In their own words, as submitted to SaaSHub.


Cert Decoder is a free online tool that helps you decode X.509 SSL/TLS certificates in PEM format. It instantly shows important information like the issuer, expiry date, SAN entries, and fingerprint. All data is processed locally in your browser, so nothing is ever sent or stored elsewhere.
PandaNpc is a cross-platform control plane for coding agents running on your own hardware. Run Claude Code, Codex CLI, PandaCode, DeepSeek Harness, or Pi on Windows, macOS, or Linux, then supervise the same live session from desktop, Web, iPhone, or a Chrome side panel. Unlike cloud sandboxes,...

As answered by people managing Cert Decoder and PandaNpc.
Cert Decoder's answer
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
PandaNpc's answer:
PandaNpc started from a simple observation: scaling from one coding agent to many is primarily a supervision and coordination problem. Each new agent needs somewhere to run, shared conventions and memory, a way to ask for human decisions, and tools beyond the terminal.
The product is being built around the idea that everyone should be able to have a fleet of agents working on machines they already own. PandaPaw provides local execution, Agent Center shares rules and memory, the encrypted mesh connects machines, and the Web, desktop, and iOS clients let people supervise work from anywhere. Browser and computer control, scheduled tasks, PandaNote, and MCP remove more of the per-agent overhead.
Cert Decoder's answer
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
PandaNpc's answer:
PandaNpc uses Rust for PandaPaw agent bridges and the Tauri 2 desktop core; Vue, Nuxt, and TypeScript for the Web and desktop interface; Swift and SwiftUI for iOS; and Node.js services with MySQL and Redis on the backend. Live sessions use WebSockets. The private device mesh is built on WireGuard networking, and agent integrations use the Model Context Protocol (MCP) where appropriate.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

Cert Decoder's answer
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.
PandaNpc's answer:
PandaNpc is a strong fit if you want remote control without giving up local execution. Your existing CLI agent keeps running with its repository, credentials, and toolchain on your machine while you supervise it from Web, iPhone, Windows, macOS, Linux, or the Chrome extension.
Compared with single-agent mobile companions, PandaNpc supports several coding engines and many machines in one workspace. It adds a private mesh, live approvals, Agent Center memory, notes and MCP, scheduled jobs, browser and computer control, session sharing, custom providers, and a free plan. It is especially useful when official Claude Remote Control is unavailable because you use API-key authentication, Bedrock, Vertex AI, Microsoft Foundry, or a custom base URL.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
PandaNpc's answer:
PandaNpc controls coding agents where they actually run: on your own Windows, macOS, or Linux machines. It does not move your repository into a cloud sandbox or depend on one model vendor. A single interface remotely supervises Claude Code, Codex CLI, PandaCode, DeepSeek Harness, and Pi from Web, iOS, or desktop, including live output, tool approvals, subagents, diffs, and reconnectable history.
It also combines an encrypted private device mesh, cross-engine Agent Center memory, PandaNote, scheduled tasks, browser and computer control, and 38 MCP tools. Because the bridge talks to the local CLI rather than the model provider, it also works with API keys, Bedrock, Vertex AI, Microsoft Foundry, and custom gateways.

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
