Prompt versioning, with no visible activity in a year.
PromptHub handles prompt versioning and deployment for teams working with language models, covering a prompt library, version history, testing, comparison across models and a pipeline feature for chaining prompts. You supply your own model API keys. The application is live and functional. However the last blog post dates from October 2025, twelve months ago, there is no changelog or documentation site, the footer still carries the previous year's copyright, the operating company appears to be one or two people, and no funding has been disclosed. There is no MCP server: the company published writing about MCP security in 2025 but ships nothing itself.
Listed with its state described plainly rather than omitted, because the application works and someone may be using it. Prompt versioning is a real need for teams iterating on AI features, and bringing your own API keys keeps costs down. But the signals are not good: nothing published in twelve months, no changelog, no documentation site, last year's copyright still in the footer, a one or two person operation and no disclosed funding. That is a genuine continuity risk for anything you depend on. There is no MCP server despite the company writing about the protocol. Security certification is listed as in progress, there is no data processing agreement, no sub-processor list and no residency statement, and the pricing page advertises an encryption standard that does not exist, which tells you how much attention that page gets. PromptLayer does the same job and is visibly alive.
Best for: Few people in 2026, given the lack of visible development and the stronger alternatives.
Pricing: Free, then from $9/mo billed yearly (Freemium)
Rating: 2.5/5
