## About Observer

Observer is a local code audit tool that scans a codebase and produces a production-health report covering security, code quality, dependencies, runtime errors and logs. It runs from the command line in one step, for example by pointing it at a project folder and writing an HTML report. The site states that source code stays on the user's computer and that no account, server or source-code upload is required for the default offline mode.

The tool combines several kinds of checks in one report. It identifies languages, frameworks, databases and infrastructure, and runs static analysis to flag secrets, injection risks, unsafe configuration and risky patterns. Rule-based guidance explains the context and impact of each finding and suggests possible remediation. An optional local agent can capture and group application errors, and log analysis reviews repeated failures and likely causes from existing logs. Reports can be exported as HTML, JSON, CSV, SARIF and printable formats, and teams can use baselines, quality gates and GitHub Actions in their pipeline.

Observer is aimed at developers, consultants, agencies and teams who need private audits of client or legacy code. The Community Edition is free and open source and includes offline CLI auditing, built-in rules, a local dashboard and a watermark on reports. Observer Pro is a paid all-access annual subscription, listed at $89 per year, that adds native PDF reports, scheduled scans and other professional features.

## About PaperTrack

PaperTrack is a web app for sharing PDFs, decks, contracts and other documents through trackable links. Senders see when a document is opened and how long each page is read, with dwell-time heatmaps that show which pages hold attention.

Access can be controlled per link. Senders can require a verified email passcode, add password protection and expiration dates, restrict viewers by email domain, and require a click-through NDA. Dynamic watermarks stamp each recipient's email, IP address and date onto the pages, and links can be revoked at any time. Higher plans add comments, download protection and virtual data rooms.

It is aimed at founders sending pitch decks, sales reps sending proposals, and legal or M&A teams sharing contracts. A free plan covers single-seat sharing with page analytics.
