Carapace
This app securely transfers sensitive information to your OpenClaw host. It encrypts secrets locally using advanced cryptography, allowing safe transmission even over unsecured channels. Ideal for users prioritizing local-first secret management.
- Local-only security
- Secure secret encryption
- QR code key generation
- Live scan/photo import
- No backend or cloud sync
- On-device encryption with Libsodium

Carapace is a local-only security companion for OpenClaw. Carapace helps you move sensistive secrets into your OpenClaw host safely, even over insecure chat channels. How it works: 1. OpenClaw generates a public key and shows it as a QR code (or ask your agent to send it to you) 2. In Carapace, you load that key by live scan, photo import or paste 3. You enter any secret (API key, token, password etc) 4. Carapace encrypts it locally and copies a payload: carapace:v1:ciphertext. 5. You paste that payload into your message channel and send it to your OpenClaw 6. OpenClaw decrypts locally and stores the secret on the host Security Model: No backend No cloud sync No Firebase No network calls from Carapace Encryption is done on device with Libsodium sealed-box cryptography. Requirements: 1. OpenClaw host companion package: @oakroadapps/openclaw-carapace-vault 2. OpenClaw host setup is required for decryption/import (add to your soul.md) Ideal for users who want a lightweight, local-first way to provision secrets into OpenClaw without pasting plaintext into chat.

Verdict
The clearest difference is review sentiment: Carapace at 100% against Breadpad's 33%. Carapace also leads on rating (5.0 vs 3.9) and in-app purchases (none vs 3). Breadpad's advantage is ratings volume (166 vs 1) and device support (4 vs 2). On price and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Breadpad sells 3 in-app purchases, starting at $4.99 per month. Carapace asks for nothing beyond the download.
Carapace holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: Breadpad has 166 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 33% of Breadpad's written reviews are positive against 100% of Carapace's.
