telescope

Laravel Telescope is a first-party debugging and monitoring tool for Laravel applications that captures requests, exceptions, database queries, jobs, mail, cache operations, and scheduled tasks in a web-based dashboard. It is designed as a development-time companion, not a production monitoring solution.

What telescope is

Telescope is a PHP package that integrates deeply with Laravel's service container to intercept and log HTTP requests, database queries, exceptions, queued jobs, notifications, and other framework events. It provides a local web UI for real-time inspection and filtering of these telemetry events, with configurable listeners and data retention.

Quickstart

Get the telescope source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/laravel/telescope.gitcd telescope# follow the project's README for install & configuration

Need it deployed, integrated, or customized instead? DEV.co ships production installs.

Best use cases

Local development debugging

Inspect incoming requests, responses, database queries, and application state in real time without adding print statements or log parsing.

Performance profiling during development

Identify slow queries, N+1 problems, and cache misses before they reach production by viewing detailed query timings and execution counts.

Integration testing and QA

Verify email sends, job queuing, notifications, and event dispatching are working correctly without relying on external services.

Implementation considerations

  • Telescope must be registered in the application service provider and configured with allowed environments (typically development only) to prevent unintended activation.
  • Database migration is required to store captured events; the schema supports customizable retention policies.
  • Gate-based authorization controls access to the Telescope dashboard; configure to restrict by IP, user role, or custom logic.
  • Listener configuration allows selective capture of specific event types to reduce overhead and noise.
  • Sensitive data (passwords, tokens, API keys) should be masked in configuration using the privacy feature.

When to avoid it — and what to weigh

  • Production monitoring required — Telescope is not designed for production use; for production observability, use dedicated APM tools (New Relic, Datadog, etc.).
  • Team-wide centralized logging — Telescope runs on local developer machines and does not provide centralized log aggregation or multi-user audit trails.
  • Zero-overhead requirement — Telescope incurs performance overhead from event listeners and data retention; disable or exclude it in performance-critical contexts.
  • Non-Laravel projects — Telescope is Laravel-specific and cannot be used outside the Laravel framework ecosystem.

Security considerations

Telescope captures sensitive request/response data and query parameters; configure privacy masking for credentials and secrets. Access to the dashboard should be restricted to trusted development environments. Local-only deployment mitigates exposure risk, but ensure the development machine and source control do not leak captured data containing secrets.

Alternatives to consider

Laravel Debugbar

Lighter-weight toolbar overlay in browser inspector; no database required but less feature-rich for complex request inspection.

Xdebug + IDE integration (PHPStorm, VS Code)

Step-through debugging with full stack visibility; steeper learning curve and not middleware-agnostic.

External APM (New Relic, Datadog, Sentry)

Production-ready observability with alerting and team dashboards; overkill and costly for local development.

telescope FAQ

Can Telescope be used in production?
Not recommended. Telescope is designed for development environments. For production monitoring, use dedicated APM or observability platforms.
Does Telescope slow down my application?
Yes, event listeners add overhead. For performance-sensitive environments, disable Telescope or selectively enable only required listeners.
How is captured data stored?
Data is stored in the application's local database or file system with configurable retention policies; no cloud storage by default.
Is Telescope safe for shared development environments?
Authorization is configurable via Gate; restrict dashboard access by IP or user role to prevent unauthorized access.
