For SaaS founders

Your competitors are shipping
audit trails. Are you?

Every day without them is a support ticket you'll answer, a deal you won't close, and a user who quietly churns.

🎫

Kill the "what happened?" ticket

"Did my payment go through?" "Who changed that setting?" — these questions land in your inbox every day. Audit trails answer them before they're asked.

Watch your support volume drop.
🔒

Close deals you're currently losing

Enterprise buyers ask for audit logs before they sign. Compliance teams require them. With Logtrail live, you stop losing deals to a checklist item.

Turn a blocker into a differentiator.
📈

See your product through your users' eyes

Every log is a data point. Which features get used at 2am? Where do users drop off? Your audit trail becomes a single source of truth.

One integration. Two audiences. Zero blind spots.

Audit trails aren't a compliance checkbox — they're the difference between users who tolerate your product and users who trust it.

Trust compounds. So does churn.

Stop reinventing the wheel

Build audit logs yourself:
6 weeks. Or use Logtrail: 5 minutes.

Your startup has a hundred things to build. Audit trails shouldn't take weeks of engineering time.

❌ Building it yourself

  • Week 1: Design the schema & DB tables
  • Week 2: Build the logging API
  • Week 3: Create the UI components
  • Week 4: Add search & filtering
  • Week 5: Handle retention & cleanup
  • Week 6: Bug fixes & edge cases
6+ weeks of dev time

✅ With Logtrail

  • Minute 1: Sign up (1 click via Google)
  • Minute 2: Copy your API key
  • Minute 3: Add one line of code
  • Minute 4: First log appears live
  • Minute 5: User activity feed is live
  • Forever: Retention & search managed for you
Under 5 minutes total
What you're comparing

Not Datadog. Not boring logs.
The Stripe for audit trails.

User-facing audit trail infrastructure — lightweight enough for indie hackers, powerful enough for serious SaaS teams.

❌ Traditional logging tools

Built for engineers, not users.

Complex dashboards, query languages, and alert fatigue — designed for SRE teams at scale.

  • Query languages only engineers understand
  • Alert fatigue from infrastructure noise
  • Internal use only — users never see it
  • Requires dedicated DevOps knowledge
  • Weeks of setup and configuration
  • Not built for user-facing transparency
✅ Logtrail

User trust infrastructure for SaaS.

Beautiful activity feeds your users actually see, with the developer ergonomics you need.

  • One line of code, zero config
  • Search that just works, instantly
  • User-facing transparency built in
  • Live in under 5 minutes
  • AI-native — your agent integrates it
  • Made for indie hackers & small teams

FAQ

Common questions about
adding audit logs to SaaS

How long does it actually take to integrate?
Under 5 minutes for the first log. Sign up with Google or GitHub, copy your API key, and call log.info() anywhere in your app. Your first event appears instantly.
Can my AI coding assistant (Cursor, Claude, etc.) integrate it?
Yes. Logtrail is AI-native by design. We publish an llms.txt and AGENTS.md so AI coding assistants can discover and integrate our API automatically.
Is the free plan actually free, or are there hidden limits?
The free plan is genuinely free forever — 5,000 logs per month, 21-day retention, 1 project. No credit card required. You only pay when you need more.
Does this replace Datadog / New Relic?
No — and it's not trying to. Datadog and New Relic are for internal DevOps observability. Logtrail is for user-facing audit trails: giving your customers a transparent view of their own activity.
What frameworks and languages are supported?
Logtrail is a REST API, so it works with any language. We have SDKs and guides for Node.js, Python, and more. The API is dead simple — a single POST request with a JSON payload.

Ship with confidence.
Give your users transparency.

Add Logtrail to your app in under 5 minutes.
