Redaction happens locally — nothing raw leaves your browser

Stream DevTools from every tab.
Secrets redacted before upload.

Send console logs, network requests, and errors to Cursor, Claude Code, or Cline — from all your tabs at once. JWTs, API keys, emails, and tokens are redacted locally in the extension before anything leaves your machine.

The Problem

Your AI Token Bill Is Out of Control

Teams using their own API keys with AI IDEs are watching costs skyrocket. Browser logs are a major culprit — here's why:

API Costs Are Exploding

Claude Sonnet 4.5 costs $15/M output tokens. GPT-4.1 isn't cheap either. Browser logs can burn through $20 of API credits in a single debug session.

Context Window Bloat

The same error 500 times? Each one eats your 200k context. Agent loops with repetitive logs can waste 150k tokens on noise alone.

Cursor's New Pricing Hurts

Cursor moved to usage-based pricing. What cost $50/mo now costs $200-250/mo for heavy users. Every wasted token hits your wallet.

AI Performance Degrades

Bloated context = worse responses. Your AI struggles to find the actual bug buried under thousands of duplicate stack traces.

AI Context Window (Before Keylock Bridge)

[ERROR] TypeError: Cannot read property 'map' of undefined at App.tsx:42

Who It's For

Built for Developers Who Pay for Their Own Tokens

Solo developers and teams using their own API keys with AI IDEs — Keylock Bridge can reduce your browser log tokens by up to 95%.

Primary Use Case

Developers & Teams with API Keys

Up to 95% fewer browser log tokens

Using Cursor, Claude Code, or Cline with your own OpenAI/Anthropic API keys? You're paying for every token — including thousands of duplicate log entries. Keylock Bridge compacts browser logs before they hit your context window.

The Pain:

API bills climbing as AI usage grows
Context windows filling up with duplicate errors
AI responses degrading from noisy context

The Solution:

Smart compaction can reduce browser log tokens by up to 95% (depending on how noisy your app is). Example: thousands of tokens of log noise become clean, actionable signal.

QA Teams & Cross-Device Debugging

Stream logs from any device to any developer's AI

QA finds a bug on their machine, staging server, or BrowserStack instance. Instead of copying logs manually, they stream directly to the developer's AI IDE. The AI sees exactly what QA sees — in real-time.

The Pain:

"Can you send me the console output?" back-and-forth
Logs lost in Slack threads and email chains
Time wasted on "works on my machine" debugging

The Solution:

Cross-device log streaming with E2E encryption. QA installs the extension, streams to your IDE, and your AI assistant debugs in real-time. Works with BrowserStack, Sauce Labs, VMs, and any browser.

Features

Built for Developers & Teams Who Pay for Tokens

Using your own API keys? Every feature is designed to cut costs, improve AI responses, and streamline debugging — whether you're solo or on a team.

Smart Compaction Engine

Up to 95% Fewer Tokens

Our compaction algorithms pre-process browser logs before they hit your context window — reducing noise and maximizing signal for your AI.

Error Grouping

Example: 500 identical errors → 1 summary with count. That's ~14k tokens saved.

Network Log Filtering

Keep API calls, drop asset requests. Focus on what matters for debugging.

Smart Redaction

Automatically strips sensitive data (API keys, tokens, emails) before it reaches the AI.

Anomaly Detection

Coming Soon

Surfaces unique issues, filters repetitive noise. Better signal = better AI responses.

Team-Configurable Rules

Coming Soon

Set org-wide thresholds: Top K errors, merge windows, status code filters.

Under the Hood: Advanced Capabilities

Beyond compaction — powerful features that make your AI debugging experience even better.

Large Log Offloading

Never Overflow Context

When logs exceed ~100KB, they're automatically uploaded and replaced with a compact preview + link. Your AI gets the signal without the bloat.

Token-Aware Previews

Smart Context Management

Before sending logs to your AI, we estimate token counts and build intelligent previews. You see exactly what the AI will receive.

Secrets Detection & Reporting

Know What Was Redacted

After redacting sensitive data, we provide a summary: how many JWTs, API keys, and AWS credentials were filtered — without exposing the actual values.

Multi-Tab Streaming

Debug Complex Workflows

Stream logs from multiple tabs at once. Perfect for debugging OAuth flows, microservice frontends, or multi-page checkout processes.

Zero DevOps Overhead

No Servers to Manage

No localhost servers, no port conflicts, no config files. Install the extension, sign in, done. Your whole team can onboard in minutes.

Works With Your Stack

Cursor, Claude Code, Cline & More

Any MCP-compatible IDE works out of the box. Available for Chrome and Firefox. Same account, same features everywhere.

💰 Example ROI

Example: If your team makes 100 AI requests/day with browser logs, significant token reduction could translate to meaningful savings on your API costs.

(Your mileage varies based on how noisy your logs are.)

FAQ

Frequently Asked Questions

Everything you need to know about Keylock Bridge.

It depends on how noisy your browser logs are. You can see up to 95% token reduction on apps with lots of duplicate errors or verbose logging. If you're a heavy Cursor/Claude Code user, the savings can add up quickly — but your mileage will vary. The 7-day free trial lets you see your actual savings before paying.
