highlight.io is a monitoring tool for the next generation of developers (like you!). Unlike the age-old, outdated tools out there, we aim to build a cohesive, modern and fully-featured monitoring solution, something we wished WE had. And it's all open source :)

At a high level, highlight.io's feature set is:

• Session Replay (read more here)
• Error Monitoring (read more here)
• Logging (read more here)

Read more about our features below.

We strive to make highlight.io as easy to install as a few lines of code in any environment.

The fastest and most reliable way to get started with highlight.io is signing up for free at app.highlight.io. After making an account, getting started is as easy as installing the client SDK snippet.

Deploy a hobby instance in one line on Linux with Docker (recommended 16 CPU cores, 32GB RAM, 256GB disk):

git clone --recurse-submodules https://github.com/highlight/highlight
# or `git submodule update --init --recursive` on git < 2.13

# if you want to run the backend in debug mode (attach GDB), run the following:
# export COMPOSE_FILE=compose.yml:compose.dev.yml:compose.debug.yml
# see the `docker/.env` file for other compose configurations.
cd docker && docker compose up -d --build

After a brief frontend load time, the app should be accessible at https://localhost:3000

Good for <10k sessions and <50k errors ingested monthly. See our docs for more info and limitations.

See our enterprise self-hosted docs to deploy a scalable, production-ready instance with support from our team.

All of our SDKs for highlight.io can be found in the sdk directory. We currently support:

• Server Libraries:
  • Node.js: repo link
  • Golang: repo link
• Client Libraries:
  • Javascript: repo link
  • Next.js: repo link

Our mission is to support developers like you in shipping with confidence. We do this by giving you the tools you need to uncover, resolve, and prevent issues in your web app.

We strive to build in public in every way we can. This means that what we built, what we're building, and what we plan to build is shared with the world.

People may think that we're building multiple products (session replay, error monitoring, etc..). But we see it as one. Before we build anything new, we prioritize making it operate seemlessly with everything else.

If you're building software, why should you care about grafana or loki or the elk stack? highlight.io is built for developers that want to develop. Leave the monitoring stuff to us 👍.
