- 01
Sidegent
Sidegent teaches AI concepts through interactive lessons, graded agent labs and browser-accessible cloud machines. Its tutor and coding assistant help learners work with actual agent frameworks inside the lessons.
Best for: Relevant to beginners who want guided exercises and are willing to inspect generated code and grading feedback.
- 02
LockIn MCP
LockIn MCP connects compatible assistants to timed domain blocking on the user’s computer through a desktop installer and MCP relay. An optional Chrome extension adds task-aware page checks and focus-session controls.
Best for: Relevant to desktop users who want an assistant to start bounded focus sessions and can manage system permissions.
- 03
EmailJS
Developers configure templates, parameters, attachments, and spam protections, then trigger sends from browser or mobile code via the EmailJS SDK.
Best for: Front-end and full-stack developers who need simple transactional mail from static sites or SPAs.
- 04
Codebuff
Codebuff is a terminal-native AI coding agent that indexes entire repositories in seconds and edits code or runs commands from natural-language instructions. It emphasizes deep project awareness, surgical multi-file edits, and optional pay-as-you-go credits alongside STRONG usage subscriptions.
Best for: Developers who prefer CLI control and want an agent that maps dependencies before editing large codebases.
- 05
DocuPilot
DocuPilot is a GitHub App that automatically generates and updates README, CHANGELOG, and API documentation when you push code. It reads push diffs only, opens pull requests for doc changes, and supports configuration through a .docupilot.yml file in each repository.
Best for: Developers and teams who want doc maintenance tied to git pushes rather than manual README edits.
- 06
Pre.dev
pre.dev is a long-horizon coding agent that plans, builds, and verifies software over extended runs in the browser or terminal. It connects to many SaaS tools, publishes previews, and sells separate RL coding tasks to AI labs through pre.dev Labs.
Best for: Developers and teams who want an autonomous coding agent with planning, verification, integrations, and optional enterprise RL task sourcing.
- 07
Freestyle
Freestyle provides full Linux VMs purpose-built for long-running AI agents with millisecond startup, live cloning, pause/resume, nested Docker, and custom networking. Developers use the VMs for coding agents, browser automation, and containerized workloads.
Best for: Teams building autonomous agents that need persistent Linux environments, previews, and Docker inside the VM.
- 08
Dropstone
Dropstone combines a coding CLI and web assistant with account memory and remote MCP tools. Higher tiers advertise computer use, parallel agents and personalized actions such as smart-home control or phone calls.
Best for: Relevant to builders who need an agent across coding and research surfaces with inspectable action approvals.
- 09
FACEIO
FACEIO is a passwordless facial authentication SDK for websites and apps, combining face recognition, liveness detection, and age verification through a browser widget and REST API. Developers enroll users once and authenticate them with face scans instead of passwords.
Best for: Web developers who need cross-browser face login, liveness checks, or age gates without building biometrics in-house.
- 10
CodeGuide
CodeGuide turns product ideas or existing GitHub repositories into spec-driven documentation kits with PRDs, tech stacks, wireframes, and task plans for AI coding tools. It also offers a Chrome extension and an autonomous Software v2 agent for multi-model doc generation and coding workflows.
Best for: Builders using Cursor, Windsurf, or similar agents who need structured specs before autonomous coding.
