PLAINCODE合同会社 is a company based in Shibuya, Tokyo, Japan, established in January 2023. Its business covers the planning, development, and operation of online services, Web content production and maintenance, and internet advertising. Its core product is DIRECTLY, a direct contracting platform for freelance engineers and companies. The platform emphasizes that no agency intermediary is involved from project matching through contract completion, with “0 yen in intermediary commissions.” The company also provides commissioned services such as Web system development, EC site development, and Web consulting.
Based on the available content, DIRECTLY is closer to an engineer supply-and-demand matching and contract facilitation platform than a developer tool in the traditional sense, such as a code editor, CI/CD system, monitoring platform, or API development tool. Its value for developers lies in helping freelance engineers find projects and sign directly with companies; for companies, the value is reducing intermediary layers and potentially lowering outsourcing costs. The site does not disclose supported programming languages, frameworks, engineer vetting mechanisms, contract templates, project management features, APIs/SDKs, or third-party integrations, so its technical ecosystem and automation capabilities cannot be assessed.
The page clearly states that DIRECTLY has “no agency commission” and “0 yen in intermediary commissions,” which is its clearest selling point. However, the main content does not explain whether the platform charges companies posting fees, subscription fees, success fees, or whether it charges engineers membership fees. Therefore, it can only be confirmed that there is no intermediary commission; the overall cost of use cannot be inferred further. No price ranges are provided for commissioned development, EC site development, or consulting services either, so inquiries are likely required.
The main advantage is its clear positioning: directly connecting companies with freelance engineers, reducing the fees and communication layers found in traditional agency models. The company also has Web development and consulting capabilities, which may allow it to support clients with a combination of talent sourcing and delivery. The downside is the limited public information: there is a lack of detailed product pages, service guarantees, explanations of the contract process, case studies, customer reviews, documentation, and technical integration information. For enterprise procurement, the platform’s scale, talent quality, compliance practices, and payment/settlement mechanisms still need further verification.
It is suitable for companies looking for freelance engineers in the Japanese market, as well as Japanese freelance developers who want to bypass agencies and take on projects directly. It may also fit clients who need Japanese-language communication, Web system development, or EC site development. The main content does not mention access from China, so it is not possible to determine whether it can be reached directly. There is also no information about payment methods, cross-border contracts, or Chinese-language support. If a China-based team needs a similar service, it may be worth comparing Japanese platforms such as Lancers, CrowdWorks, and Workship, as well as domestic alternatives such as 程序员客栈 and 码市.
