AI Bug Fixer — Powered by Claude Sonnet 4.5

Paste your error log.
Get the fix.

Ripper reads your stack trace and returns a surgical patch in under five seconds. No Stack Overflow. No context-switching. Just code that works.

ripper — bash
$ ripper --fix
# Paste your error...
Traceback (most recent call last):
File "app.py", line 42, in get_user
NameError: name 'user' is not defined
''' ROOT CAUSE '''
Variable user referenced before assignment. Likely a refactor
residue from renaming to current_user — line 41.
''' FIX '''
+ current_user = get_current_user(request)
✓ Fixed in 3.4s — copy the line above.

From crash to commit
in three moves.

01

Paste the carnage

Drop in your error log, stack trace, or broken code. Any language, any framework. Ripper speaks fluent Python, JS, TS, Go, Rust, Java, C#, Ruby, PHP, Swift and more.

02

Ripper diagnoses

Claude Sonnet 4.5 analyzes the root cause and writes the minimal patch. You get a two-sentence diagnosis before the patch so you actually learn something.

03

Copy. Ship. Win.

Get the fixed code with a tight explanation. No lectures. No fluff. History is saved so you can search, copy, and reuse fixes across projects.

Sub-5-second fixes

Claude Sonnet 4.5 returns surgical patches before you switch tabs. The average fix time across all users is under five seconds.

Stack-trace native

Designed to read raw exceptions. No formatting required. Paste the raw output from your terminal, no cleanup needed.

Private by default

Your code is never used to train. Each fix is a fresh session. We don't store, analyze, or learn from your errors.

Root-cause first

Get a two-sentence diagnosis before the patch lands. You debug faster when you understand what's actually broken.

History on tap

Every fix saved automatically. Search, copy, and re-use across projects. Your debugging history is always one search away.

Multi-language

Python, JavaScript, TypeScript, Go, Rust, Java, C#, Ruby, PHP, Swift, and more. One tool for your whole stack.

How Ripper stacks up

No subscriptions, no seat limits, no context window theatrics. Here's the deal.

Ripper $19/mo Cursor $20/mo GitHub Copilot $10/mo
Target use Bug fixing only — paste error, get fix General-purpose AI coding assistant General-purpose AI coding assistant
Fix speed < 5 seconds — single-turn diagnosis + patch Multi-turn chat; Agent Mode adds latency for complex fixes Tab-completion speed; multi-file fixes require back-and-forth
Stack-trace input Raw paste — no cleanup, no formatting needed Works but optimized for code, not error logs Works in chat but expects conversational context
Bug-fixing specialty Built for this. Root-cause diagnosis first, patch second. Agent Mode handles multi-file fixes — powerful but broad Inline suggestions + PR review; not purpose-built for bugs
Context window Full error + relevant code — no arbitrary cap 10,000 tokens — best-in-class for large codebases ~2,000–4,000 tokens depending on plan
Multi-file fixes Handles cross-file bugs in one pass Composer handles multi-file — best-in-class Limited; requires manual orchestration
Autonomy model AI diagnoses → patches → you review. No babysitting. Agent Mode: full autonomy on multi-step tasks Human-in-loop; AI suggests, human applies
Free tier Full access for 14 days, then $19/mo 1,000 requests/mo on free plan 60 completions on trial
Team / seat limits Unlimited seats — same flat price $40/user/mo for Business $19/user/mo for Business
Privacy Code never used to train; fresh session per fix Privacy mode on Business plan (code not stored) IP indemnity included on Business/Enterprise
Fix history Auto-saved, searchable across all projects Snapshot history on Pro Limited to Copilot Chat conversation history
Key differentiator Purpose-built for one job: kill the bug and explain why it happened Autonomous multi-file Agent Mode — best generalist AI coder Deep GitHub + IDE integration; strongest enterprise compliance
