Inngest
Multi-language durable workflows and AI agents that run on your existing infra
What is Inngest?
Inngest is a workflow and durable-execution platform for AI agents, background jobs, and long-running endpoints, with SDKs for JavaScript, Python, Go, and Kotlin. It wraps your functions in Steps to handle retries, flow control, and observability, and runs against any compute (edge, serverless, or servers). Used by SoundCloud, Replit, ElevenLabs, and Resend.
Tools for building, hosting, testing, observing, connecting, and giving memory or computer access to AI agents.
See the full Agent Infrastructure guide to compare more tools, buyer criteria, and related workflows.
Use cases to evaluate
Orchestrating multi-step AI agent workflows with retries
Fan-out/fan-in event processing at high throughput
Cron and scheduled jobs across languages
Durable webhook handlers with replay and observability
Fit to evaluate
Polyglot engineering teams (Python + TS + Go)
High-volume event-driven products needing >100k/sec
Healthcare/fintech teams needing HIPAA BAA
Backend teams replacing fragile queue + cron setups
Business fit
Right for you if your stack mixes Python and TypeScript (or Go/Kotlin) and you want one orchestration layer across all of them. Skip if you're TypeScript-only and prefer a tighter, single-language DX. Distinctive: handles 100K+ executions per second and offers a HIPAA BAA, so it's a realistic fit for high-throughput regulated workloads. Execution pricing tiers down sharply with volume (from $0.00005 to $0.000015 per execution).
How to evaluate Inngest
Use this category when a business wants agents that do work across tools, APIs, browsers, and data sources.
Confirm the exact workflow
Map Inngest to one concrete workflow first, such as orchestrating multi-step ai agent workflows with retries. Avoid buying before the owner, trigger, output, and success metric are clear.
Check category fit
Compare tool-calling, memory, browser automation, evals, observability, and deployment controls.
Compare practical alternatives
Shortlist Inngest against Orgo, Browser Use, Browserbase so the decision is based on fit, effort, and workflow ownership rather than brand recognition alone.
Validate cost and rollout effort
Hobby: $0/mo (50k executions, 5 concurrent steps, 3 users). Pro: from $75/mo (1M executions included, scales to 20M, 7-day trace retention). Enterprise: custom (SAML/RBAC, audit trails, 90-day retention). Execution overage: $0.00005 (1M-5M tier) down to $0.000015 (50M-100M). Events: 5M/mo included on Pro, $0.50 per additional 1M. Also confirm implementation time, support needs, and whether the technical setup matches your team.
