Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Formance

  • Formance holds no money and provides no regulatory cover, so it must be paired with a payments provider or bank, and buyers occasionally mistake a ledger for a treasury system and discover the gap late.
  • Numscript is a domain-specific language your team must learn, and while it makes complex splits expressible it also means transaction logic sits outside the languages your engineers already debug well.
  • Self-hosting a ledger that must never lose or duplicate a transaction is a serious operational commitment covering backups, upgrades and Postgres tuning, which is real cost the zero licence fee hides.
  • Enterprise pricing is not published, so the difference between the free path and the supported path cannot be evaluated without a sales conversation.
  • The company is much smaller than the incumbent alternatives, and while the MIT licence protects the code it does not protect the roadmap, so features on the hosted side may arrive slowly or change direction.

Puppeteer

  • Chrome and Firefox only, with no Safari or WebKit story
  • Not a test framework: assertions, retries and reporting need Jest or similar bolted on
  • Bundles a Chromium download, which makes installs large and awkward in constrained CI images

Answered from the vendors’ own pages

Formance: Is Formance really open source?

Yes. The core ledger is MIT licensed with full source access and no deployment restrictions.

Puppeteer: Is Puppeteer free?

Yes, open source from the Chrome team.

Formance: Does Formance move money?

No. It records and orchestrates movements; the actual payments happen at a PSP or bank you connect.

Puppeteer: Puppeteer or Playwright?

Playwright came from the same original team, adds WebKit and Firefox support, automatic waiting and a test runner. Puppeteer stays a focused Chrome automation library, which is simpler if automation rather than testing is the goal.

Formance: What does the enterprise version cost?

Not published. It is an annual subscription quoted per customer.

Puppeteer: Can Puppeteer generate PDFs?

Yes, and it is one of the most common uses — rendering a page and printing it to PDF server-side.

Formance: Do I have to use Numscript?

Yes for anything beyond the simplest transfers. It is how multi-party transactions are expressed atomically.
