What Invoice Ninja actually is
Invoice Ninja is a source-available invoicing and billing application under the Elastic License. You can run the self-hosted code or use its cloud service. As of this review, the official cloud free plan allows unlimited invoices for up to five clients; paid plans increase client limits and add features. The official repository says self-hosted client-facing white-label use requires a separately priced license.
Invoice Ninja includes recurring invoices, payment gateways, a client portal, time tracking, expenses, project billing and automation. Self-hosting gives you control over the installation and stored data, but you are responsible for server maintenance, backups, mail and security. The cloud plans move that work to Invoice Ninja. Review its current pricing and Elastic License terms before choosing a deployment or modification.
The honest trade-offs
Self-hosting avoids a cloud subscription but still carries infrastructure and license considerations. You provision a server, install the application and database, configure mail and payment keys, keep the stack updated, and handle backups and security. Check whether the Elastic License and optional white-label license permit the way you intend to use or modify it.
The hosted cloud version removes server setup. Its free plan has a five-client limit, while paid plans expand limits and features. Neither route is inherently better: choose self-hosting when you can operate the service and its license fits, or cloud when you want Invoice Ninja to manage the infrastructure.

Where FreeBillGen fits
FreeBillGen is a hosted invoice generator with no server to install. Enter the parties, line items and tax treatment, then download a PDF. The free core includes unlimited invoices and clients, no watermark, no card, and 80 selectable options for invoice labels. Some guidance may remain in English until it is reviewed.
Tax is configurable, with supported VAT and reverse-charge fields. A named EU company operates the service, its Privacy Policy discloses external providers and roles, and it uses no advertising or behavioral analytics.
FreeBillGen has no client portal or integrated payment gateway. It can display an IBAN, an eligible SEPA QR code and an issuer-supplied Pay now URL, but does not process the payment. Invoice Ninja is the stronger fit for self-hosting, a client portal, payment-gateway integrations and broader automation. Lifetime Pro - €49 once, tax included, with no monthly or annual renewal - adds multiple companies, the write API and outbound webhooks, Xero/QuickBooks export formats, and auto-send on recurring schedules. Optional metered third-party services are not included; when offered, they use separate one-time credits that do not renew.
How to choose between them
Pick based on the work you need. Invoice Ninja is the stronger fit for a client portal, payment-gateway integrations and broader billing automation. Its self-host route suits teams prepared to operate the infrastructure and follow the Elastic License; its cloud plans suit teams that want Invoice Ninja to manage the service.
FreeBillGen is narrower: it creates invoice documents with configurable tax fields and 80 selectable options for invoice labels, without a server or client cap in the free core. Test the actual PDF, tax treatment, exports and privacy workflow before deciding. Lifetime Pro accounting-file exports are not automatic migration or two-way sync.

Is Invoice Ninja free?
Invoice Ninja publishes source-available self-hosted code and offers a cloud free plan. At this review, the cloud free plan allows unlimited invoices for up to five clients. Paid cloud plans and optional self-host white-label licensing change limits or branding. Check the current pricing and Elastic License terms before deciding.
Do I need to self-host to use FreeBillGen?
No. FreeBillGen is hosted, so there is no server to install or maintain. A named EU company operates the service and its Privacy Policy identifies provider roles. If you want to self-host Invoice Ninja or modify its code, review the infrastructure work and Elastic License first.
Does FreeBillGen support EU VAT and multiple languages like Invoice Ninja?

Which should I choose for recurring invoices and online payments?
For recurring billing, a full payment-gateway suite, a client portal and automation, Invoice Ninja is the stronger fit, whether self-hosted or on a paid plan. FreeBillGen has only limited recurring features and no mandatory payments tie-in. It can display bank details or a Pay now link to a hosted payment URL supplied by the issuer, but FreeBillGen does not process or settle the payment, so it is best when you mainly need to send professional one-time invoices quickly and for free.
