Key Takeaways

  • Security hardening checklist for open-source GitHub SMS gateway experiments: treat clones as untrusted until you review permissions, deps, and where keys land.
  • We are a commercial SaaS + official APK — not that GitHub listing.
  • Pin deps; scan for hardcoded secrets; never paste production keys into demo READMEs.
  • Self-host OSS still needs your Androids and operator airtime.
  • Our Free plan: 1 device / 300 SMS lifetime — devices + volume metering.

OSS SMS stacks still need gates

Security hardening checklist for open-source github: go/no-go before you wire production traffic through a cloned Android SMS gateway. OSS hub: open-source Android SMS gateway. Our product: Android SMS gateway. External: OWASP Top 10.

A README that says “paste your API key here” is documentation of a vulnerability, not onboarding.

Stars on GitHub are not a security review.

Supply chain

Prefer signed releases. Sibling habits: OSS secure keys.

Secrets and forks

Forks diverge — document who patches. SaaS alternative when you want a maintained control plane: setup.

Cost

OSS license ≠ free airtime. Our SaaS: devices + send volume; Free 1 device / 300 SMS lifetime. Starter, Professional, and Business list Unlimited SMS as platform send volume; that is not unmetered carrier SMS.

Go / no-go

  • Reviewed send + permission surfaces.
  • No committed secrets.
  • Pinned deps; known CVEs addressed.
  • Trusted APK build path.
  • Airtime + device ops owned.
