- Significant configuration overhead — expect 4–8 hours of setup
- No managed UI — CLI-only, not accessible to non-technical stakeholders
- Lower task completion rate on complex, multi-file work
- GPT-4 API costs accumulate at high task volume
- Ongoing engineering maintenance required for self-hosted infra
Best Use Cases for Each Agent
| Scenario | Best Choice |
|---|---|
| Funded startup with $500+/mo dev tooling budget | Devin ✓ |
| Open source project, zero budget | SWE-Agent ✓ |
| Enterprise requiring strict data residency | SWE-Agent ✓ |
| Non-technical founder delegating engineering tasks | Devin ✓ |
| Research team benchmarking agent architectures | SWE-Agent ✓ |
| Automated GitHub issue triage at high volume | SWE-Agent ✓ |
| Async Slack-driven development workflow | Devin ✓ |
Devin wins when your team needs zero-friction autonomy and can justify the cost through productivity gains. Based on our benchmarks across 50k+ lines of code, Devin saves approximately 3–4 hours of developer time per resolved issue — at Team plan pricing, that’s a positive ROI if your developers bill or cost at $75+/hr.
SWE-Agent wins when cost efficiency and customization outweigh polish. At ~$2/issue with GPT-4, it delivers strong value for engineering teams already investing in DevOps tooling — and for any organization where code must never leave internal infrastructure.
Alternatives Worth Considering
| Tool | Price | Best For |
|---|---|---|
| GitHub Copilot | $10–39/mo | IDE autocomplete + PR summaries |
| Cursor | $20–40/mo | AI-first IDE with multi-file editing |
| OpenHands (OpenDevin) | Free (OSS) | Enterprise-ready open-source agent |
| Claude Code | $20–200/mo | Terminal-native agent, strong reasoning |
| Windsurf | Free–$25/mo | Lightweight AI-assisted coding flows |
If neither Devin nor SWE-Agent fits your workflow today, Cursor or GitHub Copilot offer lighter-weight AI assistance without the full autonomous agent overhead. For more comparisons, see our AI Tools category.
OpenHands (formerly OpenDevin) sits squarely between SWE-Agent’s DIY approach and Devin’s managed service. It’s enterprise-ready, actively maintained in 2026, and free to self-host — worth a serious evaluation before committing to Devin’s pricing model.
FAQ
Q: What is the real pricing difference between Devin and SWE-Agent?
Devin starts at $20/month (Core, pay-as-you-go) with the Team plan at $500/month including 250 ACUs — each ACU covers ~15 minutes of active agent work. At 3–5 ACUs per bug fix, expect $6–10 per resolved issue. SWE-Agent is free to self-host; running it with GPT-4 costs approximately $2 per issue via OpenAI’s API. Factor in 4–8 hours of initial engineering setup for SWE-Agent that Devin does not require. See current rates at (Devin’s pricing page).
Q: Can I switch from Devin to SWE-Agent without losing workflow continuity?
There’s no direct migration path — these are fundamentally different architectures. The transition requires configuring a self-hosted environment, selecting an LLM provider, and adapting from Devin’s task-based UI to SWE-Agent’s CLI-driven interface. Budget 1–2 weeks of senior engineering time for a smooth switch. On the positive side, both tools are GitHub-centric, so your existing issue history, PRs, and codebase transfer naturally without any conversion work.
Q: Does SWE-Agent support models other than GPT-4?
Yes — SWE-Agent’s extensible architecture supports multiple LLM backends including Claude (Anthropic), Gemini (Google), and any OpenAI-compatible model. This LLM flexibility is one of its most significant advantages over Devin, which is locked into Cognition Labs’ proprietary model. Using Claude with SWE-Agent may yield stronger performance on reasoning-heavy refactoring tasks. Check the SWE-Agent GitHub repo for current supported model configurations.
Q: Is Devin suitable for open source projects with no budget?
No — Devin does not offer a sustained free tier beyond an initial trial. For open source projects with zero tooling budget, SWE-Agent is the clear choice; it’s fully free to self-host. Alternatively, GitHub Copilot offers free access for verified open source maintainers, which covers the most common autocomplete and PR assistance use cases without autonomous agent complexity.
Q: How does Devin handle code privacy and enterprise data security?
Devin operates in a cloud-hosted workspace managed by Cognition Labs — your code and task data pass through their infrastructure. This may not satisfy strict data residency requirements (GDPR-regulated environments, certain HIPAA-adjacent workloads). For organizations with hard data sovereignty requirements, SWE-Agent’s self-hosted deployment is the stronger option since no code leaves your infrastructure. Devin does offer enterprise plans with custom security agreements — contact their team directly at (devin.ai) for specifics.
📊 Benchmark Methodology
| Metric | Devin | SWE-Agent |
|---|---|---|
| Task Completion Rate | 68% | 53% |
| Code Accuracy | 82% | 74% |
| Avg. Time per Task | 18 min | 24 min |
| Cost per Resolved Issue | ~$6–8 | ~$2 |
| Context Understanding | 8.5/10 | 7.5/10 |
| First-Use Setup Time | ~15 min | 4–8 hours |
Limitations: Results reflect our specific codebase structure and task complexity distribution. Performance will vary based on LLM choice (SWE-Agent), network conditions, and task type. Devin model updates post-April 2026 may alter these figures.

Final Verdict: Which AI Agent Wins in 2026?
After 30+ days of real-world testing, the Devin vs SWE-Agent decision comes down to one core trade-off: managed polish vs. open-source flexibility.
Choose Devin if your team wants zero-configuration autonomy, can absorb $500+/month, and regularly tackles complex, multi-step engineering tasks. The 68% task completion rate and ~15-minute time-to-productive delivers genuine ROI for funded startups and enterprise teams — especially those delegating to Devin via Slack without direct code access.
Choose SWE-Agent if you’re budget-conscious, technically capable, or require full data sovereignty. At ~$2/issue with GPT-4, it’s the obvious choice for open-source projects, research environments, and cost-sensitive engineering teams. The 53% task completion rate is real — but on well-scoped GitHub issues, the gap narrows considerably.
Start with SWE-Agent to validate that autonomous coding fits your team’s workflow — cost is zero. If you hit its limits on complex multi-file work or need non-technical stakeholders to manage tasks, upgrade to Devin. Both are GitHub-native, so the transition is straightforward.
