Point Observer at a codebase and get one production-health report: static analysis, dependency CVEs, runtime errors, logs, and AI explanations. No server, no account, no instrumentation. One binary, fully offline.
observer analyze ./my-project --out report.htmlOther tools each cover one slice. Observer correlates code, runtime, and logs — then explains them.
Language, framework, database and infrastructure — identified with evidence.
Secrets, SQL injection, XSS, SSRF, path traversal, dangerous config — severity + fix.
A drop-in agent captures live exceptions and groups repeated failures.
Mines existing logs for frequency, repeated failures, and likely causes.
Root cause, impact, exploitability, and a fix — grounded in the findings.
One ~13 MB binary. No server, no agent to deploy, no account. Runs in air-gapped environments where SaaS tools can't.
Security & Code-Health scores, CWE / OWASP tags, and a PCI-DSS / ISO 27001 mapping — plus SARIF, JSON, CSV and PDF export.
A quality gate, baseline ("new issues only"), and a GitHub Action put findings in the Security tab and on pull requests.
Observer is a private audit snapshot, not a replacement for full semantic SAST or production monitoring. It combines curated local checks and optional local engines in one report.
| Observer | Full SAST | Cloud security | Production monitoring | |
|---|---|---|---|---|
| Primary job | Private audit snapshot | Deep continuous code analysis | Managed hosted analysis | Live errors and telemetry |
| Setup | One local binary | Local, server, or cloud setup | Account and cloud workflow | Application instrumentation |
| Analysis depth | Curated heuristics + optional local engines | Deeper semantic analysis | Varies by vendor | Runtime rather than source audit |
| Offline use | Default; enforceable | Available in some products | Usually cloud-dependent | Usually cloud-dependent |
| Best fit | Client audits, handovers, air-gapped work | Large continuous programs | Managed security programs | Operating live applications |
Use Observer when privacy, fast setup, and a readable point-in-time report matter. Use deeper SAST for broad semantic analysis, centralized policy, or large-team governance. The tools can complement each other.
Open-core: the full CLI and the local dashboard are free forever. Pro add-ons are a one-time purchase — buy only what you need.
