~/products/stallscope

StallScope

An always-on monitor for Windows that lets you find out what froze the machine, after the fact. It starts before the symptom does and keeps recording every second — down to each CPU core and each drive as its own series, never averaged together — so “it just locked up” is something you can read back later.

How it is delivered: A desktop app for Windows. The app itself is obtained from the Microsoft Store. You subscribe to Pro by going from the app’s settings screen to a Stripe checkout page (we do not use Microsoft Store in-app purchases).
System requirements: Windows 10 version 1809 or later, x64. No administrator privileges are required. The interface is in Japanese only
What is free: There are no limits on the recording side. Collection every second, every metric including each CPU core and each drive individually, stall detection, the analysis report, markers, recording the process name of the foreground app, high-frequency process sampling around a stall, and writing out the daily summary are all free. Only the features that interpret those recordings are paid.
Price — Pro (monthly): Monthly ¥100
Payments from outside Japan are charged at $1 (USD).

+ Before-and-after reports for a fix (what changed, and by how much, between before and after)
+ Exporting an anonymised report for sharing
+ Long-term trends and a monthly summary
+ From the moment you subscribe, everything already recorded is readable too (there is no need to start collecting again)
Price — Pro (yearly): Yearly ¥1,000
Payments from outside Japan are charged at $10 (USD).

+ The same features as the monthly plan. Paying yearly saves the equivalent of two months
Payment method: Credit card (processed by Stripe)
Timing of provision: Available immediately after payment completes (the corresponding features are enabled in each service). For products where we deliver a licence key by email, we send it within one business day to the email address you registered when you subscribed.
Cancellation: You can cancel from “Manage subscription” in the app’s settings screen, which opens the Stripe customer portal. You can cancel at any time. After cancelling, you will not be billed again, and you can keep using the service until the end of the period you have already paid for.
Refunds: We do not issue prorated refunds. Where the cause lies with us, such as a payment failure, we will handle it individually.

~/products/gridge

Gridge

A database client for Windows where each connection carries its own strength. It handles SQLite, PostgreSQL and MySQL in a single grid, and a connection registered as production is opened read-only, so a write never reaches the database.

How it is delivered: A desktop app for Windows. The app itself is obtained from the Microsoft Store. You subscribe to Pro by going from the app’s licence screen to a Stripe checkout page (we do not use Microsoft Store in-app purchases). The licence key is sent within one business day to the email address you registered when you subscribed.
System requirements: Windows 10 version 1809 or later, or Windows 11 (64-bit). The interface is available in Japanese and English (it follows your OS display language)
What is free: Connecting to one database and reading and writing to it safely stays free. The per-connection safety modes (development, staging, production), the affected-row estimate, transaction control, the checks and formatting that run before a statement, the cell viewer, and exporting to CSV and TSV are all free. What is paid for is crossing between environments, reading more deeply, and recording things to reuse.
Price — Pro (monthly): Monthly ¥300
Payments from outside Japan are charged at $3 (USD).

+ Query plan visualisation (only EXPLAIN is sent, so looking at a plan never runs the statement), ER diagrams, and jumping to related rows
+ Schema diff between two environments and DDL generation (anything that drops a table or column comes out commented)
+ Statistics views, and an activity monitor that watches running queries over a second connection
+ An audit log that keeps every statement with its connection and safety mode, searchable later by text
+ Exporting to JSON, JSON Lines, Markdown tables and INSERT statements, plus saved queries with parameters
Price — Pro (yearly): Yearly ¥3,000
Payments from outside Japan are charged at $30 (USD).

+ The same features as the monthly plan. Paying yearly saves the equivalent of two months
Payment method: Credit card (processed by Stripe)
Timing of provision: Available immediately after payment completes (the corresponding features are enabled in each service). For products where we deliver a licence key by email, we send it within one business day to the email address you registered when you subscribed.
Cancellation: You can cancel at any time. After cancelling, you will not be billed again, and you can keep using the service until the end of the period you have already paid for.
Refunds: We do not issue prorated refunds. Where the cause lies with us, such as a payment failure, we will handle it individually.
