What is Kombo?

Kombo expands its unified HR API into Payroll data models, opening a new data category for integration builders.

Kombo is a unified HR integration API shipping on a weekly changelog cadence, covering ATS, HRIS, LMS, and — as of August 30 — Payroll data models. Recent releases have a dual rhythm: graduating integrations from beta to General Availability in bulk while simultaneously adding new ones (Atlas, Skello, Zellis, Talent360). Integration depth is also growing, with Workday performance overhauls, Lever high-performance sync modes, and Greenhouse scorecard sync all landing in August.

What is TimeTagger?

A time tracker that ships twice a year and spends it on self-hosters.

TimeTagger is a self-hosted time tracker maintained by a small core with a steady stream of outside contributions. Releases land two or three times a year and bundle whatever community PRs arrived rather than a planned roadmap. Recent work concentrates on the deployment and integration surface — an API for external tooling, a hardened default binding, offline usage — rather than the tracking UI itself.

Kombo vs TimeTagger: editorial side-by-side

K7.5

Kombo expands its unified HR API into Payroll data models, opening a new data category for integration builders.

◆ Current state

Kombo is a unified HR integration API shipping on a weekly changelog cadence, covering ATS, HRIS, LMS, and — as of August 30 — Payroll data models. Recent releases have a dual rhythm: graduating integrations from beta to General Availability in bulk while simultaneously adding new ones (Atlas, Skello, Zellis, Talent360). Integration depth is also growing, with Workday performance overhauls, Lever high-performance sync modes, and Greenhouse scorecard sync all landing in August.

◆ Where it's heading

The product is expanding its data model surface area (Payroll is the newest) while tightening the reliability of existing connections. AI-assisted formula generation for custom field mapping reduces the configuration burden for complex data transformations. The trajectory is toward a comprehensive HR data fabric that covers the full employment data stack rather than just ATS/HRIS connectors.

◆ Prediction

Payroll data model launch typically precedes specific payroll integrations — expect Gusto, ADP, or Paychex connectors in the next 30-60 days. Advanced Mappings AI assistance will likely expand to more formula types and field contexts as adoption grows.

T0.0

A time tracker that ships twice a year and spends it on self-hosters.

◆ Current state

TimeTagger is a self-hosted time tracker maintained by a small core with a steady stream of outside contributions. Releases land two or three times a year and bundle whatever community PRs arrived rather than a planned roadmap. Recent work concentrates on the deployment and integration surface — an API for external tooling, a hardened default binding, offline usage — rather than the tracking UI itself.

◆ Where it's heading

The center of gravity has moved from the timeline UI toward how an instance is run and scripted against. v25.12.1 added a version endpoint and server-side record filters, which are the pieces an operator needs to automate against a deployment; v24.12.2 moved the default bind to loopback after an auth gap. The app-facing changes in the same window are smaller and mostly contributed.

◆ Prediction

The next release will most likely extend the records API further, since that is where the last cycle of contributions concentrated. The two-releases-a-year cadence gives no basis for predicting when.
