Real-time, at a glance.

Live stream of your logs in motion. Errors highlighted the moment they happen. Works with nginx, Apache, Kubernetes, or any JSON logs.

Live motion

A visual stream that makes spikes and anomalies obvious at a glance.

Errors surfaced

4xx/5xx are emphasized so incidents don't hide in success noise.

Multiple themes

Why settle for boring charts? Switch between sleek particle flows, arcade-inspired layouts, or classic streams. Monitoring that actually matches your vibe.

Wallboard-ready

Perfect for NOC screens and incident rooms.

Designed for speed

Redis Streams + TimescaleDB under the hood for smooth ingest and replay.

Replay past events

See what happened in the past and get a better understanding of what's happening now.

Why teams use Tailstream

Compare Tailstream’s live-first approach with staring at log tails or waiting on static dashboards.

Features

Tailstream focuses on the real-time pulse of your systems so you always know what's happening right now.

Tailstream

Built-in

Traditional logging

Manual effort

Real-time particle streams

Fluid particle visualizations that make traffic spikes and anomalies pop instantly.

Scrolling text logs or delayed charts hide trends until it’s too late.

Automatic error spotlight

4xx and 5xx responses are emphasized the moment they appear in the stream.

You have to manually scan for status codes or wire up separate alerts.

Multiple visualization themes

Swap between particle flows, arcade-inspired layouts, or classic streams that fit your workspace.

One-size-fits-all graphs that can’t adapt to the room they’re in.

Instant wallboard mode

Launch a NOC-friendly display built for incident rooms and big screens.

Requires hand-built dashboards that never quite fill the wall properly.

Works with your logs

Drop in nginx, Apache, Kubernetes, or any JSON log stream—Tailstream handles them all.

Adapters and ETL plumbing for every source before you can even see traffic.

Replay past events

Scrub back through earlier traffic to understand what led to right-now behavior.

Dig through stored logs and try to mentally reconstruct the timeline.

Setup in under a minute

Install the Tailstream agent with a single curl command and start streaming.

Provision infrastructure, configure agents, and piece together dashboards.

Frequently asked questions

Answers to common questions that help you decide if Tailstream is right for your team.

Why should I use Tailstream?
Tailstream turns raw logs into a live pulse of what your systems are doing right now. Getting started takes minutes. Drop in our agent or point your existing pipeline nd you immediately see real-time visualizations that surface spikes, anomalies, and signal patterns without sifting through dashboards.
Is there a free plan?
Yes. The Free plan includes 100K events/month and 24-hour retention — perfect to try Tailstream or use for small projects.
What counts as an event?
An event is a single log entry or message that Tailstream receives. Each request, error, or other notable activity you forward counts as one event.
How is Tailstream different from Datadog or Grafana?
Tailstream is a real-time, visual complement to your observability stack. Use Tailstream alongside providers like Datadog and Grafana: keep metrics, traces, and deep log search where they live today, and add Tailstream to instantly see live traffic, errors, and patterns at a glance. We don’t replace your log storage or dashboards - we make what’s happening right now obvious.
What data does Tailstream store?
Tailstream stores only the log fields you choose to send. Avoid including sensitive or personal data; most setups forward request method, path, status, timing, and host only.
How is Tailstream priced?
Plans are based on monthly event volume and data retention. The Free plan includes 250K events/month with 24-hour history; paid plans increase history and sharing. If you exceed your allowance we simply meter usage—upgrade anytime. See the Pricing section above for details.
What happens if I hit my plan limit?
We continue accepting events and simply meter usage. You can upgrade anytime for higher allowances and retention. We will automatically inform you when you are approaching your limit and when you have exceeded it.
How do I send logs to Tailstream?
The best way to get started is to use our open source agent, but if you prefer, you can use your existing pipeline (Vector or Fluent Bit) to POST JSON logs to our ingest endpoint using a token. No app code changes required.
Can I cancel anytime?
Yes. Subscriptions are month-to-month and can be cancelled at any time from settings. You retain access until the end of the billing period.
Will Tailstream slow down my application?
No. Logs are forwarded asynchronously by your logging agent, not on your request path. Tailstream does not run inside your app servers.

Built for teams who need to see what's happening right now.

Perfect for incidents, NOC screens, and live demos. Spin it up in minutes and keep it running in the background.
