Stop guessing which one. Put them side by side.

The grid says what these tools are. This says what builders did about it — one decision per person, changeable whenever you change your mind.

# Tool comparison — LogRocket vs Highlight.io vs Axiom

Source: Kbaise, a directory of tools that work with Lovable projects.
Pick one and tell me why before writing any integration code.

## LogRocket (logrocket)
- URL: https://logrocket.com
- Category: Monitoring & error tracking
- Cost: paid — No advertised free plan as of August 2026. Usage-based on captured sessions, starting around $176/mo for roughly 25K sessions. 14-day trial.
- What it is: Frontend monitoring that pairs pixel-accurate session replay with console logs, network requests, Redux or state changes and error traces on a single timeline. Billing is per captured session while analytics, log and error events stay unlimited. Effectively cloud-only for anyone below enterprise.
- Why builders pick it: When a bug only reproduces for one specific user, replaying their exact session with the network waterfall and console output attached beats any amount of log grepping.
- Trap: The old 1K-sessions-per-month free tier is gone and current pricing is sales-quoted, so get a number before instrumenting. Replaying logged-in users records PII unless you configure input masking and privacy rules.
- Wiring: npm i logrocket

## Highlight.io (highlight-io)
- URL: https://www.highlight.io
- Category: Monitoring & error tracking
- Cost: free — Self-hosting is free under Apache 2.0. The hosted cloud ended 28 February 2026 and existing users were migrated to LaunchDarkly Observability.
- What it is: An open-source full-stack monitoring app combining session replay, error monitoring, logging and OpenTelemetry tracing in one self-hostable Docker stack. LaunchDarkly acquired it and folded the features into LaunchDarkly Observability. The GitHub repo remains public and actively committed to, but the hosted app.highlight.io service has shut down.
- Why builders pick it: It is now purely a self-host play: if you want replay plus errors plus traces on your own hardware with no per-event bill, this is one of very few Apache-2.0 options.
- Trap: Do not plan around the cloud product. It ended on 28 February 2026 and SDK snippets had to be repointed at LaunchDarkly before 1 March 2026. Self-hosting means operating ClickHouse, Kafka and Postgres yourself.
- Wiring: git clone https://github.com/highlight/highlight && docker compose up

## Axiom (axiom)
- URL: https://axiom.co
- Category: Monitoring & error tracking
- Cost: mixed — Free Personal: 500GB ingest/mo, 25GB storage, 30-day retention, 10 GB-hours query. Axiom Cloud $25/mo platform fee including 1TB ingest, 100GB storage and 100 GB-hours.
- What it is: A serverless log and event store built on object storage and queried with the APL language, with dashboards, monitors and native OpenTelemetry ingest. The permanently free Personal plan allows 500GB of ingest per month, which is enormous for a solo project. Cloud-only, no self-hosted build.
- Why builders pick it: 500GB a month free is more log volume than a side project will ever generate, and the Vercel and Cloudflare integrations mean you can ship logs without writing a shipper.
- Trap: Free retention is fixed at 30 days and query compute is capped at 10 GB-hours per month, so busy dashboards hit that ceiling long before ingest becomes the constraint. No self-hosting option exists.

## Quick read

- Free with no card: Highlight.io.

## Rules
1. Prefer the free tier when no budget was stated, and say what the ceiling is.
2. Read the full dossier before integrating.
3. Fetch /api/public/models before writing any AI model ID.
