Security Scanning / Mobile App Sec
The most concrete split between Alter and Checkov is the pricing model: Alter runs on custom pricing only (no public tier), while Checkov uses free and open-source. That shapes how predictable your monthly spend is and how much of the cost sits in infrastructure versus per-seat or per-event fees. Beyond the headline, Alter carries low lock-in (proprietary agent identity platform with custom protocols) and custom pricing only (no public tier); Checkov carries low lock-in (oss iac scanner by bridgecrew) and free and open-source. Alter is a fit when you are mobile. Checkov is a fit when you are mobile. The honest trade-off: Alter is explicitly not for hobby projects; Checkov is explicitly not for hobby projects. On the product side, Alter is described as Security Scanning / Mobile App Sec tool for developers. Specializes in Agent Identity, and Checkov is described as CI/CD for Applications tool for developers. Specializes in IaC Scanner.

Alter is for mobile; Checkov is for mobile; decide on pricing model.

Choose Alter if its custom pricing model fits your budget shape better than Checkov's free model, and you are mobile.
Not for: Hobby projects
Choose Checkov if you need a free tier to start before committing budget, and your use case matches mobile.

Headline yes, Checkov is free and open-source while Alter uses custom pricing only (no public tier). But the total cost depends on self-hosting and maintenance effort for Checkov versus managed convenience from Alter. Factor in both.
Migration from Alter to Checkov is plausible because Alter has low lock-in (proprietary agent identity platform with custom protocols). You would still have to map config, permissions and integrations to Checkov's model. Plan for dual-run and rollback.
On our scoring Checkov rates 5/5 for developer experience versus 3/5 for Alter. That suggests Checkov feels more polished for everyday developer tasks. We still recommend a short hands-on trial on your stack before standardising.
Checkov targets the same best-fit audience as Alter (mobile). Note that Checkov is explicitly not for hobby projects, so it only replaces Alter if you are outside that exclusion. Pricing models differ (custom vs free), which may shift total cost.
