+Self-hosted uptime monitor with a TUI you can access over SSH. No browser, no install on the client — just `ssh -p 23234 your-server`.

-  <img src="assets/demo.gif" alt="uptop demo" width="800">
-</div>
+Built on the foundation of [RDGames/go-upkeep](https://github.com/RDGames/go-upkeep).

-## What is this
+## What it does

-An uptime monitor you manage entirely from the terminal. It runs as a server, exposes an SSH endpoint, and drops you into a full TUI — monitors, alerts, logs, nodes, all there.
-
-Built on [RDGames/go-upkeep](https://github.com/RDGames/go-upkeep). Rewritten for clustering, config-as-code, and a proper dashboard.
-
-Canonical repo: [gitea.lerkolabs.com/lerkolabs/uptop](https://gitea.lerkolabs.com/lerkolabs/uptop) — [GitHub](https://github.com/lerkolabs/uptop) is a mirror; releases are published to both.
-
-## Features
-
- **6 check types** — HTTP, Push (heartbeat), Ping, Port, DNS, Groups
- **10 alert providers** — Discord, Slack, Email, Ntfy, Webhook, Telegram, PagerDuty, Pushover, Gotify, Opsgenie
- **Config as code** — define monitors in YAML, apply declaratively, version control your setup
- **HA clustering** — leader/follower with automatic failover
- **Prometheus metrics** — `/metrics` endpoint (`UPTOP_METRICS_PUBLIC=true` to expose without auth)
- **Public status page** — HTML + JSON, toggle with an env var
- **SQLite or Postgres** — SQLite for single-node, Postgres for production
- **Uptime Kuma import** — migrate from Kuma with one command
-
-> Group monitors roll up child status for display but don't fire their own alerts yet — attach alerts to the children.

 ## Quick start

 ```bash
-UPTOP_ADMIN_KEY="$(cat ~/.ssh/id_ed25519.pub)" go run ./cmd/uptop
+go run cmd/uptop/main.go
 ssh -p 23234 localhost
 ```

-Want some data to look at first:
+Seed some demo data to see it in action:

 ```bash
-UPTOP_ADMIN_KEY="$(cat ~/.ssh/id_ed25519.pub)" go run ./cmd/uptop -demo
+go run cmd/uptop/main.go -demo
 ```

 ## Install

-
-First run: set `UPTOP_ADMIN_KEY` to your SSH public key.
-
-The `sysctls` line enables unprivileged ICMP inside the container — without it, ping monitors get no response and silently report DOWN.

-See [`.env.example`](.env.example) for all options including TLS, probes, and advanced settings.
-
-### Running behind a reverse proxy
-
-By default uptop ignores the `X-Forwarded-For` header and rate-limits by the direct connection address — so a client can't spoof the header to bypass limits. If uptop sits behind a reverse proxy (nginx, Caddy, Cloudflare, an ALB), set `UPTOP_TRUSTED_PROXIES` to the proxy's address(es) so the real client IP is used instead:
-
-    # single nginx/Caddy on the same host
-    UPTOP_TRUSTED_PROXIES=127.0.0.1
-
-    # a proxy subnet, or Cloudflare ranges
-    UPTOP_TRUSTED_PROXIES=10.0.0.0/8,172.16.0.0/12
-
-Only requests whose immediate peer is in this list have their `X-Forwarded-For` honored (right-most non-trusted hop wins). Bare IPs are treated as single hosts; invalid entries are warned about and skipped. Leave it unset if uptop is exposed directly.
-
-### Encryption
-
-Set `UPTOP_ENCRYPTION_KEY` to encrypt alert credentials (SMTP passwords, webhook URLs, API tokens) at rest with AES-256-GCM. Generate a key:
-
-    openssl rand -hex 32
-
-Without this, credentials are stored as plaintext in the database. uptop warns on startup if unset. To encrypt credentials on an existing install, run `uptop migrate-secrets` with the key set.
-
-### Data retention
-
-uptop prunes its own history in the background — no external cleanup jobs needed:
-
-| Data | Kept |
-|---|---|
-| Check history | newest 1,000 checks per monitor |
-| State changes (UP/DOWN transitions) | newest 5,000 per monitor |
-| Logs | newest 200 entries |
-| Maintenance windows | 7 days after they end (`UPTOP_MAINT_RETENTION`) |
-
-Sparklines, uptime percentages, and SLA reports are computed from these windows, so very long-horizon stats aren't retained. Export to Prometheus via `/metrics` if you need unlimited history.
-
-## Clustering
-
-uptop supports three modes: **leader** (default single node), **follower** (HA failover — takes over if the leader goes down), and **probe** (stateless distributed checks from multiple regions).
-
-See [docs/clustering.md](docs/clustering.md) for setup guides, or the working examples in [`deploy/`](deploy/).

-# Clustering
-
-uptop supports three deployment modes for different reliability and coverage needs.
-
-## Single node (default)
-
-Out of the box, uptop runs as a standalone leader. One process, one database, runs all checks. No clustering config needed.
-
-## Leader + follower (HA failover)
-
-A follower is a standby replica that takes over if the leader goes down.
-
-**How it works:**
- The follower polls the leader's `/api/health` endpoint every 5 seconds
- After 3 consecutive failures (15 seconds), the follower promotes itself and starts running checks
- When the leader recovers, the follower detects it and goes back to standby
- Both nodes have their own database — they do not share state
-
-**Limitations:**
- During a network partition where both nodes are healthy, both will run checks and fire alerts independently. There is no leader fencing — the follower has no way to confirm the leader is actually down vs. unreachable from its perspective. This window lasts until the partition heals, at which point the follower detects the leader and steps down.
- Expect duplicate alerts and doubled check history entries during a split-brain event. Alerts are idempotent for most providers (a second "site is down" notification is noisy but not harmful).
- Failover takeover time is ~15 seconds (3 missed polls × 5 second interval). This is not configurable.
-
-**Required env vars:**
-
-| Node | Variable | Value |
-|------|----------|-------|
-| Both | `UPTOP_CLUSTER_SECRET` | Same shared secret |
-| Follower | `UPTOP_CLUSTER_MODE` | `follower` |
-| Follower | `UPTOP_PEER_URL` | Leader's HTTP URL (e.g. `http://leader:8080`) |
-
-See [`deploy/docker-compose.cluster.yml`](../deploy/docker-compose.cluster.yml) for a working example.
-
-## Leader + probes (distributed monitoring)
-
-Probes are lightweight, stateless nodes that run checks from different locations and report results back to the leader.
-
-**How it works:**
- A probe registers with the leader on startup
- Every 30 seconds, it fetches check assignments filtered by its region
- It runs the assigned checks (up to 10 concurrent) and posts results back
- The leader aggregates results from all probes and triggers alerts based on the aggregation strategy
- Probes have no database, no UI, and no configuration of their own
-
-**Required env vars:**
-
-| Node | Variable | Value |
-|------|----------|-------|
-| Both | `UPTOP_CLUSTER_SECRET` | Same shared secret |
-| Probe | `UPTOP_CLUSTER_MODE` | `probe` |
-| Probe | `UPTOP_PEER_URL` | Leader's HTTP URL |
-| Probe | `UPTOP_NODE_ID` | Unique identifier (e.g. `probe-us-east`) |
-
-Optional: `UPTOP_AGG_STRATEGY` (default `any-down`), `UPTOP_NODE_REGION` (omit to match all monitors), `UPTOP_NODE_NAME` (human-readable label in the TUI).
-
-See [`deploy/docker-compose.probe.yml`](../deploy/docker-compose.probe.yml) for a multi-region example.
-
-## Aggregation strategies
-
-When multiple probes check the same monitor, the leader combines their results:
-
-| Strategy | Behavior |
-|----------|----------|
-| `any-down` (default) | DOWN if **any** probe reports down |
-| `majority-down` | DOWN if **most** probes report down |
-| `all-down` | DOWN only if **all** probes report down |
-
-Set via `UPTOP_AGG_STRATEGY` on the leader.
-
-## Follower vs probe
-
-| | Follower | Probe |
-|---|---|---|
-| **Purpose** | Failover / redundancy | Distributed checks from multiple regions |
-| **Database** | Own database (independent) | None (stateless) |
-| **Runs checks** | Only when leader is down | Always, on assigned monitors |
-| **Scales to** | 1 follower per leader | Many probes per leader |
-
-## Security
-
- Set `UPTOP_CLUSTER_SECRET` on all nodes. Without it, cluster API endpoints reject all requests (fail closed); only `/api/health` stays open.
- Secrets are sent in HTTP headers (`X-Uptop-Secret`). Use TLS or a reverse proxy for production.
- uptop warns on startup if the cluster secret is missing or if cluster mode is active without TLS.

 Apply is idempotent. Run it twice with the same file, second run changes nothing.

-Apply is **not atomic** — items are written one at a time, so an error mid-apply (bad value, lost DB connection, ctrl-C) leaves the items already written in place. That's safe to recover from: apply diffs against the database by name, so fix the issue and run it again — it converges the rest. Just don't run two applies against the same database at once.
-
-## Backups and secrets
-
-`uptop export` writes alert credentials (SMTP passwords, API tokens, webhook URLs) into the YAML in clear text — that's what makes the file restorable. Treat it like a secrets file.
-
-The HTTP export endpoint redacts those same fields **by default**:
-
-```bash
-# secrets show as ***REDACTED*** — fine for sharing or review
-curl -H "X-Uptop-Secret: your-secret" \
-  "http://localhost:8080/api/backup/export"
-
-# full backup you can actually restore from
-curl -H "X-Uptop-Secret: your-secret" \
-  "http://localhost:8080/api/backup/export?redact_secrets=false"
-```
-
-Restoring a redacted export imports the literal string `***REDACTED***` as your credentials. For real backups, pass `redact_secrets=false` or run `uptop export` on the host.
+If something fails mid-apply, just fix the issue and run it again. It picks up where it left off.
