AltaCoda

Markbase turns the coding agents your team already uses into a software factory. It puts agents to work on tickets, production alerts and scheduled tasks using your team’s processes, machines, checks and reviews.

Markbase works with Claude Code, Codex, Cursor, Antigravity CLI and Pi. Team knowledge stays readable and editable outside any single agent, so it stays with the team when people or coding agents change. Markbase is available as a hosted service, self-hosted in the customer’s environment, or as a dedicated deployment in the customer’s cloud.

Clearlane Tests

Clearlane Apps

Clearlane Tests adds test management to Jira Cloud without new work item types. Versioned test cases store steps, test data and expected results, and link to the requirement work items they cover. A coverage view acts as a requirements traceability matrix and identifies requirements with no test case. Plan a campaign for each version or sprint, then run tests step by step. Each run records the exact test case version, pass/fail results and comments for each step, plus the tester and date. A failed step becomes a Jira bug with reproduction steps in one click. Closing a campaign seals it with a fingerprint. Optional electronic signatures record the name, date and time, and meaning; later changes void the signatures. PDF reports include the summary, coverage, results and history. Import test cases from CSV. The app helps teams maintain verification records for IEC 62304, ISO 13485 and 21 CFR Part 11. It runs on Atlassian Forge, so data stays in the customer's Atlassian site.

specgit

FnFirst

specgit is a visual editor for teams writing together in GitHub. It handles Git so product managers, UX researchers, technical writers, and teammates can write and format docs as they would in a document editor. Each save becomes a commit under the writer's GitHub name. Teammates can edit the same file live and leave inline comments. When a doc is ready, specgit opens a pull request for engineers to review in GitHub. Review reads the whole doc and leaves comments; Triage fixes them and closes the threads. Nothing changes until you approve it. Teams can also use specgit with Obsidian vaults; saved files retain Obsidian's exact format. GitHub remains the source of truth, and specgit does not keep copies of documents or comments. The Free plan includes one repository and five publishes per month, with no credit card required. Pro costs $8 per editing seat per month; viewing and commenting are always free.
