Devin vs Agent.so

Devin plans and executes real engineering work across your repos, from bug fixes and PR reviews to multi-week migrations. You assign tasks in natural language, and Devin investigates the codebase, writes changes, runs tests, and opens pull requests your team can review and merge. It targets engineering teams with complex, multi-repo codebases who want parallel agents instead of another autocomplete sidebar.

Standalone coding assistants live inside your editor and suggest the next line. Devin runs as autonomous agents in secure cloud VMs (Devin Cloud) or through Devin Desktop, a full IDE and command center that evolved from Windsurf. The product routes work across frontier models from Anthropic, OpenAI, Google, and Cognition SWE models, and plugs into GitHub, Linear, Slack, Datadog, Jira, and hundreds of other tools.

Teams at Nubank, Itaú, Ramp, Harvey, and NVIDIA use Devin for code migrations, vulnerability remediation, incident triage, and long-running refactors. Enterprise deployments add VPC hosting, SAML SSO, audit logs, and MultiDevin fleets where manager agents coordinate worker agents in parallel.

Agent.so puts hundreds of role-specific AI agents and a custom agent builder behind one login. You chat with pre-built experts spanning marketing, coding, tutoring, and dozens of other fields, create your own agents in seconds without code, and train them on your files, links, and sitemaps. The platform routes chats through models from OpenAI, Anthropic, Google, Meta, xAI, DeepSeek, and other labs so you are not tied to a single chatbot subscription.

Most agent builders hand you a blank canvas and expect you to wire prompts yourself. Agent.so front-loads the library with 250+ ready-made agents, an Apps Hub for one-shot tasks like subject lines and ad copy, and a Shards currency for pay-as-you-go access to advanced models and skills. That structure suits people who want specialist chats on day one rather than a week of setup.

Freelancers, consultants, and small teams use Agent.so for marketing drafts, coding help, and training agents on client knowledge bases. Agent Plus costs $19 per month at the early-access rate (regular $29) and includes unlimited messages, custom agent training, and 3,000 monthly Shards. A free tier remains available with conversation depth limits and caps on how many custom agents you can run at once.
