Compare / Amp vs Stack AI
Head-to-head
Amp vs Stack AI.
Side-by-side on ratings, pricing, pros, cons, and the honest take on which to pick. Cross-category comparison: Amp is a coding agent and Stack AI is a ai application builder.
| Amp | Stack AI | |
|---|---|---|
| Rating | 4.0 / 5 | 3.5 / 5 |
| Category | Coding Agent | AI application builder |
| Tech level | developer | low code |
| Open source | No | No |
| Pricing | Free tier with usage limits. Paid tiers via Sourcegraph subscription. Bundled with Sourcegraph Code Search for teams already on the platform. | Freemium. Team plans from $199/month. |
| Best for | Engineering teams already paying for Sourcegraph Code Search who want to add an AI agent that reuses the existing codebase index. Free tier is generous enough for individual evaluation. | Ops teams who want AI agents over their internal documents — SOPs, contracts, product specs, Notion wikis. |
| Not for | Teams not on Sourcegraph — the standalone story is less differentiated than Claude Code or Augment. Builders who want a simpler CLI experience. | External-facing automations or multi-step process workflows — n8n handles those better for most teams. |
Our verdict on Amp
Sourcegraph's agentic coding tool built on years of code-search investment. Strong for teams already on Sourcegraph; less compelling as a standalone.
Full Amp review →Our verdict on Stack AI
Best for internal knowledge base and document Q&A agents. Handles SOPs, contracts, and Notion wikis well. Strong in its lane, expensive outside it.

What works
- Built on Sourcegraph's mature code-search and indexing infrastructure
- Free tier with meaningful usage allowance
- Strong codebase-context story without separate indexing setup
- Native integration with Sourcegraph Code Search
- Sourcegraph's enterprise compliance story (SOC 2, on-prem options) carries over
What doesn't
- Standalone value less compelling than Claude Code or Augment for non-Sourcegraph teams
- Newer to agentic coding than competitors with longer track records
- Smaller community vs Cursor or Copilot
- Locked into Sourcegraph as the indexing/context layer
- Best fit narrows to teams already paying for Sourcegraph
Stack AI
What works
- Best-in-class document ingestion and RAG pipeline
- Strong enterprise data connectors (Notion, Confluence, Google Drive)
- SOC 2 compliant
- Good UI for non-technical configuration
What doesn't
- Expensive at team scale ($199+/month)
- Limited flexibility for multi-step process automation
- Weaker for external-facing or trigger-based workflows
Which to pick
We'd default to Amp (4.0/5 vs 3.5/5) for most builders. Pick Stack AI if you fit its best-for case specifically: ops teams who want ai agents over their internal documents — sops, contracts, product specs, notion wikis.
Honest middle: most serious operators end up using more than one tool. If you're early in your AI agent journey, our five-question picker recommends a starting platform from your specific situation.
