Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Atlantis
- There is no company, no service level agreement and no paid support at any price, and the six maintainers are volunteers with day jobs, which some risk committees will not accept for a component holding production cloud credentials
- The security surface is inherently sharp, because it is an internet-reachable webhook endpoint that executes applies with privileged credentials, gated by pull request comment authorisation that is coarse next to a real policy engine
- It is stateful, holding a working directory and lock database on local disk, so high availability and horizontal scaling are awkward and you own upgrades, webhook plumbing, secret rotation and the host itself
- It lacks the features that distinguish the commercial alternatives, with no native drift detection, no cost estimation, no managed state interface and no policy engine beyond the Conftest integration
- Terragrunt and monorepo layouts are not first-class, requiring hand-written custom workflows and repository configuration that becomes a growing maintenance burden as the number of repositories increases
ChartMogul
- The free tier stops at $10K MRR, so it lapses precisely as a company starts to matter
- Starter is capped at 3 team members and a single billing system connection
- Two-way CRM sync and warehouse integration require the Pro tier
- Pricing scales with your ARR rather than with usage, so the bill rises as the business grows
- Enterprise starts at $19,900 a year and is required above $10M ARR
