Spacelift - Pros & Cons
Pros
- ✓Concurrency-based pricing is dramatically cheaper than Terraform Cloud's per-resource model — users report 3-5x cost reductions on real workloads
- ✓Genuine multi-IaC support means you manage Terraform, Ansible, and Pulumi stacks in one platform instead of three separate tools
- ✓OPA policy-as-code integration gives real teeth to infrastructure governance — not just advisory warnings, actual blocking policies
- ✓Private workers run in your VPC with outbound-only connections, solving the 'state leaving our network' problem cleanly
- ✓The free plan includes enough to evaluate with a real project — not just a 14-day trial that pressures you into buying
- ✓Strong customer support with dedicated Slack channels and CSMs on Business/Enterprise plans — users consistently praise responsiveness
Cons
- ✗Custom pricing with no published numbers makes it impossible to estimate costs without talking to sales first
- ✗Overkill for small teams — if you have 2 developers and 50 resources, Atlantis or vanilla Terraform Cloud may be simpler
- ✗The learning curve for OPA policies is real: Rego is a niche language that most teams need to learn from scratch
- ✗Some users report rough edges with permission models, particularly around state locking and maintainer access
- ✗No transparent pricing comparison possible — you have to get quotes from both Spacelift and competitors to compare
- ✗Audit trail is Enterprise-only, which means compliance-focused mid-market teams get pushed to the most expensive tier
E2B - Pros & Cons
Pros
- ✓Strong isolation via Firecracker — safe enough for fully LLM-generated code
- ✓150ms cold-start is fast enough for interactive chat-style agents
- ✓Drop-in ChatGPT-style Code Interpreter SDK with persistent Jupyter kernels
- ✓Desktop sandbox makes browser-use and computer-use agents practical
- ✓Production-proven (Perplexity, Hugging Face) and well-instrumented
Cons
- ✗Per-hour pricing can balloon for long-running autonomous agents
- ✗Pro tier only includes 20 hours/mo — most teams burn through it
- ✗Smaller per-sandbox resource limits than running on your own GPU box
- ✗No GPU access on standard sandboxes (use Modal or RunPod for that)
