Factorial HR vs Miter
A side-by-side editorial comparison of Factorial HR and Miter — release velocity, themes, recent moves, and the top alternatives to consider.
Factorial HR vs Miter: at a glance
What is Factorial HR?
Factorial's API ships quarterly versions, and added an MCP server and SDKs this summer.
Factorial's developer changelog follows dated API versions: 2026-04-01, 2026-07-01 and 2026-10-01 have shipped, and 2027-01-01 release notes are already posted. In July it added an MCP server and official TypeScript and Python SDKs with a skill for AI coding agents. The version entries carry no detail in this feed.
What is Miter?
Miter added accounts payable and opened a free API — it's no longer just construction payroll.
Miter ships one large digest every one to two months rather than continuous entries, and each is organized by module: HR, Payroll, Field Ops, Spend, Platform, Ecosystem. The summer update is the broadest yet, adding an Accounts Payable module, API 2.0 as a free self-serve install, Safety Passport credential verification, entity-scoped granular permissions, and a run of payroll and compliance work including California break rules and OSHA report generation.

◆ Current state
Factorial's developer changelog follows dated API versions: 2026-04-01, 2026-07-01 and 2026-10-01 have shipped, and 2027-01-01 release notes are already posted. In July it added an MCP server and official TypeScript and Python SDKs with a skill for AI coding agents. The version entries carry no detail in this feed.
◆ Where it's heading
The API is on a predictable quarterly release train with notes published a quarter ahead, which suits integrators planning upgrades. The July MCP server and agent skill show Factorial treating AI assistants and coding agents as API consumers alongside classic integrations.
◆ Prediction
The 2027-01-01 API version is the next likely release, around the start of January, given the posted notes and quarterly pattern.
Miter
2.5HR
Miter added accounts payable and opened a free API — it's no longer just construction payroll.
◆ Current state
Miter ships one large digest every one to two months rather than continuous entries, and each is organized by module: HR, Payroll, Field Ops, Spend, Platform, Ecosystem. The summer update is the broadest yet, adding an Accounts Payable module, API 2.0 as a free self-serve install, Safety Passport credential verification, entity-scoped granular permissions, and a run of payroll and compliance work including California break rules and OSHA report generation.
◆ Where it's heading
The module list keeps growing outward from payroll into everything a contractor's back office touches, and the last two releases added the two things a platform needs that a payroll product does not: a spend module of its own and an open, unmetered API. Vote counts published against each feature show the roadmap is being run off customer demand, and the compliance work is concentrated where construction is most exposed — break rules, OSHA, prevailing rate calculations.
◆ Prediction
Expect the Spend module to keep filling out around Accounts Payable, and third-party integrations built on API 2.0 to start appearing in the Ecosystem section of the next digest.
