How to Upgrade

​
From Free to Starter

Authenticate with GitHub: 
sher login
This opens your browser to authorize Sher with GitHub. Once complete, you’ll have Starter tier access.

​
From Starter to Pro

Upgrade to Pro via Polar: 
sher upgrade
This opens a Polar checkout session in your browser. Complete the payment to activate Pro features.
You can manage your Pro subscription (update payment method, cancel, etc.) from your Polar dashboard.

​
Rate Limit Behavior

Sher checks rate limits before building to save you time: 
$ sher link

Rate limit reached (1/day). Run `sher login` for up to 25/day.
This preflight check happens in src/index.ts:110-127: 
// Pre-flight rate limit check (before building)
try {
  const preflight = await checkPreflight();
  if (!preflight.allowed) {
    const upgradeHint =
      preflight.tier === "anon"
        ? `Run \`sher login\` for up to 25/day.`
        : preflight.tier === "auth"
          ? `Run \`sher upgrade\` for up to 200/day.`
          : "";
    console.error(
      `Rate limit reached (${preflight.limit}/day). ${upgradeHint}`
    );
    process.exit(1);
  }
} catch {
  // Preflight failed (offline, etc.) — continue and let upload handle it
}

​
Upgrade Suggestions

When you hit a rate limit, Sher suggests the next tier:
  • Free tier: “Run sher login for up to 25/day.”
  • Starter tier: “Run sher upgrade for up to 200/day.”
  • Pro tier: (no upgrade available — wait for reset)
