQL and Razorpay can form a workable stack for an Indian SaaS, but it is not an automatic default for a new product in 2026. Next.js 15 is in Maintenance LTS while 16 is in Active LTS, and the right choice also depends on your server requirements, database operations, billing model and Razorpay account eligibility. Treat this as an implementation guide—not a claim that this exact combination has been tested or is the publisher’s deployed stack.
Is Next.js 15 still a sensible choice in 2026?
Yes, if you have a concrete reason to stay on it and are prepared to maintain a version in Maintenance LTS. The Next.js 15 stable release was announced on October 21, 2024. The framework’s support policy, checked on October 7, 2026, classifies 15.x as Maintenance LTS and 16.x as Active LTS. The policy encourages production applications to use the latest Active or Maintenance LTS release; it does not make 15 the current major version.
For a new project, compare the cost of adopting 16 with the cost of starting on 15 and later migrating. Existing dependencies, team experience or a migration plan may justify 15. Pin and verify the exact patch version you deploy: the available release information establishes the support status of the 15.x line, but does not identify a specific Next.js 15 patch as the one used by this application.
Account for the Next.js 15 migration behavior
The Next.js 15 upgrade guide specifies React and React DOM 19 as minimum versions for the documented upgrade path. It also makes request-related APIs asynchronous, including cookies, headers, draftMode, params and searchParams. Code that assumes these APIs return values synchronously needs to be checked and updated.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Caching defaults also changed. In Next.js 15, fetch requests, GET Route Handlers and client navigations are not cached by default. Review each route and data request for its intended freshness and caching behavior instead of carrying assumptions forward from an older version. The release announcement described 15 as stable and production-ready in 2024; that release-era statement is separate from its 2026 support classification.
Choose a PostgreSQL release and operating model
PostgreSQL does not need to be a particular major version to pair with Next.js; the cited documentation establishes no such requirement. As of the PostgreSQL release information checked on October 7, 2026, version 18 was current and versions 18 through 14 were supported. The latest listed minor releases were published August 13, 2026.

The PostgreSQL project’s versioning policy provides five years of support for a major version and recommends running the current minor release within the chosen major. Choose a major version only after checking that your hosting service offers it and that required extensions and application dependencies support it. Record the actual major and minor version in your deployment documentation, and decide who owns patching, backups, restore tests and major-version upgrades.

Deploy Next.js where its server features can run
Next.js 15 can run as a Node.js server or in a Docker container. Static export is an option only when the application’s needs fit its limitations: server-dependent features have limited support in a static deployment. Provider adapters may also vary in which platform features they support, so check the adapter and hosting platform rather than assuming every Next.js capability behaves identically everywhere.

For a SaaS that needs server-side access to PostgreSQL and payment workflows, select a deployment form that supports those server responsibilities. Before committing, verify how the chosen host handles environment variables and secrets, server execution, database connectivity and deployment-specific features your application relies on. These are compatibility checks for your implementation, not guarantees supplied by the framework’s deployment options.
Set up Razorpay checkout and recurring billing
Razorpay’s Web Standard Checkout documentation lists availability in India, Malaysia, Singapore and the United States. A listed market is not a guarantee that a particular business is eligible or that its account will be activated. Confirm eligibility and account configuration with Razorpay before designing a launch around it.

Start with the documented checkout flow
- Create a Razorpay account and generate API keys for the integration.
- Build and test the checkout flow with test credentials before accepting real payments.
- When the account and integration are ready for live payments, replace test credentials with Live Mode API keys.
Standard Checkout is the more managed web checkout path described in the documentation. Custom Checkout offers more control but is described as more complex and requiring development resources. Choose it only when the product needs that control and the team can implement and maintain the additional checkout work.
Keep payment state on the server and reconcile events
Do not treat a browser redirect or client-side message as the authoritative record of a payment. Use server-side processing to establish and update the application’s payment state. Razorpay’s webhook guide specifies an HMAC-SHA256 signature based on the webhook secret and the raw request body. Verify the signature before processing the event; do not parse or cast the body first.

Webhook delivery needs to be safe under retries and irregular ordering. Razorpay identifies each event with x-razorpay-event-id, which can be used to detect duplicate deliveries, and warns that event order is not guaranteed. Persist processed event IDs or implement equivalent idempotency, and make state transitions resilient to events arriving more than once or out of sequence. Reconcile the state your system has recorded instead of assuming, for example, that an authorization event will always arrive before a capture event.
Choose the recurring-payment model that fits the product
Razorpay describes Subscriptions as plan-based recurring payments with a defined schedule and automatic charges. Its documentation covers plans, trials, retries and lifecycle operations, and lists cards, UPI AutoPay and e-mandate. Confirm the current payment-method limits and account configuration for the merchant before planning a live rollout.
Recurring Payments are a different model: the merchant controls when repeat charges are initiated, using tokens and its own business logic. Prefer Subscriptions when the product maps to scheduled plans and the supported setup fits. Consider Recurring Payments when the business needs to control charge timing and can own the associated logic. These descriptions explain the documented product models; they do not establish which methods will be enabled for a particular account.
