What is Bullhorn?

Bullhorn's feed is labor-market research and SMB advice, not release notes

The current entries are market reporting and how-to content aimed at small staffing firms: monthly job-opening and hiring-order analyses, an argument that SMB data problems are smaller than firms assume, an ATS buyer's guide, and now two consecutive posts on whether and how a small agency should run an applicant tracking system. The recruiting data is Bullhorn's own — GRID survey figures and order and fill-rate trends — which gives it more substance than typical vendor content, but none of it describes the product changing.

What is OpenCATS?

OpenCATS breaks a two-year quiet with v0.10.0, tightening attachment auth and form UX

OpenCATS, an open-source applicant-tracking system, ships rarely — its release history spans 2020 to 2026 with long gaps. The new v0.10.0 ends a roughly two-year quiet since the 2024 maintenance line, adding authentication on the attachments module, form-validation and default-company improvements, non-ASCII handling, and a JS back-button fix. Prior releases were predominantly security and PHP-compatibility maintenance.

Bullhorn vs OpenCATS: editorial side-by-side

B5.0

Bullhorn's feed is labor-market research and SMB advice, not release notes

◆ Current state

The current entries are market reporting and how-to content aimed at small staffing firms: monthly job-opening and hiring-order analyses, an argument that SMB data problems are smaller than firms assume, an ATS buyer's guide, and now two consecutive posts on whether and how a small agency should run an applicant tracking system. The recruiting data is Bullhorn's own — GRID survey figures and order and fill-rate trends — which gives it more substance than typical vendor content, but none of it describes the product changing.

◆ Where it's heading

Bullhorn is using its position in the staffing market as a data asset, publishing monthly labor-market reads that only a vendor with this order flow could produce. The advice content has narrowed hard onto small agencies — the last two posts run daily and both argue the same reader from spreadsheets into an ATS — which reads as a deliberate push down-market rather than a change in the product. Actual product news surfaces in this feed only occasionally, usually under a Tech Talk prefix, and does not appear in the current window.

◆ Prediction

Expect the monthly hiring reports to continue on cadence and the SMB acquisition series to keep running daily; product-level judgments about Bullhorn need a different source than this feed.

O2.5

OpenCATS breaks a two-year quiet with v0.10.0, tightening attachment auth and form UX

◆ Current state

OpenCATS, an open-source applicant-tracking system, ships rarely — its release history spans 2020 to 2026 with long gaps. The new v0.10.0 ends a roughly two-year quiet since the 2024 maintenance line, adding authentication on the attachments module, form-validation and default-company improvements, non-ASCII handling, and a JS back-button fix. Prior releases were predominantly security and PHP-compatibility maintenance.

◆ Where it's heading

The pattern is a community project moving in slow, security-conscious increments: authenticated attachments and earlier XSS/cookie hardening show steady attention to securing an aging codebase. v0.10.0 suggests renewed maintenance momentum rather than a feature pivot.

◆ Prediction

Expect continued infrequent releases focused on security hardening and PHP-version compatibility. A jump in cadence would be the signal to watch for renewed active development.
