Uptime monitoring, status pages and on-call in one place. Create and tune monitors for HTTP, TCP, DNS, ping, TLS certificates, domain expiry, heartbeats and scripted browser logins. Run a check on demand, read uptime and response-time history, acknowledge and resolve incidents, post incident updates, schedule maintenance windows and edit public status pages. Read-only until you grant write access.
AI-native observability and security for engineering teams and coding agents. Search production logs in plain language, investigate issues and root causes, and create or edit live dashboards in your Sazabi workspace. Requires a Sazabi account (OAuth, or a secret key via the X-Sazabi-Secret-Key header).
Vigilia watches your live app, explains every problem in plain language and writes the fix prompt. Your AI fixes it; Vigilia confirms with real traffic. Vigilia watches web apps that are live with real users, including apps built with Lovable, Bolt, v0, Cursor and Claude Code. It catches errors, failed requests and downtime, explains each problem in plain language, and writes a fix prompt for it. Connect Vigilia to Claude and ask what's broken. Claude lists your open incidents worst first. For each one it reads the plain-language diagnosis, who it affects, the technical evidence (error, page, failing request, stack frames and what the visitor did right before) and Vigilia's fix prompt. In Claude Code or another coding agent, Claude can then fix the cause in your own codebase. Once you've deployed, it marks the incident fixed, and Vigilia watches real traffic to confirm the error stayed away. If it comes back, the incident reopens as a regression. You can also ask how an app is doing (uptime, open incidents, today's traffic), get the exact install snippet for a new project, and check that a live site is running Vigilia. Vigilia never reads or changes your code: the fixing happens in your session, by your AI, in front of you. The only tool that changes anything is marking an incident fixed (the install check just records its result on the app), and you can connect with read-only access. Your data is stored in the EU. Emails, tokens and card numbers are stripped from what visitors' browsers send, and only that scrubbed error context is sent to Anthropic to write the diagnosis. Requires a Vigilia account. The free plan covers one app; reporting backend errors (Supabase, Next.js routes, Workers) is part of Pro.
Hundreds of pay-per-call tools for agents: company records, screening, validation, web reading.
Search your mobile, web and server app logs session by session, and read grouped errors, daily stats, releases and alerts.
Trust layer for AI agents. Privi Guard checks web pages, emails and tool results for prompt injection and outgoing text for leaked API keys and card numbers, with signed on-chain receipts (1,000 free checks a month). Privi Scan grades any MCP server for tool poisoning and rug pulls. Plus tamper-evident audit logs, agent passports, spending mandates and a live kill switch.

Game observability for Three.js, Phaser, Babylon.js, PlayCanvas, Unity, Godot, Unreal and GameMaker games. Ask what's wrong with your game and get ranked findings from real players' sessions: frame-time spikes by level, errors with the gameplay just before them, where players die, version comparisons, store reviews and each game's own dashboard. Sign in with your Glitchless account (OAuth); a new workspace can start on a demo game.
Read-only MCP server for diagnosing any WordPress site — security, performance, forms, logs, downtime — with evidence. The connector exposes no write operations and your AI never sees the site's credentials (secrets are redacted before output). Built for agencies managing many client WordPress sites. Free for 1 site.
