Tink vs Terraform
Terraform is HashiCorp infrastructure as code. It also records plans and applies. That is not a mechanic. Tink installs in one command, watches the Linux server, explains what is wrong, and helps you fix it.
Terraform applies the fleet. Tink answers “why is this VPS sick?”
Accidental sysadmins land on Terraform because every HashiCorp diagram starts with a plan. Then the volume fills, nginx dies, and the last apply still shows green — no resource matched host fill. A filling /var is a Tink warning; it is not a Terraform resource unless you coded the disk itself.
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 applying Terraform if you already operate infrastructure as code. Use Tink if you run Linux servers and want a mechanic.
| Feature | Tink | Terraform |
|---|---|---|
| Setup time | 30 seconds (one curl | sh command) | Hours — providers, state backend, workspaces, and a Terraform Cloud org before a run even exists |
| What you get | Working monitoring, diagnosis, and approved fixes | A green apply. Host disk fill, nginx, Postgres, and certs stay your problem until a later plan notices drift |
| Pricing | Free (Scout) / $9 / $29 per machine per month | Terraform OSS is free. HCP Terraform is paid. You still pay the engineer who owns state, plans, and the box after apply |
| Hidden costs | None — fully managed | A locked state file, a failed apply at 2am, and a second tool to tell you the VPS is sick after the run succeeded |
| Monitoring approach | Agent on the server — CPU, disk, services, logs, certs, ports | terraform apply exit codes, run status, and resource drift. Terraform does not watch a quiet cert unless you coded that resource |
| Configuration | None after install — heuristics and AI | backend, providers, workspaces, HCP org, and which run notification actually pages you |
| Plain-English diagnosis | Yes — AI explains root cause, impact, and fix | You read terraform plan output, then SSH in to change the box Terraform already applied |
| Fix execution | Proposes and executes approved commands with an audit trail | Apply only — Terraform cannot free disk, restart nginx, or rotate a cert that is already in state |
| Alerting | Built-in across 8 channels | Not a Terraform job — HCP run notifications and a separate monitoring tool have to fire |
| Predictive alerts | Yes — disk fills in ~6 days, memory and CPU trends | Not a Terraform job — a successful apply does not forecast a quiet volume filling up |
| SSH brute-force detection | Built-in — parses auth.log every scan | Never — Terraform does not read auth.log, journald, or host firewall state |
| Machine offline detection | Agent presence monitoring with multi-channel alerts | Silence if the box dies after apply — unless you built a separate uptime check |
| Public status page | Shareable URL with 90-day history | None — Terraform has no customer-facing status page |
| Weekly fleet digest | Automated Monday digest + daily brief when issues are open | None — an apply log is not a plain-English fleet narrative |
| On-call tracking | Built-in /oncall command + incident acknowledgment | Not included — wire run notifications into PagerDuty or another incident tool |
| Conversation interface | Telegram, WhatsApp, web dashboard, CLI | terraform plan and the HCP run UI. No mechanic you text when /var filled and the last apply still showed green |
| Learning curve | None — works after install | Steep — HCL, state, backends, workspaces, and which apply failure is the box vs the config |
| Best for | Freelancers, small teams, accidental sysadmins (1-50 Linux servers) | Teams that already run Terraform and need plan/apply SLOs, not a sick-VPS mechanic |
When Terraform is the right choice
Keep applying Terraform when you already want that exact job:
- Infrastructure as code — you need plans, state, and applies, not a mechanic.
- An existing Terraform estate — providers, backends, and workspaces matter more than host nginx, certs, and SSH on a quiet VPS.
- An existing HCP Terraform org — runs already exist, notifications already fire, and someone owns the state.
- Hosts that only page on apply — you already run exporters and PromQL, not a sick-box SSH loop.
The real cost of “just watch Terraform runs”
Terraform is in every HashiCorp provisioning diagram. A working ops loop for five Linux boxes is not:
- A green terraform apply still means you SSH in and change the box by hand when it gets sick later
- Host fill, nginx, certs, and SSH brute-force never appear unless a separate tool scraped those signals and a rule fired
- A filling /var is a Tink disk warning on every scan — Terraform will stay quiet until the next plan notices drift
- A single VPS with a dead agent still needs a mechanic, not another apply log
For a 5-server team, Tink Mechanic at $45/month is cheaper than Terraform Cloud plus the engineer who keeps run notifications alive, and every scan includes a diagnosis a quiet apply log will not type.
No apply homework. No silent host. One command install.
