If you have a large Postgres database and need to migrate it to a new host - whether that's Fly.io to AWS RDS, self-hosted to managed, or any provider-to-provider move - a simple dump-and-restore will take your app offline for hours. For PagerTree, that amount of downtime was not acceptable. Instead, I used Postgres's built-in logical replication to stream data continuously from the old database to the new one while the app stayed live. This approach allowed me to keep downtime to about 10 minutes - just long enough to stop the app, verify replication is caught up, reset sequences, and point the app at the new database.

AT&T, T-Mobile, and Verizon have all shut down their free email-to-text gateways. These gateways powered what most teams think of as "email-to-SMS" - sending an email to a phone number to trigger a text message. If your scripts, monitoring systems, or alerting tools are still pointing at @txt.att.net, @tmomail.net, or @vtext.com - your alerts are silently failing.

PagerTree is the drop-in replacement. Just replace the domain. Everything else stays the same. PagerTree uses verified messaging infrastructure (A2P 10DLC), ensuring messages are delivered reliably instead of silently dropped like legacy gateways.

Today, we are excited to release the all-new PagerTree Command Line Interface (CLI), a slick tool for managing alerts and integrations from your terminal.

The PagerTree CLI is all about speed and "scriptability". Automate alert handling in scripts, manage integrations in seconds, and stay in your terminal flow. Plus, it’s open-source on GitHub so you can tweak it to your heart’s content. Check out the docs to dive in!

The incident management landscape is shifting, and for OpsGenie users, change is on the horizon. Atlassian recently announced that OpsGenie, a staple in on-call and alerting solutions, will no longer be available for new purchases after June 4, 2025, with full support ending on April 5, 2027. This news has left many teams scrambling to find a reliable alternative that ensures seamless incident response without breaking the bank. If you’re an OpsGenie user, now is the time to evaluate your options—and PagerTree stands out as the smartest choice to future-proof your operations.
