What is Finch?
Finch is doing the unglamorous payroll-API depth work — provider coverage, schema completeness, sandbox fidelity.
Finch is shipping plumbing across its provider network and data model: W4 documents now reachable for Paychex, FLSA status on the employment endpoint, rehire date for QuickBooks, Square Payroll reliability fixes, 7shifts added to the Provider Network in beta. Security and trust work is showing up too — PII masking in the API Explorer and CAPTCHA on dashboard signup. Sandbox mock-data quality improvements appear repeatedly in the recent run.
What is OpenCATS?
OpenCATS ships PHP 8.4/8.5 compatibility, utf8mb4 migration, and country support in its most significant release in years.
OpenCATS delivered two major releases in quick succession: v0.11.0 brought the long-deferred PHP 8 compatibility overhaul, utf8mb4 database migration, full country support across candidates/contacts/companies/job orders, CAPTCHA for career portal applications, and the replacement of the old Google ZIP lookup with OpenStreetMap Nominatim. v0.11.1 followed with a focused security hardening pass — SQL input validation, CSV import field mapping, mass-import file handling — plus Career Portal fixes and expanded contributor documentation.

Finch
5.0HR
Finch is doing the unglamorous payroll-API depth work — provider coverage, schema completeness, sandbox fidelity.
◆ Current state
Finch is shipping plumbing across its provider network and data model: W4 documents now reachable for Paychex, FLSA status on the employment endpoint, rehire date for QuickBooks, Square Payroll reliability fixes, 7shifts added to the Provider Network in beta. Security and trust work is showing up too — PII masking in the API Explorer and CAPTCHA on dashboard signup. Sandbox mock-data quality improvements appear repeatedly in the recent run.
◆ Where it's heading
The product is in 'fill-the-grid' mode: matrix of (employment-data fields) × (payroll providers). Each release closes off another cell. The strategic theme is reducing the integration surface customers have to handle themselves — if Finch supports rehire_date on QuickBooks, downstream HR-tech buyers don't write that branch in their own code. The PII masking and CAPTCHA additions hint at SOC 2 / enterprise-readiness pressure from larger customers.
◆ Prediction
Expect more Documents-Product expansions to additional providers (the W4-to-Paychex pattern repeats well), and continued Provider Network growth focused on shift- and time-tracking systems where data overlaps with payroll. The next directional move would be more advanced write capabilities (mutating data back to providers, not just reading) — Finch's existing infra makes that a natural next step.
OpenCATS
6.3HR
OpenCATS ships PHP 8.4/8.5 compatibility, utf8mb4 migration, and country support in its most significant release in years.
◆ Current state
OpenCATS delivered two major releases in quick succession: v0.11.0 brought the long-deferred PHP 8 compatibility overhaul, utf8mb4 database migration, full country support across candidates/contacts/companies/job orders, CAPTCHA for career portal applications, and the replacement of the old Google ZIP lookup with OpenStreetMap Nominatim. v0.11.1 followed with a focused security hardening pass — SQL input validation, CSV import field mapping, mass-import file handling — plus Career Portal fixes and expanded contributor documentation.
◆ Where it's heading
OpenCATS is undergoing a systematic modernization of its technical foundation: InnoDB migration (v0.10.0), PHP 8 + utf8mb4 (v0.11.0), security hardening (v0.11.1). The project is not adding net-new capability so much as making what exists maintainable and secure enough to run in modern environments. The expanded contributing documentation and automated legacy database testing signal that maintainers are investing in the contributor pipeline.
◆ Prediction
After the modernization sprint, the next likely move is a modern email/rich text editor replacement (CKEditor 4 was pinned at the final open-source release as a placeholder) and further security audit work on endpoints that haven't been touched since the v0.9 era.
