Pulumi (open source engine and Pulumi Cloud) · Real innovator
Pulumi ranks #5 of 28 infrastructure automation tools in the Infrastructure Automation Ledger 2026, with a Ledger Index of 61.2 out of 100. Pulumi pairs a stable Apache 2.0 engine in seven languages with a fast-moving cloud service whose tiers, prices and AI agent changed several times in 2026.

What the Ledger says
Pulumi's engine has not changed its licence or its major version since 2021, and the language and authoring score has been near the top of the group since 1.0. What moves is the cloud service: ESC, Insights, Deployments and Neo arrived as vision items, and in 2026 the tiers, prices and the AI agent all changed within four months. The commercial risk score sits below Terraform's because the engine is Apache 2.0 and the owner is unchanged, and above OpenTofu's because self-hosting, drift remediation and compliance packs are gated to paid editions. Check the state backend decision first: leaving Pulumi Cloud for a self-managed backend gives up ESC, Deployments and Neo, and no export path to another IaC tool is documented.
Pulumi is the only product in this group with an in-product agent that writes and applies changes, and the only one that bills AI by the token. The buyer-side gap is proof: no dated GA post for Neo, no stated GA for the MCP server, and the benchmark that supports the claims is the vendor's own.
Capability by area
Buying, lock-in and release record
Buying and licence (commercial risk)(lower is better)
- Price and licence volatility3.5
- Engine licence unchanged; the cloud service added per-token Neo pricing (2026-06-17), renamed every tier (2026-09-21) and repriced Enterprise (2026-09-28)
- Purchase constraints2
- Free edition for one user; self-hosting only on Enterprise at $2,000 a month; compliance policy packs and SCIM on Enterprise only
- Channel and access1
- Open source CLI, self-serve signup, AWS Marketplace listing; partner terms not published
- Owner stability2.5
- Independent venture-backed company; last funding round found is 2023; no acquisition
- Cost of staying supported2
- No version windows to manage; paid support add-ons from $625 a month (tracker, not read at Pulumi)
Technical lock-in(lower is better)
- Formats2
- Programs in general-purpose languages; JSON checkpoint state is documented
- Export path2.5
- No documented export to another IaC tool; the conversion path runs into Pulumi, not out of it
- Stack coupling0.5
- Any backend (Pulumi Cloud, S3 and compatible, Azure Blob, GCS, PostgreSQL, local file)
- Hardware / cloud coupling1.5
- Pulumi Cloud is the default and hosts ESC, Deployments, Neo and Insights; self-managed backends cannot recover from some partial failures
- Skills and tooling coupling1.5
- Ordinary programming skills plus the Pulumi resource model
Release credibility
- Cadence4
- A minor roughly every week (3.266.0 on 2026-09-30 to 3.269.0 on 2026-10-15); the rhythm is visible but not published
- Roadmap transparency3
- Open repository, changelog, blog and release notes; no dated roadmap found
- Say-do3
- ESC went from preview to GA in 11 months; Insights 2.0 and Neo have no dated GA announcement, so one of three trackable previews is clearly closed
- Velocity4.5
- Many capabilities a month across the engine, Deployments and Neo
- Lifecycle stability2.5
- One rolling 3.x line with no forced upgrades, but no support policy page and tiers renamed twice in 2026
Partners and services
- Partner programme openness2.5
- Partners page lists cloud, technology and integrator partners; no tiers, criteria or certification stated
- Multi-tenancy and self-service3.5
- Organisations, teams, RBAC with custom roles (25 on Pro, unlimited on Enterprise), SCIM on Enterprise, templates
- API and infrastructure-as-code4.5
- REST API plus the Automation API in Node.js, Python and Go
- Skills and certification2
- No certification found; general language skills are common, Pulumi-specific experience is rarer
