Firefly III
Firefly III publishes nightly develop builds that carry no changelog at all
A side-by-side editorial comparison of Bigcapital and Checkout.com — release velocity, themes, recent moves, and the top alternatives to consider.
Bigcapital is rebuilding its own foundation while the accounting features tick along
Nearly every recent release is dominated by one maintainer migrating the webapp to TypeScript and tearing out Redux in favour of tanstack-query, page group by page group — landing pages, form pages, guards, constants, hooks. Running alongside it is a generated TypeScript SDK built off an OpenAPI spec, now covering reports, payment links, Stripe, Plaid, and file upload and download. Actual accounting work is thinner: bulk account activation, base-currency correctness in financial reports, localized column headers in CSV, XLSX, and PDF exports.
The public trail is documentation, not releases — scope is visible, pace is not.
Everything reaching us from Checkout.com is documentation surface rather than a changelog: support hubs, developer-resource indexes, authentication guides. What those pages do reveal is the shape of the platform — card acquiring sits alongside a Checkout Business Account for holding and moving funds, a card-issuing program, fraud detection, and identity verification. Several of the newer surfaces carry a Beta label, including EventBridge event delivery, fund spending, and the Identities suite.

This is a codebase paying down debt before it grows, not a product chasing features. The OpenAPI-generated SDK is the more consequential thread — it turns Bigcapital from an app into something with a documented API surface others can build against, and the e2e test scaffolding appearing in the latest release suggests the migration is reaching the point where regressions need catching automatically. Expect the feature pace to stay modest until the TypeScript conversion finishes.
The remaining Redux and JavaScript surfaces will likely be converted next, with SDK coverage continuing to widen behind the OpenAPI spec, since both have produced commits in every recent release.

Several of the newer surfaces carry a Beta label, including EventBridge event delivery, fund spending, and the Identities suite.
The documented surface is widening past payment acceptance into money storage, card issuance, and identity — the standard progression from processor to financial-operations platform. Enterprise plumbing is being documented in parallel: mTLS and AWS PrivateLink for private API connectivity, OAuth 2.0 access keys next to legacy secret keys, per-channel key routing. A published backward-compatibility policy that enumerates exactly which changes are considered safe reads as a platform courting integrations it expects to last years.
The Beta labels on EventBridge, Spend funds, and Identities are the clearest signal available: expect those to move toward general availability before any new category appears. What we cannot see from documentation alone is release cadence — until a changelog surfaces, timing is unknowable.
