What Invoice Ninja actually is
Invoice Ninja is an open-source invoicing and billing application. You can run it two ways: self-host the open-source code on your own server for free, or use the hosted cloud version, which has a free tier with limits and paid plans that unlock more clients, branding control and automation features.
It is a genuinely strong product. It does recurring invoices, online payment gateways, client portals, time tracking, expenses, project billing and automation workflows, and because it is open source you can modify it and own your data outright when self-hosted. That makes it a great fit for technically comfortable users and small agencies who want control and are happy to maintain a server, or to pay for a plan that lifts the free-tier ceilings.
The honest trade-offs
The power comes with two costs, depending on how you run it. Self-hosting is free but not effortless: you provision a server, install the application and its database, configure mail and payment keys, keep it updated, and handle backups and security yourself. That is fine if you enjoy it or already run infrastructure, and a real chore if you just want to bill a client this afternoon.
The hosted cloud version removes the setup but the free tier carries limits, and lifting them moves you onto a paid plan. Neither path is wrong; they simply suit people who want either full control (self-host) or a feature-rich billing suite they will pay for (cloud). If your actual need is narrower, sending a clean, compliant invoice now, both paths ask more of you than necessary.
FreeBillGen vs. Invoice Ninja at a glance
Both tools create invoices well. They differ mainly in how you run them and how far the free option stretches. The table below is a fair, factual comparison.
| Aspect | FreeBillGen | Invoice Ninja |
|---|---|---|
| Hosting model | Hosted, zero setup | Self-host or cloud |
| Setup effort | None, open and go | Server setup (self-host) |
| Free tier | Free core forever, unlimited | Free self-host; cloud free tier has limits |
| Card required | No card | Card for paid cloud plans |
| Watermark on free output | None | None |
| Languages | 80 languages | Many, fewer than 80 |
| EU VAT & reverse charge | Built in | Configurable |
| Recurring & automation | Limited | Yes, extensive |
| Online payment gateways | No | Yes |
| Open source / self-host | No | Yes |
| Data ownership | Single LT controller, GDPR | Yours when self-hosted |
Read it as fit, not a verdict. Invoice Ninja wins on automation, payment gateways and the option to self-host and own everything. FreeBillGen wins on zero setup, an always-free unlimited core, and 80-language EU VAT invoicing for people who do not want to run software.
Where FreeBillGen fits
FreeBillGen is a hosted invoice generator with nothing to install. You open it in a browser, enter your business and client details, add line items and tax, and download a clean PDF. The core is free forever with unlimited invoices, no watermark and no card, and it ships with 80 languages so you can bill across borders in the client’s language and currency.
For tax, it covers what an invoice needs: EU VAT at the correct rate and reverse-charge wording for cross-border EU B2B supplies, with a clear payable total. Data sits with a single data controller in Lithuania under GDPR, and there are no third-party trackers, so you get the privacy posture of a self-hosted app without having to run one.
What it does not try to be is a full billing suite. There is no client portal, no built-in payment gateway, and only limited recurring and automation features. If you need those, Invoice Ninja (self-hosted or on a paid plan) is the better tool, and that is an honest recommendation. For the common case, send a professional invoice today without standing up a server or watching a plan limit, the free hosted generator is the faster path. An optional Pro tier adds multi-company support, a write API and accounting export for those who outgrow the basics.
How to choose between them
Pick based on what you actually do. If you want recurring billing, payment links, a client portal and automation, and you are happy to either run a server or pay for cloud, Invoice Ninja is built for that and is a solid choice. If you want to own and modify the software end to end, its open-source self-host path is exactly right.
If you simply need to issue correct, good-looking invoices now, in many languages, with EU VAT handled, and you do not want any setup, cost or plan ceiling, start with FreeBillGen. You can test the fit in minutes with no commitment: open it, make one invoice, and download the PDF. Because the invoices are standard files you own and an optional accounting export exists, moving on later is never a trap.
Invoice Ninja alternative questions
Is there a free alternative to Invoice Ninja with no setup?
Yes. FreeBillGen is a hosted, zero-setup free alternative: you open it in a browser, create an invoice and download the PDF, with no server to maintain and no plan limit on the free core. Invoice Ninja is also free if you self-host, but that requires running and updating your own server.
What is the difference between FreeBillGen and Invoice Ninja?
FreeBillGen is a hosted invoice generator focused on quickly producing compliant invoices with no setup, and its core is free forever. Invoice Ninja is an open-source billing app you can self-host for free or use on a paid cloud plan; it adds recurring billing, payment gateways and a client portal, in exchange for hosting effort or a subscription.
Is Invoice Ninja free?
Invoice Ninja is free if you self-host the open-source version on your own server, and it offers a free cloud tier with limits plus paid cloud plans that unlock more. So it is free in two senses with different trade-offs: free but self-managed, or hosted but limited until you pay. FreeBillGen keeps its hosted core free and unlimited.
Do I need to self-host to use FreeBillGen?
No. FreeBillGen is fully hosted, so there is nothing to install, configure or maintain. You use it in your browser and your data sits with a single data controller in Lithuania under GDPR. If you specifically want to self-host and own the codebase, Invoice Ninja is the better choice for that.
Does FreeBillGen support EU VAT and multiple languages like Invoice Ninja?
Yes. FreeBillGen applies the correct EU VAT rate, supports reverse-charge wording for cross-border EU B2B supplies, and ships with 80 languages out of the box. Invoice Ninja also handles VAT and many languages but is configurable rather than preset, and supports fewer languages than 80.
Which should I choose for recurring invoices and online payments?
For recurring billing, payment gateways, 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 built-in payment gateway, so it is best when you mainly need to send compliant one-off invoices quickly and for free.
