How it works

From error to fix
in three steps

No setup. No configuration. Just drop in your logs and get actionable intelligence immediately.

01
Upload or Paste

Drag & drop any log file — .log .txt .json .csv .xml — or paste your stack trace. Supports files up to 700K characters.

02
AI Analyzes

Our AI parses every line, counts exact occurrences, identifies distinct error types, and traces root causes — in seconds, not hours.

03
Get Code Fixes

Receive side-by-side before/after code patches for every error, inferred from your stack traces, with numbered steps and prevention tips.

Features

Everything your team needs
to build without fear

Severity Ranking

Errors ranked Critical → High → Medium → Low, sorted by occurrence count. The most impactful issue always surfaces first.

AUTO-SORTED
Occurrence Counting

Exact count of how many times each distinct error appears. Know whether you're facing a rare edge case or a systemic failure.

ACCURATE COUNTS
Root Cause Analysis

Goes beyond the symptom. Identifies the underlying code path, missing null check, misconfiguration, or resource leak.

DEEP ANALYSIS
Code Patch Suggestions

Side-by-side before/after diffs inferred from your stack traces — even without seeing your source code. Works across 12+ languages.

12 LANGUAGES
Team Collaboration

Share analysis history across your organization. Every team member sees the same ranked errors, root causes, and fixes.

What engineers say

Loved by teams who move fast

“We had a production incident at 2am. ErrorLens identified the root cause — a missing null check in the payment flow — in 6 seconds. We shipped the fix in 12 minutes.”
AM
Staff Engineer · FinTech
“The before/after code diffs are genuinely impressive. It inferred our exact service architecture from the stack trace and gave us patches that worked first try.”
SK
CTO · SaaS Platform
“Our junior developers used to spend hours on stack traces. Now they paste the log, get the analysis, and ship the fix. It levelled up the entire team's debugging ability.”
