Explainable rules
Every crawl decision can be understood before and after a run.
Archive modern websites on your Mac.
Durable, inspectable, reproducible website snapshots. Stored locally and under your control.
Native macOS website archiving
Your archive. Your rules. Your Mac.
Harbor creates durable, inspectable, reproducible snapshots without a Harbor account or hosted archive service. Choose fast HTTP crawling, deterministic Browser Mode rendering, or Smart Mode that escalates client-rendered pages when needed.
- macOS 14+
- HTTP, Browser & Smart modes
- Resumable crawls
- Local-first storage
- Safe offline preview
01 / Scope
Control exactly what gets archived.
Build ordered, typed rules with a visible default action. Test a URL before saving, preserve or normalize query strings, set depth and URL limits, include supporting assets, and keep robots.txt visible in the policy.
Bounded by design
Depth, URL count, workers, retries, request delay, and bandwidth remain explicit.
Configuration snapshots
Each run retains the rules and performance policy used to create it.
02 / Inspect
See every request and resource.
Follow queue state, workers, hosts, bytes, transfer rate, latency, retries, errors, and the sanitized current URL. Filter Requests, Site Tree, and Errors, then export a redacted structured log.
Responsive progress
See crawl state change while durable records remain in SQLite.
Request explanations
Review redirects, retries, source mode, rules, robots decisions, and stored representations.
Safe log export
Credentials, cookies, authorization values, and sensitive query values stay out.
03 / Preserve
Verify, compare, and browse offline.
Keep immutable source evidence and a separate readable offline site. Compare completed snapshots, reuse unchanged objects, inspect bounded text diffs, verify SHA-256 hashes, and export a portable folder or ZIP.
Safe Preview
Browse localized copies with live HTTP and HTTPS requests blocked.
Snapshot history
Classify new, changed, deleted, redirected, metadata-only, and unchanged resources.
Verified exports
Create folders or ZIPs with sanitized manifests, reports, and SHA-256 inventory.
Built for real archive work.
Harbor combines reliable crawl infrastructure with native macOS workflows, while keeping the archive itself local.
Resume after interruption
Durable queues, leases, retries, pause and resume, crash recovery, and explicit restart choices protect long-running work.
Archive modern sites
Browser Mode preserves rendered HTML and screenshots. Smart Mode escalates concrete client-rendering signals automatically.
Save authenticated sessions
Login Capture stores cookies only when requested, encrypted with AES-GCM and a per-project key in macOS Keychain.
Work with macOS
Use keyboard shortcuts, Quick Look, notifications, optional Finder tags, Spotlight project metadata, and native scheduling.
Replay proven settings
Templates and replay create new runs from saved roots, modes, rules, network policy, and performance settings.
Available in five languages
The in-app experience supports English, French (Canada), German, Japanese, and Simplified Chinese.
- No Harbor account, advertising, analytics, or telemetry
- Archives and exports remain in folders you select
- Saved cookies are encrypted with keys protected by macOS Keychain
- Safe Preview blocks live HTTP and HTTPS requests
Harbor for macOS
Preserve websites as evidence you can inspect.
Harbor is developed by Ateliers Underlabs Inc. for people who need durable local archives, not another hosted capture account.
