Stack: Go; difficulty low-medium
License: AGPL (strong copyleft)
Source: GitHub · fetched 2026-11-02
Activity: last push about 5 months ago, slower cadence

Problem: improves one step of acquisition or conversion and makes growth work repeatable, focused on 邮件 and 邮件通讯. Audience: indie developers and growth operators. Stack & setup: Go, connect channel accounts and analytics, validate on a small budget before scaling, difficulty low-medium. Difference: it currently appears in only one source (GitHub), so cross-checking is advisable. Risk: AGPL is network copyleft: exposing it as a service usually requires publishing the corresponding source.
