TraceMaker

Trace is an AI-powered browser developed by Breadcromb that creates a private knowledge layer by unifying tabs, documents, and conversations and uses that context to assist the user. The product is described as local-first by default and is offered as a free download.

agenttrail is a local, open-source observability layer for AI coding agents. It watches plans, tool calls, file changes, and progress from Claude Code, OpenAI Codex, Cursor, or other agents that edit files, then presents them as a live project map with repository components, dependency arrows, progress, and working, blocked, or completed states. It compares declared agent intent with observed filesystem activity, including renewed changes to supposedly finished work, and displays the current run, task list, streaming tool activity, elapsed time, recent calls, session plans, and a live repository tree. The tool runs locally through commands such as `npx agenttrail`, with no account, global installation, or telemetry. `npx agenttrail init` adds the agenttrail convention to CLAUDE.md and AGENTS.md, creates a starter PLAN.md, and installs additive local Claude Code hooks; the resulting plan and file activity are used to generate a map of roughly 5–9 repository components with dependencies and verifiable statuses. It supports one daemon per repository, a shared board tab switcher, restart via `npx agenttrail up`, and login autostart through `npx agenttrail autostart`.

Amagine3D is an open-source 3D capability layer for hardware creation, developed by Amagine. Its parametric CAD workflow turns natural-language hardware requirements, reference images, and key dimensions into editable enclosures and assembly structures around internal components, producing Python and build123d source code alongside STEP, STL, or color-aware 3MF exports. A 3D-native agent first organizes the requirements into a design brief, then runs the generated source in a browser geometry runtime. It uses the resulting model state and check results for dimensions, part connectivity, interference, and motion clearance to revise or accept the design. The workflow supports multipart structures such as covers, hinges, and latches, including assembly clearances and printing tolerances. Generated parameters can be adjusted in the workbench and written back to the source without regenerating the model. The system can preview, measure, modify, and save complete designs and their check reports.

MTL Explorer is a self-hosted GPS track and trail log for a personal computer, NAS, home lab, or server. It imports Garmin, GPX, and FIT tracks, displays thousands of activities on maps, calculates track statistics, replays routes with a cinematic 3D camera, and supports route planning through BRouter. The application is distributed as a Docker Compose stack with a Spring Boot backend, a Vue 3 and TypeScript progressive web app, an OpenAPI schema, and optional sidecars for BRouter, local vector maps, and GeoNames SQLite location search. It is licensed under AGPL-3.0-or-later, with a separate commercial license for users who do not want to comply with the AGPL terms.

modelprint is a browser-based tool for fingerprinting OpenAI-compatible API endpoints and investigating which model or serving infrastructure may sit behind an alias. It sends controlled probes and compares results side by side, including normalized tokenizer counts for English, CJK, code, and rare Unicode inputs; template offsets; validation messages and error codes; maximum-output refusals; finish-reason vocabulary; router metadata; generation records; response headers; provider path behavior; context-window classes; and logprob geometry. The tool runs without installation, a build step, or a server: API calls go directly from the browser to the provider, with keys retained in the browser tab. It can pin models to provider hosts to reduce routing noise and labels signals reported or validated by a router. Its documentation cautions that matching fingerprints indicate shared infrastructure or a model family rather than proving model identity, and that probes may report missing signals when headers, logprobs, or other telemetry are unavailable. The project supports community-authored probes through a defined JavaScript contract and is released under the MIT license.
