Windmill
Pros
- + Script-first model: typed functions become endpoints, jobs and flow steps with auto-generated UIs — my nightly pipeline was rebuilt in one Docker session
- + Free self-hosted tier carries unlimited executions, not a trial disguised as a plan
- + Rust execution engine kept orchestration overhead sub-second between flow steps in my tests
- + Worker-group model scales throughput with replicas and tag routing instead of redesigns
- + Transparent per-unit Enterprise pricing ($20/builder, $10/non-builder, $50/worker) with published SLA terms
Cons
- - Zero no-code path — teams without developers cannot use it at any price
- - Prebuilt Community Edition images bundle proprietary Windmill Labs terms (no resale/wrapping/modifying), separate from the AGPLv3 source build
- - Worker groups and role configuration have a real learning curve before the platform pays off
- - Small vendor (under twenty employees in 2024 reporting, ~$15M raised) relative to the incumbents it replaces
- - Flow durability is lighter than Temporal for mission-critical long-running orchestration
Trigger.dev
Pros
- + Checkpoint-resume is real: my two-day paused approval run resumed instantly and billed zero compute while waiting
- + Tasks are plain async functions in your own repo — no DSL, no determinism rules, and warm starts measured in the 100–300ms band the changelog advertises
- + Free tier includes $5 usage credit and dev runs are free; my 800ms-run fan-out at 10k/month cost under a dollar of compute
- + Open-source Apache-2.0 with the same codebase on Cloud and self-hosted, and an unusually active release line (v4.5.12 as of August 2026)
- + Full workflow surface built in: retries, queues, scheduling, idempotency, priority, lifecycle hooks, wait tokens and AI-SDK tool integration
Cons
- - TypeScript/JavaScript only — Python and Go teams are simply not served
- - Production self-hosting means Postgres, Redis, webapp and worker containers plus a build tunnel; the docs get thin exactly where ops gets hard
- - The plan fee is a usage credit, not a ceiling — LLM-heavy agent runs can outrun the included allowance without cost modelling
- - v3 is shut down on Cloud (old triggers and deploys no longer run), and the v3→v4 migration has sharp edges for busy projects
- - Concurrency and log-retention limits bite early (1-day logs on Free), and the 'AI agents' marketing outruns what is fundamentally an execution platform
