Tink vs HAProxy
HAProxy is a TCP/HTTP load balancer. That is not a mechanic. Tink installs in one command, watches the Linux server, explains what is wrong, and helps you fix it.
HAProxy keeps backends green. Tink answers “why is this VPS sick?”
Accidental sysadmins land on HAProxy because a VIP and health checks feel like monitoring. Then the volume fills, Postgres dies, and the stats page still showed UP — no backend check matched host fill. A filling /var is a Tink warning; it is not an haproxy.cfg job unless the balancer itself is the failure.
Tink is the other job: detect the issue on the machine, say why it happened in plain English, propose the command, and run it only after you approve. Keep HAProxy if you already terminate traffic on the box. Use Tink if you run Linux servers and want a mechanic.
| Feature | Tink | HAProxy |
|---|---|---|
| Setup time | 30 seconds (one curl | sh command) | Hours — haproxy.cfg frontends, backends, ACLs, stick tables, and still no host mechanic |
| What you get | Working monitoring, diagnosis, and approved fixes | L4/L7 balancing. Disk fill, SSH brute-force, and a quiet Postgres stay your problem until a backend check fails |
| Pricing | Free (Scout) / $9 / $29 per machine per month | Open-source (GPL). You still pay the VPS and the person who reads the stats socket when /var fills |
| Hidden costs | None — fully managed | Config reloads, SSL offload, maxconn tuning, and a second tool that pages you when memory climbs |
| Monitoring approach | Agent on the server — CPU, disk, services, logs, certs, ports | Backend health checks and optional Prometheus metrics. HAProxy does not watch host fill or auth.log |
| Configuration | None after install — heuristics and AI | haproxy.cfg frontends, backends, servers, and whether the stats page is bound to localhost |
| Plain-English diagnosis | Yes — AI explains root cause, impact, and fix | You read the stats page for DOWN servers, then SSH in to change the box |
| Fix execution | Proposes and executes approved commands with an audit trail | Balancer only — HAProxy cannot free disk, restart Postgres, or fail2ban an attacking IP |
| Alerting | Built-in across 8 channels | Not an HAProxy job — scrape stats or watch backends before anyone is paged about the host |
| Predictive alerts | Yes — disk fills in ~6 days, memory and CPU trends | Never — HAProxy answers TCP after traffic already arrived. It does not forecast a quiet volume filling up |
| SSH brute-force detection | Built-in — parses auth.log every scan | Never — HAProxy does not read auth.log, journald SSH, or host firewall state |
| Machine offline detection | Agent presence monitoring with multi-channel alerts | Silence if the process dies — unless an outside uptime check already watches the VIP |
| Public status page | Shareable URL with 90-day history | None — the stats page is operator-only, not a customer-facing fleet status page |
| Weekly fleet digest | Automated Monday digest + daily brief when issues are open | None — a backend DOWN line is not a plain-English fleet narrative |
| On-call tracking | Built-in /oncall command + incident acknowledgment | Not included — wire HAProxy checks into PagerDuty or another incident tool |
| Conversation interface | Telegram, WhatsApp, web dashboard, CLI | echo show stat | socat. No mechanic you text when /var filled and the VIP still looked fine |
| Learning curve | None — works after install | Steep — ACLs, stick-tables, ssl-offload, and which DOWN actually means the box is sick |
| Best for | Freelancers, small teams, accidental sysadmins (1-50 Linux servers) | Teams that already run HAProxy for L4/L7 and still need a separate mechanic for the Linux host |
When HAProxy is the right choice
Keep running HAProxy when you already want that exact job:
- L4/L7 load balancing — you need frontends, backends, and a VIP, not a mechanic.
- SSL offload in front of several app boxes — haproxy.cfg server lines matter more than fleet health scores.
- An existing uptime check on the public VIP — you already know the site is up, and someone owns the balancer config.
- Hosts that only page on backend DOWN — you already scrape HAProxy stats, not a sick-box SSH loop.
The real cost of “just run HAProxy”
HAProxy is a serious load balancer. A working ops loop for five Linux boxes is not:
- A green backend check still means you SSH in and change the box by hand
- Host fill, Postgres, and SSH brute-force never appear unless something else watched those signals
- A filling /var is a Tink disk warning on every scan — HAProxy will stay quiet until a backend check fails
- A single VPS with a dead HAProxy still needs a mechanic, not another frontend stanza
For a 5-server team, Tink Mechanic at $45/month is cheaper than HAProxy plus the engineer who tails the stats socket after the disk is already full, and every scan includes a diagnosis a quiet TCP handshake will not type.
No haproxy.cfg homework. No silent host. One command install.
