Shipping to Vercel faster than you can watch it? Logsitter keeps an eye on every project.
When you are vibe-coding a few apps and deploying all day, things break in the gaps. Logsitter reads your Vercel logs and pings Slack the moment it matters: a new error, a regression from your latest deploy, or a scanner that just found something. No SDK. No surprise bills. Your logs never leave Vercel.
Works with any Vercel Pro project · Free on Slack · No SDK, no log storage

From log to Slack in two minutes
No agent to install. No instrumentation. Logsitter reads the logs Vercel already produces.
Connect your Vercel project
Add Logsitter as a log drain by pasting one URL into your Vercel dashboard. Log Drains require a Vercel Pro plan. We start receiving logs instantly, no SDK or code changes.
Point us at Slack
Connect Slack in a couple of clicks and pick a channel. That is the whole integration. No Slack paid plan, no per-seat fees.
Get pinged when it matters
We classify errors, group duplicates, flag regressions from your latest deploy, and surface scanner probes that actually found something. One crash-loop becomes one alert, not five thousand.
Lightweight, but not on the things that matter
Errors, regressions and security alerts off your existing Vercel logs. Nothing you will never touch.
New since your last deploy
Deploying ten times a day? When an error first shows up right after a deploy, we tell you it is new since that deploy. No release config to wire up, it just works because we already see the deployment in your logs.
Catches attacks that landed
Scanners hammer every site all day. We stay quiet on the dead 404s and only ping you when a probe actually found something, like a served .env or an injection that reached your code.
Spikes, not timers
We re-alert an ongoing issue when it genuinely spikes, at 10x, 100x and beyond, instead of nagging you on a clock.
No surprise bills, ever
Flat and hard-capped. A runaway error loop can never run up a shock invoice. The opposite of per-event pricing.
No SDK, no log storage
Paste one log-drain URL and you are done. Nothing to install, no source maps to break, and we keep only fingerprints. Your logs never leave Vercel.
Quiet by default
Smart dedup, production-only filtering, ignore rules and throttling. Your channel stays signal, not spam.
Built for shipping fast on Vercel, not for Disney-scale
If you live on Vercel and Slack, you do not need a heavyweight tool that hoards your logs, makes you wire up an SDK, and bills you per event.
| Logsitter | Heavyweight tools | |
|---|---|---|
| Setup | One log-drain URL | An SDK in every app |
| Source maps | None to manage | Configure and hope they upload |
| Regressions | Auto: new since deploy X | Set up releases yourself |
| Scanner probes | Flagged when they land | Not its job |
| Your logs | Never leave Vercel | Stored on their servers |
| Bills | Flat, with a hard cap | Per-event, spikes cost you |
Priced like a tool, not a tax
Logsitter needs a Vercel Pro plan, since Log Drains are not on Hobby. Slack alerts are then free up to a generous monthly volume. You only pay for email or very high throughput, and those plans are coming soon.
