What is Bigcapital?
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.
What is Fathom?
Fathom keeps deepening consolidations and forecasting, but half its feed is scraped marketing pages.
Fathom is a financial analysis, management-reporting, and cash-flow forecasting tool (part of The Access Group) aimed at accountants and advisors, with consolidated reporting as its center of gravity. The genuine changelog entries show steady, focused work: division-level consolidated financials and a batch of forecasting usability gains. Much of the feed, however, is crawl noise, customer-story pages and scraped 'what's new' listing pages ingested as if they were releases.

◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Fathom
2.5FINANCE
Fathom keeps deepening consolidations and forecasting, but half its feed is scraped marketing pages.
◆ Current state
Fathom is a financial analysis, management-reporting, and cash-flow forecasting tool (part of The Access Group) aimed at accountants and advisors, with consolidated reporting as its center of gravity. The genuine changelog entries show steady, focused work: division-level consolidated financials and a batch of forecasting usability gains. Much of the feed, however, is crawl noise, customer-story pages and scraped 'what's new' listing pages ingested as if they were releases.
◆ Where it's heading
Real product effort concentrates in two areas: deeper consolidated reporting, now able to analyze performance across divisions within a group, and forecasting usability, with bulk driver actions, a higher microforecast limit, and a more interactive cash-flow grid. The direction is incremental depth in the reporting and forecasting core rather than any new capability surface.
◆ Prediction
Expect continued incremental deepening of consolidation and forecasting, more grouping options and forecasting controls, rather than a directional move. Separately, the crawl source needs attention: customer stories and listing pages are polluting the changelog.
