Greptile Alternative: MCP Code Graph

This page is for teams that use Greptile for AI code review, or evaluated it, and now want an agent to hold the code graph while it writes, not only once a pull request exists. Both products index your codebase into a graph and both speak MCP, so it is easy to assume they compete head to head. They sit at different points in the same workflow: Greptile's graph serves its reviewers at review time, and Symvanta's graph is the thing your agent queries while it edits. For the wider category, see code graph MCP servers compared.

What Greptile does

Greptile is an AI code reviewer. It builds a graph of each repository (files, functions, dependencies), then runs a swarm of parallel agents over each pull request: the agents review the diff, assess its impact beyond the diff, and post findings such as multi-file logic bugs, security risks, and style violations (Greptile agent page, graph docs). Reviews carry a 0-5 confidence score, a summary, and generated diagrams, with one-click "Fix in" buttons for Claude Code, Codex, Cursor, and Devin (Greptile agent page).

Personalization is a first-class part of the product: custom rules written in plain English, directory-scoped config through .greptile/ and greptile.json, auto-indexing of existing rule files, and learning from the team's PR comments and reactions (Greptile homepage, key features, enterprise page). Greptile puts its scale claim at more than 22,000 teams, a vendor figure (Greptile homepage).

TREX, Greptile's runtime validation product, writes tests for a PR and runs the branch in a sandbox, attaching logs, screenshots, traces, or videos to failed comments; Greptile claims TREX catches about 20 percent more bugs than review alone, a vendor number rather than an independent result (TREX page). TREX is labeled beta in the documentation, and the homepage still routes it through early access, while the pricing page already prices a TREX review at 3 credits (key features, Greptile homepage, Greptile pricing).

Greptile describes itself as the central validation layer, the independent code validator for every coding agent (Greptile homepage, independence page). That is vendor framing, but it describes the shape accurately: it validates work an agent or a human already produced.

Review-time validation and edit-time context

The role difference is the whole comparison, and it is sharper once you know both products use a graph. Greptile's graph exists to give its own reviewers callers, dependencies, and ripple-effect context, and it stays inside the review pipeline (graph docs). Symvanta exposes its graph as MCP tools the agent calls mid-task. Before an agent edits a shared function, it can ask Symvanta for the blast radius and get back every caller and dependent across files and linked repositories, so it knows what breaks before it touches anything (Symvanta MCP tools). Greptile catches what slipped through before the change merges; Symvanta reduces what slips through by handing the author the map first. The two can run side by side, and the who-should-pick sections below say when each one earns its place.

That distinction is the subject of why AI coding agents fail on large codebases: the agent finds a plausible match and guesses what it is connected to. A reviewer catches some of those guesses once they are on the page; a graph keeps the agent from guessing to begin with. The tradeoff between search and graph is code embeddings vs. code graph: search tells you what looks related, a graph tells you what is actually connected.

What each exposes over MCP

Both ship an MCP server, and this is where the difference gets concrete.

Greptile's MCP exposes its review product. The current tools reference documents twenty tools across account discovery, pull requests, code reviews, comment search, custom context, a repository knowledge base, and analytics: fetching unaddressed comments, triggering a review, reading or creating coding patterns, searching the knowledge base, and reading review analytics, among others (Greptile MCP tools reference). The point is to bring review feedback and repo knowledge into the editor: fetch comments, apply suggested fixes, check review status, and resolve threads without leaving the IDE (Greptile MCP overview). The server accepts OAuth sign-in or an organization-scoped API key, and the documented clients include Claude, Cursor, VS Code, and Codex CLI (tools reference, MCP overview). What the tools reference does not document is a graph traversal tool: callers, dependencies, and blast radius are computed inside Greptile's review pipeline rather than exposed for your agent to query (tools reference, checked 2026-09-21).

Symvanta's MCP exposes the graph itself. relate answers callers, dependencies, blast_radius, implementers, heritage, and chain; find_node resolves a symbol to its definition and signature; find_http_route maps a method and path to its handler; diff_impact reports what a change set reaches. Semantic and text search sit beside the graph for discovery. The agent is not reading someone's review of the code, it is querying the structure of the code directly (Symvanta MCP tools).

Pricing, as of September 2026

Greptile is self-serve with a free tier (Greptile pricing):

• Starter is free for one active developer with unlimited repositories and 50 credits a month. One credit is one standard review and three credits are one TREX review.
• Pro is $30 per seat per month with 50 credits included per seat and $1 per additional credit, plus unlimited users, custom rules, and unlimited connected apps. Admins can set a dollar cap for extra review spend, and reviews pause when projected spend reaches it (billing docs).
• Enterprise is custom, with a self-hosting option, SSO/SAML, GitHub Enterprise support, a dedicated Slack channel, and custom DPA, invoicing, and payment terms.
• A 14-day free trial with no credit card applies to the paid paths (Greptile pricing, agent page).
• Qualified open source projects with MIT or Apache licenses get Greptile free, and pre-Series A startups under $2M in revenue get 50 percent off (Greptile pricing).

The fine print on billing is worth reading before comparing per-seat numbers: an active developer is anyone with at least one completed review charged to them in the billing period, PR reviews are charged to the PR author, and overage credits are counted per author rather than pooled across the team (billing docs).

Symvanta is self-serve and per seat: Starter is $19 a month for one seat with up to 5 repositories and 2 projects, Pro is $29 per seat a month with unlimited repositories, SSO/SAML, and customer-managed encryption keys, and Enterprise is $99 per seat a month with a 15-seat minimum, on-prem and self-hosting, SCIM, audit logs, and bring-your-own-LLM (Symvanta pricing). Every plan includes a 7-day trial with no credit card (Symvanta pricing, MCP endpoint).

The billing shape differs, not just the numbers: Greptile charges per seat plus review credits, so the bill tracks how many reviews you run as well as headcount; Symvanta charges per seat, so the bill tracks how many developers point an agent at the graph, independent of how many changes they ship.

Cross-repo and deployment

Greptile's review context reaches beyond a single repository. Repo Clusters group related repositories so that a review in one reads the others read-only, up to 20 GB per cluster, with suggested clusters based on shared contributors; context.repos in greptile.json does the same for a single repository (cross-repo context docs). Review integrations cover GitHub and GitLab, including GitHub Enterprise and self-hosted instances, and the self-hosted deployment docs add Perforce; the MCP tools reference also lists azure and bitbucket as repository remotes (enterprise page, deployment options, tools reference).

Deployment is cloud or self-hosted: Docker Compose on a single Linux VM for teams up to about 100 developers, Kubernetes for 100 or more, and air-gapped installs, with OpenAI, Anthropic, AWS Bedrock, Azure OpenAI, or GCP Vertex AI as model providers (deployment options). Greptile documents SOC 2 Type II on cloud along with SSO/SAML, audit logging, and role-based access, and states SOC 2 Type II, HIPAA, and GDPR compliance on its enterprise page (key features, enterprise page). Self-hosting requires a license and a sales conversation (deployment options).

Symvanta links repositories into one project and matches the couplings a per-repository read leaves out: HTTP call sites to the routes they hit across services, SQL table access to the ORM model that owns the table, and queue producers to consumers on the same channel (Symvanta MCP tools). Indexing is branch-aware, so an agent can pin a session to a tracked feature branch or overlay uncommitted working-tree edits (Symvanta MCP tools). It runs as a hosted MCP endpoint by default, with an on-prem bundle on Enterprise, and it works with Claude Code, Cursor, Codex CLI, Windsurf, VS Code, and any MCP client.

Side by side

Who should pick Greptile

Pick Greptile if the gap is what happens once the code is written: a consistent reviewer on every PR, findings grounded in the full codebase and your team's rules, a learning layer that adapts over time, and runtime validation from TREX when review alone is not enough. It is a mature, focused product for review-time validation, it covers code hosts beyond GitHub, and the editor loop (Fix in X, MCP, the Claude Code plugin) is wired in. If your reviewers are the bottleneck and your agents already produce acceptable diffs, this is the layer that catches what they miss.

Who should pick Symvanta

Pick Symvanta if you want the agent itself to know the code before it edits: exact callers, dependencies, and blast radius over MCP, across linked repositories and pinned to a branch, with a working-tree overlay for code you have not committed yet. It is the map the agent reads while writing the diff, so fewer bad diffs reach a reviewer at all. The endpoint is included on every plan, the trial runs 7 days, and pricing lists the seat math.

The two are not mutually exclusive. A team can give its agents the graph through Symvanta and still run Greptile on the resulting PRs, which is the strongest combination: the map during the edit, the review before the merge. The question this page answers is which of the two closes your current gap.
