    Image for Runsight

    Runsight — YAML-first workflow engine for AI agents. Design agent workflows visually. The canvas writes YAML to your filesystem — commit it, diff it, review it in PRs like any other code. When something breaks at 2 AM, you don't restart and hope. You pause the running agent, edit the prompt, and resume. No redeployment. What makes it different: → Git-native. Workflows are YAML files in your repo, not rows in a database. → Per-run cost tracking. Know what every agent call costs before the invoice arrives. → Runtime intervention. Pause, inspect, fix, resume — while the workflow is running. Built for engineering teams who run agents in production and need the same rigor they have for everything else: version control, code review, and the ability to kill a runaway process. Open source. Self-hosted.

    Image for act101

    act101 is an AI-powered developer tool built for semantic code refactoring, structural analysis, and cross-language migrations. Instead of relying on fragile whole-file rewrites, it gives AI coding agents AST-aware operations that understand programming languages at a structural level. The platform supports 163 programming grammars and provides more than 180 refactoring operations, including extracting functions, renaming symbols, moving modules, generating code, and reorganizing imports across entire repositories with consistency and undo support. The platform works as an MCP-native server designed for AI coding environments like Claude Code, Cursor, Codex, and OpenCode. Developers can connect act101 directly to their AI agents so those agents can perform real semantic code transformations instead of generating approximate edits from raw text. One of act101’s biggest advantages is language-aware refactoring. The tool can help AI agents refactor projects written in Python, Rust, TypeScript, Go, Ruby, Java, C, COBOL, Elixir, and many other languages. Because operations are AST-aware, formatting, comments, imports, and project structure stay intact during changes. Every operation also includes automatic checkpointing and instant undo functionality. The platform also specializes in large-scale language migration workflows. Developers can use act101 to port projects such as C to Rust, Ruby to Elixir, COBOL to Java, PHP to TypeScript, or Python 2 to Python 3. Instead of treating migration as a simple conversion task, act101 introduces structured migration workflows using contracts, inventories, dependency ordering, manifests, and migration state tracking. This approach helps teams reduce behavioral drift, dependency issues, and migration confusion in large enterprise codebases. act101 includes deep repository analysis capabilities as well. The platform provides over 30 analysis tools that inspect coupling, dead code, hotspots, architectural boundaries, dependency cycles, migration readiness, and type completeness. AI agents can use these analyses to understand the structure of a codebase before making modifications. This helps reduce risky edits and improves automated engineering workflows. The platform is highly optimized for token efficiency when used with AI coding systems. Instead of loading entire files into an AI context window, act101 returns only the relevant AST-derived slices of code. According to its benchmarks, some operations reduce token usage by more than 95%, helping AI agents stay within context limits while working on large repositories. Another major focus is security and local execution. act101 runs as a single native Rust binary with no plugin runtime, no dependency graph, and no cloud-based code uploads. Code stays on the developer’s machine, minimizing supply-chain risks and protecting private repositories. The tool parses projects on demand without indexing or caching, ensuring results stay fresh and synchronized with the codebase. The platform offers multiple pricing tiers. A free plan supports personal and open-source use with query tools and basic refactoring operations. Paid plans unlock commercial licenses, advanced analysis features, structural operations, and premium language support. Enterprise offerings focus on large-scale migration projects and autonomous AI agent fleets operating across production systems. Overall, act101 positions itself as infrastructure for AI-native software engineering. Instead of AI merely suggesting code changes, the platform enables agents to perform reliable, semantic, and reversible engineering operations directly on real-world codebases.

    Image for TemplateCat

    What is this? A little cat that helps you pick professionally designed templates. Just joking! It means "templates by categories". When doing web design for clients (eg. a dentist website), I often need to compare templates across different website builders. Jumping between platforms was really annoying, so I made this tool. Where are the templates from Framer Webflow Squarespace (Will add Figma Sites and Readymag later, I guess 10k+ templates in the future) What are the features? High quality templates - I only choose from website builder products where they hire professional designers. Browse by categories/features/styles - eg. find "portfolio" or "minimalist" templates On-page preview + device switching - directly see desktop/tablet/mobile effects Website builder pricing listed - easy to compare costs (Coming soon: pricing range filters, merge similar tags) Simply put: saves time jumping between different platforms to find templates.

    Image for Expressify Ai

    Expressify is a 24/7 AI assistant built for service companies that need to respond to customers faster, capture more leads, and book more jobs automatically, whether you have a full customer service team or you're running the whole operation yourself. Most service businesses lose jobs the same way: a customer reaches out, nobody responds fast enough, and they've already booked with a competitor by the time someone gets back to them. It's not a marketing problem. It's a speed problem. The business that responds first wins the job the majority of the time, and most service companies simply can't respond fast enough when staff are tied up on calls, out in the field, or the office is closed for the evening. Expressify solves this by putting an AI assistant on the front line of every customer interaction. The moment a customer reaches out through your website chat, email, or other channels, Expressify responds instantly, answers their questions, captures their contact information, and moves them toward booking an appointment. For businesses with existing staff, Expressify works in tandem, handling the overflow when agents are busy on other calls, covering after-hours inquiries, and ensuring no customer ever hits a dead end. For smaller operations without a dedicated team, it acts as a full-time virtual assistant that never clocks out. This makes Expressify valuable for any business where customer inquiries, lead response, and appointment booking drive revenue. HVAC companies use it to capture furnace calls at 9pm. Plumbers use it to respond to emergency requests on weekends. Electricians, roofers, landscapers, pest control companies, cleaning services, and home improvement contractors use it to ensure every inbound lead gets an immediate, professional response regardless of when it arrives. Beyond the trades, any service-based business including medical offices, salons, legal services, auto repair, and fitness studios that relies on customer inquiries and appointments can put Expressify to work immediately.
