One-line Introduction

sequel-ace.com offers Sequel Ace, a free and open-source database management tool designed specifically for macOS. It is mainly used to manage MySQL and MariaDB databases. Maintained by the open-source community, it is the modern fork and successor to the classic Sequel Pro. Many users choose it because it is completely free, ad-free, lightweight, and friendly for users in China, with downloads and usage available without any special network setup.

Business Overview

Sequel Ace is not a commercial company, but an open-source community-driven project hosted on GitHub. Its predecessor was Sequel Pro, a tool once widely loved by macOS developers. Since Sequel Pro had not been updated for a long time, community developers forked the code and created Sequel Ace to fix bugs, support newer macOS versions, and add new features. The project has tens of thousands of stars on GitHub and is one of the popular choices for MySQL/MariaDB management in the macOS ecosystem. Its main “service” is providing a free, open-source, native macOS database client for individual developers, small teams, and educational use cases. As an open-source project, it does not have a traditional “industry position,” but it enjoys an excellent reputation among macOS developers and is widely regarded as the best replacement for Sequel Pro. Its users are mainly macOS-based web developers, backend engineers, data analysts, and database administrators.

Who Is It For?

Sequel Ace has a very clear target audience: developers or operations staff using macOS who need to frequently connect to and manage MySQL or MariaDB databases. It is especially suitable for individual developers and small teams, such as indie developers setting up a local LAMP environment for testing or managing databases on remote servers. For everyday tasks such as basic CRUD operations, table schema design, and running SQL queries, Sequel Ace is more than sufficient. It is not ideal for large enterprises or users who need advanced graphical features such as database designers, ER diagrams, or performance monitoring dashboards. It is also not suitable for users who need to connect to other database types such as PostgreSQL or SQLite. In short, if you are a macOS user, rely on MySQL in your daily work, and value a free and lightweight tool, Sequel Ace is built for you.

Key Features and Highlights

• Completely free and open source: Released under the MIT license, with no paywalls, ads, or feature restrictions. The code is fully public and auditable.
• Native macOS experience: Built with Swift and Cocoa, offering an interface that closely matches macOS design, smooth performance, and low memory usage.
• SSH tunnel support: Built-in SSH connection support makes it easy to securely access remote databases via a bastion host without extra terminal configuration.
• Fast querying and editing: Supports syntax highlighting, autocomplete, multi-tab queries, and intuitive inline editing of table data.
• Connection management: Lets you save multiple database connection profiles and securely store passwords in Keychain, making database switching quick and convenient.
• Export and import: Supports exporting to formats such as SQL and CSV, and can directly run SQL files to import data, covering basic migration needs.

Pricing Analysis

Sequel Ace costs zero dollars and is completely free. Among similar macOS database management tools, this is the lowest possible price tier. Other well-known competitors such as Navicat and TablePlus require paid licenses, with annual fees ranging from tens to hundreds of dollars, usually licensed by device or user. Sequel Ace has no hidden costs, in-app purchases, or subscriptions. If you do not need enterprise-grade advanced features, its value for money is extremely high, since you get a stable and actively maintained basic database client at no cost. The only “cost” is that it only supports macOS and only works with MySQL/MariaDB. If you need cross-platform support or support for multiple database types, the advantage of being free becomes less compelling.

How Chinese Users Can Use It

For users in China, Sequel Ace is very easy to use. First, network accessibility is excellent: the project is released on GitHub, and users in China can directly visit its GitHub Releases page to download the .dmg installer. Download speeds may be slower in some regions, but this can be solved with mirrors or proxy tools, and no “VPN” is required for normal use. Second, payment methods are irrelevant because it is free. Sequel Ace itself does not provide invoices because it is not a commercial product. If you need reimbursement documentation, you could try contacting GitHub or the relevant community, but in most cases an official invoice will not be available. This may be inconvenient for users who need to go through a company reimbursement process. Comparable alternatives in China include the free and open-source DBeaver, which is cross-platform and supports many database types, and the paid Navicat for MySQL, which has more complete features but is much more expensive. Overall, Sequel Ace has almost no barrier to use in China.

Pros and Cons

Pros:

• ✅ Completely free and open source, with no feature restrictions or ads
• ✅ Native macOS app with lightweight performance and a polished interface
• ✅ Supports SSH tunnels and Keychain for secure and convenient access
• ✅ Active community, frequent updates, and timely bug fixes
• ✅ Can be downloaded and used directly from China without special network access

Cons:

• ❌ Only supports macOS; Windows/Linux users cannot use it
• ❌ Only supports MySQL/MariaDB, not PostgreSQL, SQLite, or other databases
• ❌ Lacks advanced features such as visual ER diagrams, database designers, and performance analysis dashboards
• ❌ No official invoice support, making it less suitable for formal enterprise procurement that requires reimbursement
• ❌ No built-in team collaboration or permission management features

Comparison with Similar Products

The main products competing directly with Sequel Ace include Sequel Pro (no longer maintained, but still used by some users, with older functionality), TablePlus (paid, supports multiple databases, has a beautiful interface and a free trial, but with feature limitations), and DBeaver (free and open source, cross-platform, supports almost all mainstream databases, but its interface is not as native-feeling as Sequel Ace). In comparison, Sequel Ace’s biggest strengths are that it is free, native to macOS, and focused on MySQL/MariaDB. TablePlus stands out for multi-database support and more modern features. DBeaver’s advantages are cross-platform support and broad database coverage. If you only use macOS and MySQL, Sequel Ace is the best free option. If you need cross-platform or multi-database support, DBeaver is more suitable. If you are willing to pay for more features and a more polished experience, TablePlus is worth considering.

Final Recommendation

Sequel Ace is best suited for this scenario: you are an independent developer or small-team member using macOS, and your daily work mainly revolves around MySQL/MariaDB, so you need a free, lightweight, low-friction database management tool. It is fully capable of handling everyday data browsing, querying, editing, and simple import/export tasks. It is not suitable if you need to connect to multiple database types, require team collaboration features, or must provide an official invoice for company reimbursement. The recommendation is to download the free version directly from GitHub and try it at zero cost. If its features meet your needs, you can comfortably use it long term without paying. If you later need more advanced features, then consider upgrading to a paid tool.
