Key Takeaways

  • Open-source Android SMS gateways on GitHub are other people’s control planes. This checklist is how you decide if a repo is production-shaped — not a claim that SMS Gateway is that repo.
  • Stars are not a DLR SLA. Score last commit, pairing docs, signed webhooks, and OEM battery notes.
  • MIT does not include operator airtime. You still BYO Android and carrier credit.
  • If nobody will patch the relay at 2am, you are not production-ready. You are demo-ready.
  • Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Maintained SaaS is the same radios with a hosted plane.

This is not our GitHub

Cornerstone: Android SMS gateway open source. Relay spoke: multi-device cloud relay explained. GitHub is a forge: GitHub. Maintained API: Developer Center.

A pinned README screenshot is not production. A pairing light that survives Tuesday is.

Tokens, webhooks, license

Rotate after contractors. Signed callbacks: webhook troubleshooting. License trade-offs have their own OSS spoke — do not ship GPL into a proprietary core by accident.

Score a repo before OTP

  1. Open the cornerstone first. Do not treat this checklist as the whole OSS buyer’s guide.
  2. Check commit and issue hygiene. Last meaningful commit, pairing bugs, DLR tickets. GitHub is a forge, not a warranty.
  3. Demand signed webhooks and idempotency. Unsigned inbound is a forge. Duplicate jobs burn airtime.
  4. Read battery and OEM docs. If they are missing, OTP will die overnight. You will write those docs yourself.
  5. Drill token rotation and a dead phone. Time to restore login codes. If it is hours, it is not ready.
  6. Compare staff time to maintained. Honest TCO includes VPS, TLS, and a human.

Setup physics still apply on DIY: device setup. OTP: OTP verification.

When maintained wins

Zero appetite for relay patches, need DLR history and device caps that finance understands. Contrast: Twilio vs Android. Docs for us: SMS API documentation.

True cost

Service pricing is based on device count and total SMS sent through the gateway. You need a working Android phone with a SIM and SMS credit from your mobile operator. Operator message costs are yours—we do not sell carrier SMS balance. OSS still needs VPS and airtime. Maintained from $19/month; Free 300 SMS lifetime to canary. Device and SMS volume pricing.

Next steps

Tick commits, HMAC, OEM docs, then a dead-phone drill. If that feels heavy, you already have the maintained answer.

FAQ

Frequently asked questions

Direct answers about android sms gateway open source checklist.

Is SMS Gateway the GitHub project this checklist is for?

No. Start from the open-source cornerstone, then use this spoke for production hygiene on DIY stacks. Live API fields for the maintained product are in Developer Center.

Does production-ready mean free unlimited SMS?

No. OSS never paid the carrier. Filters and fair-use still apply. Do not look for evasion tricks here.

What if the README has Docker Compose?

Necessary, not sufficient. Compose without TLS, HMAC, and a pairing runbook is a weekend project.

Where is the OSS overview?

Android SMS gateway open source. Relay architecture has its own spoke.
