S3 Explorer — manage S3-compatible object storage from your desktop

Cross-platform Tauri + Vue 3 client supporting AWS S3, MinIO, Backblaze B2, Cloudflare R2, and 17+ other S3-compatible providers.

What's new in v0.3.2

✨ New features

• Incomplete multipart uploads cleanup — surfaces S3 multipart uploads that were started but never completed (a silent storage cost most users don't know about). A yellow ⚠ icon now appears on bucket cards in the sidebar when orphan uploads older than your configured threshold are detected. Click it to open a sortable, filterable table per bucket with single-row and bulk Abort actions, age filter (1h / 24h / 7d / Custom hours / All), live size aggregation across the orphans, and a confirm dialog before any destructive action. Universal across all 21 supported providers — uses the standard ListMultipartUploads / ListParts / AbortMultipartUpload S3 API, no provider-specific quirks. Configurable threshold under Settings → S3 / Storage → Incomplete upload threshold (hours), defaulting to 24 hours.

🛡️ License experience overhaul

• Offline grace extended from 7 days to 35 days — aligns with industry standard (Microsoft 365: 30 days, Adobe Creative Cloud annual: 99 days, Keygen.sh recommended default: 30 days) and accommodates legitimate offline scenarios such as travel, corporate firewalls, and slow-link work environments.
• Profiles are no longer auto-disabled when license downgrades. Previously, falling back to the free tier silently disabled connection profiles 6 and beyond. From v0.3.2 forward, all your existing profiles stay enabled forever — only the creation of new profiles past the free-tier limit is blocked.
• Empathetic downgrade modal at the actual transition event, with reason-specific wording for each cause (offline grace expired, server-side revocation, integrity check failure). Always reassures that profiles are intact and provides a concrete next step.
• Heads-up modal at day 30: if your license has been unable to sync for 30 days, you get a single non-intrusive notice that you have 5 days remaining, so you can plan to reconnect — no silent surprise on day 35.
• All new wording is deliberately reassuring rather than accusatory: no "license invalid" panic language, every message provides actionable guidance.

🔧 Improvements

• Fix: suppress an unused-variable compiler warning in release builds of the cache manager (cosmetic only — no behavior change).
• Telemetry: license tier sent to PostHog now uses a single shared vocabulary (monthly / lifetime) across web (purchase events) and desktop (activation events), so funnels can join correctly on the tier field.

🛡️ Security

All existing defenses are preserved unchanged: HMAC machine-binding on the license file (so the config can't be moved between machines), NTP-verified time-skew detection, anti-debug watchdog (still silent on detection by design), AES-256-GCM credential encryption, four dispersed CHECK POINTs across the codebase. The HMAC signature now also covers the new grace-warning persistence flag, so it can't be tampered with on disk.

A one-shot, transparent v2→v3 storage migration is in place: existing licensed users will simply have their signature silently re-signed on first launch of v0.3.2 — no re-activation required.
