Tink vs OpenWrt
OpenWrt is Linux firmware for routers. It sits on the edge. It is not a mechanic. Tink installs in one command, watches the Linux host, explains what is wrong, and helps you fix it.
OpenWrt routes packets. Tink answers “why is this VPS sick?”
Accidental sysadmins land on OpenWrt because a cheap travel router or a used AP becomes “the firewall.” Then disk is at 91% on web-1, nginx dies, and last night's fw4 allow list does not say what to run. A filling /var is a Tink warning; it is not a LuCI graph.
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 using OpenWrt if you already want router firmware. Use Tink if you run Linux servers and want a mechanic. They can sit in the same shop.
| Feature | Tink | OpenWrt |
|---|---|---|
| Setup time | 30 seconds (one curl | sh command) | Flash a supported router, set WAN/LAN, opkg packages, LuCI, hope the edge stays the edge — then you still SSH into every Linux host when it is sick |
| What you get | Working monitoring, diagnosis, and approved fixes | Embedded Linux router OS — firewall, Wi-Fi, VLANs, SQM. Not a fleet mechanic for the servers behind it |
| Pricing | Free (Scout) / $9 / $29 per machine per month | Open source. You still pay the person who SSHs into nginx after the outage |
| Hidden costs | None — fully managed | A second box for the edge, image upgrades, package drift, and whether anyone watched /var on the app servers |
| Monitoring approach | Agent on the server — CPU, disk, services, logs, certs, ports | Edge traffic and the router itself. It does not watch fill time or propose a restart on the VPS behind the WAN |
| Configuration | None after install — heuristics and AI | uci, LuCI, fw4, wireless, VLANs, and whether last year's dump still matches the live config |
| Plain-English diagnosis | Yes — AI explains root cause, impact, and fix | No — you read kernel/logread and then SSH into the Linux host anyway |
| Fix execution | Proposes and executes approved commands with an audit trail | Changes firewall/Wi-Fi/routing only — OpenWrt cannot restart nginx, free disk, or rotate a cert on the app server |
| Alerting | Built-in across 8 channels | Optional packages and email. A silent WAN drop is not a Telegram diagnosis of the Linux box |
| Predictive alerts | Yes — disk fills in ~6 days, memory and CPU trends | Live edge graphs only — OpenWrt does not forecast fill time on the hosts behind it |
| Firewall / port exposure | Built-in — warns when the host firewall is inactive or dangerous DB ports listen | Yes for WAN/LAN — that is the job. It still will not say Redis is bound to 0.0.0.0 on web-1 |
| Machine offline detection | Agent presence monitoring with multi-channel alerts | If a Linux host is down behind the LAN, OpenWrt still shows the WAN as up |
| Public status page | Shareable URL with 90-day history | Not included — OpenWrt has no customer-facing status page for your app fleet |
| Weekly fleet digest | Automated Monday digest + daily brief when issues are open | Not included — a logread dump is not a plain-English fleet narrative |
| On-call tracking | Built-in /oncall command + incident acknowledgment | Not included — wire something else into PagerDuty |
| Conversation interface | Telegram, WhatsApp, web dashboard, CLI | LuCI + SSH. No mechanic you text when /var filled on the VPS |
| Learning curve | None — works after install | Low to flash and get DHCP; higher to keep fw4, VLANs, and sysupgrade honest |
| Best for | Freelancers, small teams, accidental sysadmins (1-50 Linux servers) | Operators who already want router firmware and will still SSH into every Linux host when it is sick |
When OpenWrt is the right choice
Keep using OpenWrt when you already want that exact job:
- Router firmware — WAN/LAN, Wi-Fi, VLANs, and SQM on a supported AP, not a fleet digest.
- Network appliance — OpenWrt is the perimeter; it is not a mechanic for the Linux hosts behind it.
- Custom edge hardware — travel routers, mesh nodes, and community builds that a $9 agent will not replace.
- No conversation layer wanted — some operators prefer LuCI and will never use a mechanic.
The real cost of “just put OpenWrt in front”
The edge box is cheap to flash. A working ops loop for five Linux boxes is not:
- A complete fw4 allow list still means you SSH into each host and change the box by hand when it gets sick
- Host fill, nginx, certs, and a quiet agent never appear unless you built extra checks on the Linux side
- A filling /var is a Tink disk warning on every scan — OpenWrt stays an edge graph until you are looking
- A single VPS with nobody logged in still needs a mechanic, not another LAN interface
For a 5-server team, Tink Mechanic at $45/month is cheaper than the engineer who opens logread after the outage, and every scan includes a diagnosis a quiet router will not type.
No SSH homework. No silent host. One command install.
