Vapi
What is Vapi?
Vapi runs phone agents that answer support lines, qualify leads, schedule appointments, and place outbound sales calls with sub-500ms response times. Engineering teams configure voice, conversation flow, telephony, and integrations in one platform that has handled over one billion calls for customers including Amazon Ring, Intuit, and ServiceTitan.
Building phone agents usually means stitching together telephony, speech-to-text, an LLM, text-to-speech, and call routing yourself. Vapi bundles those layers with squads, warm transfers, live tool calling, MCP access, and 200+ model integrations so engineering teams ship production voice flows through one API instead of five vendors.
Vapi targets engineering teams shipping production voice agents and enterprises that need compliance, uptime guarantees, and dedicated support. Scale customers get SSO, RBAC, SOC 2, HIPAA, PCI, data residency, and a dedicated account team.
Devin
What is Devin?
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.
