LEVELUPSOFT INC. · ON-PREMISE BY DESIGN
Build with our microservice framework and AI-driven SDLC, automate with enterprise workflows, and let AI bots become the front door to your business — handling chat and voice, inbound and outbound, and acting directly on your internal systems. All of it runs on your own infrastructure, even air-gapped.
Products
Enterprise solutions are installed on your own servers. Personal apps and developer tools are ready to download. Each card links straight to the product site.
The foundations for development, automation and collaboration, installed on your servers.
Describe the table, get the service
A pure-Java microservice framework with a code-generation Studio. It generates service code from a table spec by rules, so AI and people work on the same standard code.
AI agents build, and review each other
A self-hosted SDLC platform where AI agents plan, implement, review and wait for human approval. Every decision and its evidence is kept as an audit record on your server.
Your code doesn't live on someone else's server
A self-hosted code repository with repos, issues, code review and wiki in one set. Keep using your git commands, and read Subversion history alongside.
Your developers' Claude Code, anywhere, via your own server
A Remote Web IDE for enterprise and individual developers. Put a relay on your company server and watch and control CLI sessions running on each Mac from a desktop browser or phone: send prompts, approve permissions, or stop a run.
Workflow automation, enterprise grade
A self-hosted automation platform that joins screens, files, workflows and AI agents. Kafka-based distributed execution and automatic Saga compensation handle air-gapped and high-volume workloads.
Chat and voice AI bots become the first point of contact — connected to your internal systems.
AI bots at the front door of every task
A platform for building and orchestrating AI bots that serve employees and customers over chat and voice. They answer inbound inquiries, reach out proactively, and connect to your internal systems to go from lookup to completion. Every conversation and record stays on your servers.
Services, apps and free tools you can download and use right away.
A messaging service anyone can sign up for and use right away.
Important news, as fast as it gets
A fast, secure messenger inspired by the Joseon-era pabal relay. An independent MTProto-compatible service, so existing bot libraries work by changing only the address.
Buy once on the App Store and keep it. No subscriptions, no ads.
Your OTP codes, opened only by your fingerprint
A menu-bar two-factor authenticator for Mac. Secrets are sealed in the Secure Enclave and open only with Touch ID. The app has no network permission, so nothing leaves your Mac.
Your favorite fonts, now on iPhone
Import OTF, TTF and TTC fonts, preview them and install via an iOS configuration profile. Ships with 16 free fonts such as Pretendard.
See as you write, draw as you diagram
A Mac Markdown editor with live preview, Mermaid, KaTeX and PDF export. Edit diagrams visually in Diagram Studio.
Free tools that take a little weight off a developer's day.
Korean documents, into Markdown AI can read
A CLI and MCP server that converts HWP, HWPX, PDF and other official documents to Markdown and structured JSON, and builds official HWPX from Markdown. Works in air-gapped networks.
JSON at a glance, as code and tree
A browser extension that shows code and tree views side by side to edit and validate JSON. No account and no server; it runs entirely in the browser.
Markdown that reads well the moment it opens
A Chrome extension that renders .md files instantly and lets you edit and preview in split view. Your documents are never sent anywhere.
Heritage
Levelupsoft began in 2023 with Simple F/W & Studio, an OSGi-based MSA development platform. Building on that design, we spent the next two to three years creating a new product line for the AI era.
A REST API-based DAO client, a network F/W for legacy TCP/IP, a web-based source generator, and common services and modules.
A gateway to manage and operate REST APIs with OAuth 2.0 support, a file-transfer gateway, and an internal integration server for the business zone.
Source management, continuous integration and delivery, automated testing, Docker and Kubernetes deployment, and data security.
That experience carried forward into Simple Framework, SSemWorks and SSemProHub for the AI era.
About
Levelupsoft listens to customers first, then builds the solution they need in the simplest structure that works. We believe being useful matters more than being clever.
Code, conversations and business data belong to the customer. We design for on-premise and air-gapped installs first.
Rule-based structure gives the same output for the same input, so people and AI read and edit the same code.
We build the tools developers use daily and feed that experience back into our enterprise products.
