PostDeploy as a UptimeRobot alternative

PostDeploy puts Slack, Discord, webhook and Telegram alerts in every subscription, gives cron jobs their own allowance, and adds error tracking and analytics to the same projects. UptimeRobot keeps Slack and webhooks off its free plan and tracks no errors and no visitors. Get the alerts without a plan ladder. Switch to PostDeploy.

Pricing, tier by tier

Free is 50 monitors at a 5-minute floor, with Discord alerts. Slack is not on it.

Read the integration column, not the monitor count. Slack starts at the entry paid tier. Webhooks start two tiers above that. A team that wants Slack alerts and one webhook into an internal handler buys the higher tier long before it needs a 51st monitor.

PostDeploy is $29 a month, flat, with email, Slack, Discord, webhook and Telegram in every subscription: 10 projects, 100 uptime monitors, and 200 cron and heartbeat jobs on their own allowance.

The alert paywall and the missing pillars

A free monitor stops being free the moment a second person needs the alert in Slack. PostDeploy routes email, Slack, Discord, webhook and Telegram.

Most projects are an API, a marketing site, a staging host, four scheduled jobs and a question about last week's traffic. PostDeploy gives the jobs their own allowance, 200 in the package, and puts the errors and the traffic in the same project. UptimeRobot sells neither error tracking nor analytics.

Move off UptimeRobot

Each step happens once. Your agent recreates the checks through MCP, and the 14-day trial covers the move.

  1. 1 Read your monitors out through the UptimeRobot REST API: type, URL, interval, timeout, keyword rules and accepted status codes.
  2. 2 Let your agent recreate each check in PostDeploy through MCP.
  3. 3 Swap each heartbeat URL. A unique heartbeat.uptimerobot.com/<id> sits in each crontab, CI pipeline, Task Scheduler action or piece of application code. Replace it with the PostDeploy URL.
  4. 4 Point alerts at email, Slack, Discord, a webhook or Telegram.

Questions

How does PostDeploy compare with UptimeRobot's free plan?

UptimeRobot's free plan leaves out Slack and webhooks. PostDeploy has Slack, Discord, webhook and Telegram alerts, 100 uptime monitors, 200 cron and heartbeat jobs on a separate allowance, and error tracking and analytics, for $29 a month.

Can I monitor a cron job on PostDeploy?

Yes. Cron and heartbeat jobs have their own allowance of 200 in the package, separate from uptime monitors, so a scheduled job never consumes an uptime slot. A fail ping or a non-zero exit code opens an incident at once.

Does PostDeploy do port and DNS checks?

Yes. PostDeploy runs HTTP, keyword, TCP port and DNS checks, plus heartbeats and SSL and domain expiry warnings.
