About

Harness Cosmos Software Factory Agent is a cloud-based AI agent platform for automating software engineering workflows from an issue or event through code changes and pull requests. Teams can configure agent workflows with specialized experts, execution environments, triggers, integrations, and human approval checkpoints. Workflows may start from ticket updates, pull requests, alerts, schedules, or webhooks; agents can investigate a task, plan a change, write code and tests, open a pull request, and respond to review feedback. A code context engine retrieves relevant information from a codebase, while sandboxed virtual machines provide an execution environment. Software engineering and platform teams can use Cosmos to coordinate agent-driven implementation, review, verification, and related development work, with shared organizational memory, workflow versioning, audit history, and controls for automation budgets.

About

Mesrai is a multi-agent AI code review platform for engineering teams. Five specialist agents (Bug, Security, Performance, Architecture and a team Playbook agent) review every pull request, backed by a graph of your codebase that traces the impact of each change across monorepos and multiple repositories. Reviews are posted inline with severity rankings and suggested fixes, and Mesrai also tracks DORA metrics for engineering health. Bring your own LLM key and pay your provider directly. Reviews run in ephemeral sandboxes and your code is never used for training. Available with a VS Code extension, a CLI and MCP plugins.

Pros & Cons from Real Users

Pros

  • The whole-repo context makes the difference. On a Flask PR it flagged a delete route using GET as a CSRF risk, explained why a link or image tag could trigger it, and gave a confidence score with a before/after fix.
  • Mesrai reviews pull requests with context from the whole repository, so its comments go beyond the lines that changed. We currently using it for our dev team since 1 year. I especially like the Jira/Linear ticket check / custom review rules / the CLI / bringing our own model key; keep only what you actually use. It is quick to set up on GitHub/GitLab.

Cons

  • Young product with a short track record. The suggested-change button replaced one line with a whole function, so I applied the fix by hand from the before/after snippet.
  • It is a newer product with a smaller community and fewer third-party reviews than established tools.
