Things I built that you can use.
Free, offline-first operations tools and a monitoring product. Everything read-only or safe by design, most needing no account and no install. Built from real incidents, for DBAs and SREs.
FLAGSHIP · FREESQL Field Kit
An offline triage toolkit for SQL Server Always On / HADR and PostgreSQL. Failover audits, an AI analyst that turns a paste into a runbook, and a full SSMS-style training simulator. All in the browser, connecting to nothing. The tool a locked-down team can actually adopt.
AI Analyst
Paste an error log, wait stats, or DMV output. Get severity, likely cause, what to check next, and the fix. Nothing stored.
Free · runs on your paste TRAININGFailover Simulator
Real HADR incidents replayed in an SSMS + PowerShell sandbox. Novice to expert, no lab servers needed.
Free · runs in-browser MONITORING · SAASStatusOwl 🦉
Uptime and status-page monitoring I built and run. Know before your users do. Checks, alerting, and a clean public status page.
Product · statusowl.ioThe Field Kit family
The same offline, read-only philosophy across the stacks you actually run. SQL is live; the rest are rolling out.
SQL Server 🗄️
HADR triage, failover audits, AI analyst, training sim. The flagship.
Free · in browser LIVEPostgreSQL / RDS 🐘
Replication, WAL, vacuum, and RDS/Aurora triage. The Postgres companion.
Free · in browserLinux Field Kit 🐧
Paste top, dmesg, systemctl, disk and memory output. Triaged with the right next command. A read-only "what's wrong with this box" companion.
Building nowTerraform Field Kit 🏗️
Read a plan, spot the destructive changes before apply, decode state drift, and catch the "this will replace prod" line that scrolls by.
Building nowDocker Field Kit 🐳
Container won't start, image won't build, network won't route. Paste the logs and inspect output, get the likely cause and the check.
Building nowKubernetes Field Kit ☸️
CrashLoopBackOff, pending pods, OOMKills, and the events nobody reads. Paste kubectl describe and get triaged.
Building nowPowerShell Toolkit ⚡
Read-only diagnostic scripts and one-liners for Windows and SQL. Pull the status of a service, a session, an AG, without memorizing the incantation.
Building nowUtilities
Log Analyzer 🔎
Paste a wall of log output, SQL error log, syslog, application log. And get it grouped, ranked by severity, and pointed at the lines that matter. Pattern-first, offline, no upload.
Building nowQuery Writer 📝
Describe what you need to check, "is this AG healthy," "what's blocking session 52," "which logins are orphaned". And get the read-only script to run. A safe recall layer for the queries you always half-remember.
Building nowIncident Command Kit 🎯
A browser-based coordinator that walks a solo on-caller through roles, timeline capture, comms templates, and a severity decision tree. Then exports a clean postmortem skeleton. Nothing stored. Pairs with the AI Analyst.
Building nowSLO / Error-Budget Calculator 📉
Enter request and error counts, get burn rate, budget remaining, and alerting-threshold suggestions. Fully client-side. The kind of thing every SRE team needs and can never get past procurement.
Building nowRunbook Builder 📗
Turn messy notes into a structured, testable runbook. Preconditions, steps, rollback, verification. Extends the "turn a paste into a runbook" idea end to end.
