SignalTo vs fabston TradingView Webhook Bot: Honest Comparison
Open-source fabston bot vs managed SignalTo forwarding: hosting, retries, logs, cost, and who should use which for TradingView alert delivery.
Last verified: July 2026
The fabston/TradingView-Webhook-Bot repo has thousands of GitHub stars for a reason: it's free, open source, and it forwards TradingView alerts to Telegram and Discord. I ran a version on a $5 VPS for months early in my signal-forwarding experiments.
SignalTo is the opposite bet — managed hosting, per-strategy endpoints, and delivery logs you don't SSH to read. Here's an honest comparison if you're choosing between them.
What each one does
| fabston Webhook Bot | SignalTo | |
|---|---|---|
| Core job | Receive TradingView POST → forward to chat apps | Same |
| Hosting | You (VPS, Docker, or home server) | SignalTo cloud |
| Setup time | ~30–60 min if you know Linux | ~5 min, no server |
| Monthly cost | VPS ~$5–12 + your time | Subscription (free trial available) |
| Auto-retry on failure | You implement it | Built in |
| Delivery audit trail | Log files you maintain | Dashboard with HTTP codes |
| Multi-channel routing | JSON keys per alert | Per-strategy endpoints + routes |
| 3-second TradingView timeout | You must return 200 fast | Designed for it |
| Auto-trading | No (notification only) | No (notification only) |
Neither tool places broker orders. Both sit in the notification layer.
Where fabston wins
Price at scale. If you already pay for a VPS running other services, marginal cost is near zero. The MIT license lets you fork and customize without asking anyone.
Full control. Want to add a custom filter, route alerts based on a secret key in the JSON, or pipe into a database you own? It's your Python code.
Community recipes. Years of GitHub issues and blog posts show exact config.py shapes. Copy-paste culture is real.
Where fabston hurts
Uptime is on you. VPS reboot, expired SSL cert, disk full, Python process crashed — alerts stop until you notice. I've missed entries because pm2 didn't resurrect after a kernel update.
The 3-second rule. Flask handling the request synchronously while also posting to Telegram? Fine most days. One slow Telegram API call during a volatile open and TradingView marks the delivery failed. No retry from TradingView's side.
Security maintenance. TradingView webhooks have no signature verification. Your secret-in-JSON pattern is only as good as your firewall and HTTPS setup. You rotate keys manually.
No deduplication. Network hiccups can double-fire alerts. You build dedup or live with spam.
Where SignalTo wins
Operations you don't want. SSL, scaling, monitoring, and async receive-then-forward logic are the product. You paste a URL into TradingView and configure channels in a dashboard.
Retries and logs. When Discord returns 502, SignalTo retries with backoff. You see "received → queued → delivered / failed" without tail -f on a server.
Per-strategy isolation. Different webhook URLs for BTC vs ETH strategies, different Telegram chats, one place to audit.
Faster time-to-first-alert. No Docker, no firewall rules, no certbot cron.
Where SignalTo hurts
Recurring cost. A VPS bot is "free" after setup if you ignore your time. SignalTo charges for the managed layer.
Less custom logic. If you need exotic routing — "only forward if RSI < 30 AND volume > X parsed from custom fields" — you'll outgrow a managed forwarder and want your own code.
Vendor dependency. fabston is code you hold. SignalTo is a service you trust to stay up.
Who should use which?
Pick fabston (or your own fork) if:
- You enjoy running Linux and already have infra
- You need custom parsing or database writes on every alert
- Budget is tight and your time is cheap
Pick SignalTo if:
- You trade, not administer servers
- You need proof alerts delivered (logs for a signal group or prop team)
- You've already lost signals to timeout or silent Discord failures
Pick neither for auto-trading — look at broker-specific execution layers. Both tools are notification pipes.
Migration path
A common pattern: start on fabston, lose an alert during a VPS outage, move to managed forwarding for production strategies, keep a fabston fork in a lab for experiments.
SignalTo accepts the same TradingView JSON payloads. Swap the webhook URL in your alert — no Pine Script changes required.

My take: fabston is a great learning project and a legitimate production choice if you operationalize it like real infra. SignalTo is what I reach for when the cost of a missed alert exceeds the subscription fee — which for most active traders is the first bad fill, not the monthly bill.
Try SignalTo free if you want managed forwarding without retiring your VPS scripts overnight.
